Title: Meizu M6 "miniplayer"
Post by: nexxyz on April 23, 2007, 08:26:58 AM
Hi!

I've used Rockbox on my iRiver H340 for a while now and love it!

I recently ordered a Meizu M6 "miniplayer".
http://en.meizu.com/product_m6.asp
Of course "What about Rockbox? I would love to stick with it!" came to mind.

Searching for the player I found the following thread (has been locked):
http://forums.rockbox.org/index.php?topic=7430.0

It apparently contains a link to a pic of the innards of the M6:
http://my.opera.com/inokia/albums/showpic.dml?album=83493&picture=1088876

It also contains an outdated link to a page that supposedly states that the CPU is the same as in the iRiver E10, which is also mentioned in this thread:
http://forums.rockbox.org/index.php?topic=4291.0

I'd really like to see a port to the Meizu M6 happen, and would be more than willing to actively work on it and do some heavy time investment, as well as limited money investment (for development players etc.) as soon as I am convinced we have a team that can indeed tackle the problem at hand, and have enough info about the hardware, or at least rather reliable methods of obtaining this info.

I would consider myself an average programmer, and have never participated in anything like this before, so more experienced members would most definitely be needed to see this port through. I have coded a bit for the Nintendo DS, but nothing big (yet). I would see such a project as a possibility to enhance Rockbox compatibility, and of course, to have fun and learn a lot at the same time.

If you are interested in working on such a port project, I would be quite happy to hear from you!

As usual, start with reading the NewPort wiki page as it gives a good overview of what you need to go through to make a new port a reality.
Title: Re: Meizu M6 "miniplayer"
Post by: markun on April 23, 2007, 10:32:36 AM
a better place to ask for help would be a Meizu forum I think

Here's a little bit of information on the CPU in the M6:

Thanks for the tips!

I read the New Ports FAQ/wiki page, of course, and am going to look around the Meizu forums, but first I wanted to check if there are any Rockbox enthusiasts around that would be interested in such a project, since I guess if there aren't any, I might as well drop the issue altogether...
Title: Re: Meizu M6 "miniplayer"
Post by: Llorean on April 23, 2007, 11:08:09 AM
The key is finding anyone to work on it, they don't have to be Rockbox programmers beforehand. And the most likely people are owners of the player. It really doesn't matter if "Rockbox enthusiasts" are interested in it or not, in the end.
Title: Re: Meizu M6 "miniplayer"
Post by: Bagder on April 23, 2007, 12:37:55 PM
I can assure you that there will be a team of Rockbox hackers ready to welcome your port and to help and guide you through it. For the actual hands-on hacking you of course need to own the device the port is made for.
Title: Re: Meizu M6 "miniplayer"
Post by: nexxyz on April 24, 2007, 07:32:56 AM
Thanks a lot for the info, I also posted in the Meizu M6 Rockbox thread at meizume.com:
http://www.meizume.com/showthread.php?t=1371&page=2

As for Rockbox hackers helping but needing the hardware: I imagine the player will become more widely available in the near future, as it seems to get pretty popular...and as I said, I am willing to invest time and a bit of money, so once the basics are cleared, and we've got the people together and know it is possible to do the port with acceptable quality we will see where necessary players for development might come from for the interested skilled people who cannot afford them.

EDIT:
Found a nice photo series including disassembly:

What adout port to M6?

PS: Sorry for my bad english ::)
Title: Re: Meizu M6 "miniplayer"
Post by: nexxyz on May 23, 2007, 12:43:50 AM
It seems so...

Afer asking around the Meizu community, I got the impression that there is not really much demand aside from myself for such a port.

The original firmware is not great (heck, it doesn't even play back some mp3s correctly!), but I have decided I can live with it for now.

However, my statements above still hold true should someone start a port or convince me otherwise on the point of demand.

so here is this binary http://stream.ifolder.ru/5471399 it is SDRAM_image.bin 1.23 mb .bin file.what shall we do next?


I didn't post that file anywhere because I wasn't sure if it was a copyright violation (maybe not since it's part of the firmware update which is downloadable for free)

I've disassembled the file to try and find out more about the hardware. It can be quite a lot of work, especially if you are new to (ARM) assembly language.

Also, is there some kind of rescue mode? If this file gets written to flash memory it would be quite easy to accidentally destroy your player...
Title: Re: Meizu M6 "miniplayer"
Post by: vcf on February 24, 2008, 06:36:59 AM
markun, yes there is a way to rescue the player.if when it is connected to the computer and  computer dont identify it than you should youse dfu tools http://www.meizume.com/miniplayer-m6-sl/18-dfu-tools.html yes the file is getting written in the flash memory as i understand.I have absoulutly no idea hoe to use (ARM) assembly language.i am an absolout beginner in it.so what should we do now?so have you knowen anything new about the hardware after dissemblying the file?what should be the result of it?

