Ingenic Jz4740/Jz4732 players

I'm so happy that my onda vx747 clone mp4 player which I have had for almost a year has got rockbox port. Though it's not completed n fully supported yet, but it really rocks. Thank to Rockbox n the developers especially to mcuelenaere.

BTW, I can't help with the programming, but I can inform that my Mp4 Player is "Simbadda Deo Vision 3.0" which is an onda vx747 clone. It works perfectly with custom VX747 BBE Audio firmware from mp4nation. This player is available in Indonesia. I don't know in the other countries. So I guess later when the port is fully supported, Simbadda's owner can try it as well.
The current firmware shipped with my simbadda player sucks. So I hope this rockbox port will be supported soon.

I also haven't tried to compile the SVN code since I don't know how. Any chance giving me the compiled version

See this link.
Extract it to the root of a SD card and copy .rockbox/rockbox.bin as onda.bin (for usbtool, see OndaVX747 wiki for more info).

All Onda VX747-related devices/clones (and VX747+, VX777, VX757(?), perhaps more) should be supported with this build.

Other ChinaChip devices (like VX767, Ainol V2000SE, ...) shouldn't require much porting as the basis has already been done.

Is this port suspended coz I don't see any further post in this forum?

No, the forum thread just doesn't really reflect the port status of the Onda VX747.

Any chance this port would be fully supported in the next Rockbox 3.2 ? Correct me if I'm wrong.

Probably not.

I downloaded the link for the sd files. See this link.  I extracted them to a fat16 sd card.
I found no onda.bin in the download. So I renamed bootloader2.bin to onda.bin
I complied usbtool now when I type sudo ./usbtool 10 the computer screen says success but the 747 does not load rockbox. What am I missing?

Also sorry to ask in this thread.I did not know where else to ask.
 Any way thanks for any advice in advance

Rockbox isn't compiled with FAT16 support by default, so you'll need to either compile it yourself or reformat it to FAT32.

I complied usbtool now when I type sudo ./usbtool 10 the computer screen says success but the 747 does not load rockbox. What am I missing?

I'm not sure where you got bootloader2.bin from, but if it's the Rockbox bootloader you'll need to hold down a button (not the volume up) to display debug information.

But I would rather advice you to rename rockbox.bin as onda.bin - as this will also work - and you don't need to have a bootloader if you use usbtool.

edit: oh and Onda VX747 is now in the build table, so you can get the most recent version here

wow that was fast. I was going to edit my post to say I used second_bootloader.bin as onda.bin
Ok I'll reformat card to fat32. Where do I find onda.bin Rockbox.bin is not in the download link you provided. And you mean hold down the m button while I do ./usbtool 10 ?
Thanks in advance again

[mcuelenaere]

Can't recall any file named second_bootloader.bin

Where do I find onda.bin? Rockbox.bin is not in the download link you provided.

It's in the zip: /.rockbox/rockbox.bin

And you mean hold down the m button while I do ./usbtool 10 ?

Yes, you'll need to hold down the the M button (or the - ) if you're trying to load the bootloader and would like to see the debug information (which is likely just going to say it can't find .rockbox/rockbox.bin on the microSD).

If you're going to upload 'normal' Rockbox this won't do anything, and Rockbox will power on the LCD anyway.

All right sorry to have bothered you. I downloaded that zip file 3 times there is no rockbock.bin I saw a rockbox747 file.
I was able to load the qutopia linux thing. I thought this would be easy.
The instructions are a little to vague. Not everyone has compiling experience In your instructions you say Download usbtool from SVN and read the README. Well you also have to download some other files from there and you do not mention that. Can you check your zip file and make sure you did not leave out the rockbox.bin see attached picture. Screen shot of the zip file opened. Please have a look!

Oh, sorry; I meant rockbox.vx747 instead of rockbox.bin 
You'll need the bootloader, as rockbox.bin doesn't come with rockbox.zip

I know the instructions aren't that good, I'll need to rewrite it a bit but the whole 'upload firmware to the device' process isn't finished actually (just as this port).

I'm currently more focused on getting Rockbox to work on the device than getting other users be able to replicate my case..

I had some success on my Onda 777.
I returned the retval in the "mmc_select_card()" function earlier to see where the error (ATA Error: 11) occurred and then suddenly Rockbox boots up fine.

if (sd2_0)
    {
        retval = mmc_read_switch(&request);
        if (!retval)
        {
            mmc_switch_hs(&request);
            jz_mmc_set_clock(1, SD_CLOCK_HIGH);
        }
        return retval;    //  <--
    }

It's in the "ata-sd-jz4740.c" file.
After booting Rockbox the touchscreen doesn't work. With an older revision it worked but only 1 out of 10 times.
Do I have to press a button to activate it?

Are you sure you aren't just in the 3x3 grid mode? (vs absolute point mode?)

And no, there's no need to press a button to activate it.. Perhaps this is a calibration problem?

I'll look into it (and ata-sd-jz4740.c) later.

[slowmoe]

How can I find out if I'am in absolute point mode?
The times it works its in 3x3 grid mode.

Some people seem to have gotten Linux booting on these players: http://code.google.com/p/jz-hacking/wiki/Index?tm=6

Look at Setting->General Settings->System->Touchscreen Mode

I know of it, this is Yajin's blog (containing how-to's).

(btw plugins are working now)

[mcuelenaere]

Regarding the touchscreen issue: this should be fixed in current SVN now (USB fix isn't still in yet).

Audio also remains a problem..

I've read your post in mp4 nation forum about installing rockbox to onda vx747. My player is SImbadda which is Onda vx747 clone. I use linux Slackware to upload it to my player, but I got error code on the player's screen :

ATA error = -1

What was wrong?

I've tried it using Windows XP Service Pack 2, and the player's screen was just blank without any output. The usbtool produced error too.

What was wrong?

Thanks in advance.

What SD card do you have? (an SDHC one?)

[cluex]

It's 8 gb, and that's right SDHC

So it has something to do with the SDHC card?

Thanks