FraL and dimap, start by reading this:

http://www.rockbox.org/twiki/bin/view/Main/NewPort

One way you can also help is by testing the build as it progresses; i.e. compile and run it on your Meizus and report back with results.

That's not going to be for a while though - since there's currently nothing to run at all.

we are working and trying to find out more about (ARM) assembly language.bot noone understands it.so we need just to wait when markun will find out something new from that code ::)
Title: Re: Meizu M6 "miniplayer"

There are more than a few of the devs who have a very good working knowledge of ARM assembly code, they're just not working on this port :)

Post by: markun on February 26, 2008, 04:26:18 AM
I don't have a Meizu M6 and no plans to buy one, so it would be better to ask for help from existing meizu owners. Here for example:

markun, you said that you disassembled the file to try and find out more about the hardware.as i understand there is no use to have player to read asm language. do you understand this language? if yes could you just tell us something about players hardware e.g?

EDIT:

here is some information about the CPU http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=212&partnum=SA58700

Post by: markun on February 29, 2008, 02:36:15 AM
Yes, we've found that webpage before (but Samsung keeps changing the URL's). Unfortunately I also didn't find any datasheet. Maybe the various components (USB, RTC etc) work the same as in some other samsung chips for which we do have datasheets.

EDIT:

I think I've found a nice deal for a Meizu M6 (82 euro for the 8GB version) and will probably buy one next week :)

EDIT:

I just ordered it!

Well, the code doesn't seem to be protected. Now you should try to compile the rockbox source to ARMB. I'm not sure exactly how it works, but you'll need to identify the RAM address, Flash address, MP3 chip address, screen address and so on. Basically, probe around.

markun, our player has SA58700 that meens our player has audio codec. propably the sdram controller was pictured like it.
p.s the samsung support answered me thatthey ont have the data sheet. but they sais were can we reach it. so i will try.
here are some more parts of players hardware with specs

Post by: markun on March 04, 2008, 02:14:37 AM

There is many interesting code in SST39VF800.dfu, eq. interrupts code.


Indeed. I disassembled it yesterday. Because of the "Thumb only" error message in there I thought there would have been some Thumb code, but it's all normal ARM so far. I guess the SST39VF800 is the 1MB NOR flash included in the SA58700 (http://www.rockbox.org/twiki/bin/view/Main/SamsungSA58#SA58700), what do you think?

Right now I don't really have a lot of time to analyze the disassembled files. Are you trying to figure out some register addresses etc?

btw, With DFU-Util (http://wiki.openmoko.org/wiki/Dfu-util) from OpenMoko it could be possible to run code from SDRAM without flashing it, that would be really useful for development. Hopefully it works.

EDIT: just looked at the code in Blues_MSC.bin file from the dfu tools and it's very similar to the firmware updates.

As I know, SA58700 of M6 does not include  the Audio codec WM8731L, because this is a special chip for M6. The ceo of Meizu said he demanded Samsung to remove Audio codec.

M6 SL changed the FM Chip from Sanyo LV24000  to Philips TEA5760.

FM chip and power management chip (LTC3455) for M6 SL
Title: Re: Meizu M6 "miniplayer"
Post by: sotux on March 08, 2008, 10:40:19 AM
sdram and sensor for M6 SL.

There are 4 versions for M6. They are T1, TP, SP, SL(Ordered by production time).
I bought a T1 (first version) at the end of 2006.
This version has some problems of hardware design such as bad FM effect and sensor out of control. So Meizu changed sensor chip and circuit design since TP version.(From QT411 to QT1106)

There are also differents from their TFT screen.
T1 and TP have a Toshiba TFT screen (I think this screen is better than SP's and SL's.)
SP and SL have a Samsung TFT screen, but the screen of SL is lighter than SP's.

Sanyo FM chip is not good so Meizu changed it since SL version and M3 (mini card)

Sorry. I made a mistake about the sensor chip. I've corrected it.
Only SL uses QT1106 and others use QT411.

Rockbox rules!!! I've installed it on a friend's H340 3 or 4 years ago... As soon as I bought the Meizu, I've hope rockbox will be ported on it... It's like a dream that's coming true!!! I'm can help you on ARM9 language, but maybe if you need some help coding c or whatever else you need, I might help you (not sure if I quite good to do this but I really would to help making this a reality).

Actually, I look for buying a 1GB meizu in order to help with test and beta version when first ports came...

If you rockbox guys see another way which I could you, let me know !!!

Great work, I was hoping to see a port on the m6. Is there a reason, why there is no info about the TP version on the reverse engineering page, or is it just, that the SP and the TP are so similar? I don't really have knowledge in ARM assembly, or embedded development, but If you need any testing to be done on a TP, I would be happy to help. Also, i have experience in C coding, if that can be of use... Keep up the good work!

Just build it as you build any bootloader.

how to run this code meizu_dfu m6sl  rockboot.ebn rockboot.ebn ?
meizu_dfu is in utils/. Compile it
Then run the command as I said.
(I'm not sure if it works in windows)
Title: Re: Meizu M6 "miniplayer"
Post by: wpyh on September 02, 2008, 11:08:09 AM
Thanks to gevaerts, I've also been able to run the test code on my M3.

1. Press and hold M.
2. Press and hold Play.
3. Plug it in.
4. Release Play.
5. Run "meizu_dfu m3 rockboot.ebn rockboot.ebn".
6. When it says "Clearing status...", release the M button.
7. Play around! Pressing the Play button will toggle the backlight.
8. When you're done (or bored), unplug the device. Nothing will be written on the device, so no data will be lost (legally, I don't guarantee this though).

The above procedure should be the same for M6 TP and M6 SP (just replace "m3" in the command with "m6").
Title: Re: Meizu M6 "miniplayer"
Post by: gevaerts on September 02, 2008, 03:22:21 PM
The new version doesn't turn off anymore on unplugging (at least on m6sl, most probably on m3, unsure about the others).

To make it easy to handle, it now turns off after pressing Play 20 times (it tells you this by toggling the backlight quickly a few times before turning off)
Title: More progress
Post by: gevaerts on September 11, 2008, 04:52:07 AM
The current svn version manages to read the touchpad.
The "keep powered on after unplugging" is disabled for now, so you have to keep the usb cable plugged in while testing.

It won't work as such on the SP. The GPIO pins for LCD communication are different. I don't know about M3.

I don't know about M3.

It won't work on the M3. The M3 has the LCD connected to the LCD interface in the SoC, and the picture is sent out with dma from memory to the LCD IF. Actually I was able to draw something on the M3's lcd with programmed io, but the code in question is not bulletproof yet.

Title: Re: Meizu M6 "miniplayer"
Post by: RichterSkala on October 26, 2008, 11:06:19 AM
So. Today instead of doing some work for university I decided to mess with my M6SP and you're progress so far (see if my little skills in coding could contribute a thing). But I wasn't able to get the DFU mode to work.
So first of all there seems to be two different methods: Press Power and M or press M and Play.

If I press Power and M, plug in the usb connection and run meizu_dfu M6 M6.ebn M6.ebn it stops at USB initialization, takes some time to state later, that it couldn't find a device. During that time lsusb will give no output either.
Same procedure with Play and M: meizu_dfu takes no time on USB initalization and skips immediately to "No device found".

What am I doing wrong? My host system is a plain Ubuntu 8.06 - any reasons there maybe?

i've a question regarding the spi connection to the driver ic of the m6sl lcd.
does anyone know how this is connected to the samsung arm chip?
is there another layout instead of this file M-P-V7.pdf (i guess this is not the m6 layout)? i was just wondering, because i had a look at the init_lcd_spi function and there are ports used (e.g. PCON4 bit2,3) which are not connected to anything.
where can i get this informations (nothing found on the wiki page of the meizu port)?

how do i get out data like that out of my m6sl anyway? i am clueless... ;(

i only worked with atmel chipsets untill now and those are documented, which isnt true for the meizu (for obvious reasons).. but i would really like to contribute.. maybe someone of you can give me some hints where to go for learning stuff like that ;)

Hey, guys. I own a M6SL. The official firmware from Meizu company sometimes is annoying. So I fully support porting rockbox onto Meizu players. Though I don't know much about arm, I have some C/C++ programming experience. If you need any help, please let me know.

EDIT: I can't get the through the dfu process. I am always got stuck at the get_cpu operation after "Wait a sec (literally)..." :(. Anybody can give me a hint?

saab_rider:

A bit of a cheeky request - any chance you/your friend could PM the original poster and explain that Rockbox is written by volunteers in their spare time, and it would need a chinese speaking volunteer to invest a very large amount of time to keep a translation up to date.

Just wanted to let other Meizu M6 users know...  I as BigBambi suggested a while back and contacted the Chinese guy who posted in this thread in Chinese (http://forums.rockbox.org/index.php?topic=10078.msg124881#msg124881) (my translation is right below it).

This is his response:

謝謝你!

Thank you!
I'm a student, and my English is weak.
I'm very familiar with China's MP3 market (I assume he means DAP market), and I have many MP3s (again I assume he means MP3 players).
Although I can't help RB due to the language barrier, however if anyone needs me to find a specific MP3 player or even a specific MP3 player's specs. I'll try my best to help!


So there you have it :) You can either contact the guy directly, or send me instead...

To those who can successfully run the DFU process on the M6SL:
          I have been stuck in the DFU process for a long time and have the same problem as yijie. Could any explain the DFU process on the M6SL more precisely? So we can find where the problem is. There are some people like me who are willing to help this project but can't run test code on M6SL because of the DFU problem. If we can run code on our player, I think more people can really help this project.

Post by: l4 on May 28, 2009, 05:56:26 AM
As there is few posts here about getting stuck at the GET CPU I have decided to dig into this.
During this process there is the part where you need to hold the buttons. To know you are holding them right (as wpyh suggests we are not :)), you can see in the lsusb --verbose (a linux command) the device is seen as 2 Blues USB DFU Device and also the DFU tool does not show the No device found.

If you look into the meizu_dfu source you'll notice there are duplicate lines of get_cpu(device) which was suspicious to me. Markun said he commented one of them out and the dfu tool works on his FreeBSD. I don't know if before modification it did not work for him but it did not solve my get_cpu() problem. I am not an experienced programmer but I will try to find out whats going wrong.

Guys who know their C and the sauce around, don't whine about not being to help cause of little difficulty and take a closer look at the get_cpu()  function of the dfu tool. I will try and will update this post in case I find some usefull hints or even solve the problem. (I own the M6SL version, please state your miniplayer version just in case ;))
Title: Re: Meizu M6 "miniplayer"
Post by: gevaerts on May 28, 2009, 06:24:40 AM
OK, there seems to be a lot of confusion about the meizu_dfu tool, so maybe I should mention some facts:

get_cpu() is executed twice to match the behaviour of the original windows dfu tool that's mentioned on the meizume forums.

meizu_dfu is designed to upload a firmware file, wait for it to start running and start its own dfu mode, and upload another file. This is because that's what you need to do to install the OF.
For running the rockbox test code, you only need one, and it doesn't speak dfu itself, so the second set of get_cpu() and upload fails.
Of course, some changes to the meizu_dfu code to have a mode where it only tries upload a single file (maybe by looking at how many files it's given on the command line) would be welcome

Title: Re: Meizu M6 "miniplayer"
Post by: l4 on May 29, 2009, 04:31:57 AM
I am glad gevaerts pointed out these facts. I have debugged and resolved my get_cpu issue which opposed to yijie's was in failing to get_cpu even before the first image was sent. Now what is happening is after sending the first image, the USB connection is reset to be reestablished with the upload code that has been sent in the first image. I got 'No Device Found' on the atempt to reestablish the connection. This is due to the player not being rediscovered during the 'Wait a sec (literally)..." message. This can be avoided by changing the waiting interval to 2 seconds.
If you encounter this issue just go to the rockbox/utils/meizu_df/meizu_dfu.c and change the sleep(1) to sleep(2) (in the code that is used for your version of player!). Now recompile the dfu tool and try again.
My status is now hanging on sending the second image. I assume the update code is not accepting it (most likely my fault) but I know its running as it is returning the CPU model S5L8700 Rev.2-BE  070831

Thanks everyone! Finally I get response. :)

To wpyh: I tried to hold two buttons down all the time, but failed again.  And if I press only M button, the command meizu_dfu updateNAND_BE_070831.dfu M6SL.ebn works.

Seems like after the first image updateNAND_BE_070831.dfu was uploaded, it begins to run. So, what is the address does it run from? Can we make rockboot.ebn run on this address and discard the second satge?

Hi all,
gevaerts lent me his Meizu M3 and I'm working on getting more stuff to work on it. So far we've been able to control the backlight brightness by doing interrupt-driven PWM, getting the i2c bus to work so we can talk to the codec and the real-time-clock chip. Hopefully we'll soon be able to communicate with the radio chip too.

The rockboot.ebn file is created when compiling the meizu bootloader. I can't really explain the entire building/compiling process here, but please have a look at the rockbox wiki pages on development, for example http://www.rockbox.org/twiki/bin/view/Main/DevelopmentGuide
Title: Re: Meizu M6 "miniplayer"
Post by: bertrik on July 07, 2009, 05:23:13 PM
Update on the Meizu M3:
We have audio out working with DMA-driven PCM. We can't access the NAND flash yet, so the first sound was done by compiling a 2-second audio clip directly into the bootloader. The uda1380 audio codec driver could be re-used from the iriver Hxxx port, but this driver will need some modification to properly work with the meizus (there are some differences in use of the MCLK clock signal for example).
FM radio can now also be controlled, again from the bootloader only for now.
The PCM can be easily enabled for the M6's too, the fm radio can be enabled for the M6SL only (the M6SP has a different FM chip).

The clean parts of this have been committed to SVN. To actually hear audio or control the fm radio on the M3, some hacks are needed that are not in a committable state yet. If people want to play with this, just let me know and I can make a patch that includes these hacks.

Hey, guys. It seems that this post haven't been updated for a long time. I hope people won't give hope for rockbox port on m6 series.
I request somebody who can run test code on m6sl to share your rockboot.ebn file with me. I really don't know why I can't run the test code on my m6sl, because I should be able to toggle the backlight if the code is run. I couldn't help to doubt that my cross-complier is not correctly built.

PS: I assume that the test code is run by replacing the firmware updating code. And the firmware update code is the first image file sent by the DFU tool during the normal DFU process. So our test code should be run just after the player accepting the first rockboot.ebn file. Do I need to reset the my player after that? Do I miss some thing?

Last weekend I was able to display a rockbox logo on my Meizu M6 SP. Unfortunately there is a spurious yellow line at the bottom of the screen (looks like part of the logo) and the player hangs after displaying the image. Probably the next thing will be enabling the SDRAM on the M6SP.

In principe it should be possible to run things directly from RAM in DFU mode, but I haven't been able to make that work on the SP yet (it did work on the Samsung YP-S3 which has the same SoC, using the M6SL DFU method). So I'm still running all test code from NOR flash now.

Small status update: I am now able to access the DRAM on the M6SP, I'll commit the change this weekend.
The hang after displaying the rockbox logo still puzzles me, the player seems to hang right after configuring the PCON_ASRAM register that controls the function of the pins used to interface with the LCD.

I think Meizu firmwares can still be found on the meizume forums.

SDRAM now seems to work on the Meizu M3 too (haven't tested it extensively though).

Also, I got some more insight on how the DFU mode works on the M3 and M6SP: the image that is sent in DFU mode is not a full RAM executable, but a kind of flash-loader plugin, with a couple of basic flash functions, like flash identification, device erase, block erase and flash write. There is a possibility that this mode can be exploited to write a kind of RAM-loader (as opposed to a flash loader), that can be used to bootload the main rockbox executable.

Hi guys. Finally I can toggle the back-light of m6sl using the bootloader generated by the rockbox project. This is achieved by modifying boot.lds and crt0.S in folder $ROCKBOX_HOME/firmware/target/arm/s5l8700. It seems that .text section and .rodata is mapped onto flash. During DFU process the flash is not accessible so we need to modify the boot.lds. I don't know modifying crt0.S is necessary or not, because I haven't test this new boot.lds with the current crt0.S file. I hope this will help guys want to get some reaction from the m6sl, though this task is so simple for these experienced developers.

PS: .txt is added to the two file name because this forum doesn't support uploading .S and .lds files.

Hello, guys. Now I am trying to understand the disassembled code. Because I am a newbie for embeded systems, I have diffcult to understand following code located in M6SL.ebn, offset 0x8578:
Code: [Select]
RAM:22008578                 LDR     R1, =0xFFF
RAM:2200857C                 AND     R1, PC, R1
RAM:22008580                 ADD     PC, R0, R1
It seems that the arm code should be aligned to 4 bytes. But after executing these code the arm processer PC will have an odd address of 0x**009583. So I am puzzled. Is this code meant to incur some sort of exception?
Title: Re: Meizu M6 "miniplayer"
Post by: saratoga on December 12, 2009, 12:32:07 AM
I'm not much good at arm, but it looks to me like that code just jumps ahead to the nearest 4KB boundary (address that ends in 1+0xFFF), so its probably just trying to align a code block with a page boundary.

Hi paul356, nice to hear you're having some success with the m6sl.
In theory you should be able to run code from RAM just by modifying boot.lds (making everything go into RAM). This works for me for the Samsung YP-S3 (which seems identical to the m6sl with respect to bootloading). For the YP-S3 I also modified meizu_dfu to upload only the first image. Running and testing from RAM is actually easier than running and testing from flash because it takes less time to do one test run.
A major next step for the m6sl would be to get the display working. There is already some code for that (written for a S6D0154 LCD controller), but I don't think it's working yet. You could also try the code from the m6sp, the firmware seems to use some kind of autodetection for the display. My m6sp uses the driver for the unknown LCD controller, but there is also a driver (in the same file) for a S6D0139 controller which could be in the m6sl.
