Sansa Fuze+

[danger355]

Hello,
the normal steps to build sbtoelf is to have an up to date svn checkout and to type make in utils/sbtools. You error definitely indicate something wrong; are you sure you have the sbtoelf.c ?
Then you should follow the steps in the wiki SansaFuzePlusPort page, everything is written. The directory in which is happen is not important, a fresh one will do.

Hi pamaury,

yes, i definitely have sbtoelf.c in the /sbtools folder. i followed the steps in the wiki, but it's still very possible i did something incorrect, so i'll try starting from scratch soon and see if that changes anything

@danger355
Starting from scratch can you give the exact sequence of command you type?

@Pamaury
ok I suppose I've build the stuff correctly and transfert it to the device:

Code: [Select]

root@debian:/home/jean-louis/Informatique/Rockboxfuse+/rockbox/build# ../utils/imx_hid_recovery/imx_hid_recovery 1024 bootloader.sb
Transfer size: 1024
ret 0
root@debian:/home/jean-louis/Informatique/Rockboxfuse+/rockbox/build#
But nothing hapen... Screen stay black nothing responding. Same after uplugging it. It stayed not responding for awhile and finally after several attempt repluging it bring the OF control back
for info here the dmesg sequence:

@metaphys
It used to work on your device, didn't it ? I haven't change much in the lcd code recently :-/
Did you account for the change in the bootloader.db file ? I'm now using the first 3 stages. Without the first one, usb is likely to not work properly. But that doesn't explain why the screen stays black.

[metaphys]

Yes it used to work 

I did this new build from scratch and followed the instruction on the port's page so I guess i did have the new db file... Confusing indeed. Let me know if I should test something else 

[pamaury]

If you are motivated, you could try to bisect to see which revision of the svn caused that. You can also try to change this in lcd-fuzeplus.c:
replace

Code: [Select]

default:
            lcd_kind = LCD_KIND_9325;by

Code: [Select]

default:
            lcd_kind = LCD_KIND_7783;

I just tried this, same problem (actually as it used to work it would have been surprising)

How can I bisect ? I'm not very familiar with svn, where can I read doc about it ? is it just

Code: [Select]

man svn ?

[pamaury]

There is the svn-bisect tool. If you are using git, there git-bisect.

[pamaury]

Any news about this screen problem ?

[metaphys]

Sorry but i'm again travelling around... I will tell you as soon as possible. But do you mean it works on your device? Isn't it strange? 

[pamaury]

I *think* I would have noticed if the screen didn't work on my device
the only thing I changed (except if I did a mistake) is that if the type of screen is not detected, it falls back the type 9xxx instead of 7xxx (don't remember the number). So it's a bit strange :-/

[pamaury]

Hum, my mistake, the wiki is not up to date. Thinking about it, I made two important changes:
- one about memory layout
- one about elftosb
Be sure to have the latest elftosb complied from the SVN.

I've updated the wiki. sorry for the mess

[pamaury]

Hi all,
As you may have seen for the SVN log, I've made some progress toward actually compiling the main firmware. I've also investigated dual-boot. The good point is that it is possible to build a firmware.sb file such that the OF will upgrade itself That means that installing the bootloader will be easy. However, I did it on mine and dual-boot doesn't work for some rason. I do not quite understand how the OF is booting, this is weird.
Anyway, I'm still working on that.

[pamaury]

Hi all,
I've been in holydays for the last 3 weeks and I probably won't be able to work on the Fuze+ next week but then I'll be back. Please don't send private messages to ask for some news.

[pamaury]

Hi,
again some news from the port ! I'm recently reworked mainy things about memory and the bootloader. I've implemented some ADC related stuff and I'm working on battery charging (not so easy with this chip). I've also fixed the USB tricky details so the bootloader now has USB support and works perfectly. I've tweaked it so one can access either only the main partition or the whole disk (to update the bootloader). Once charging is implemented, I'll move on to the audio drivers and to the touchpad one.
As a side note, for those who are interested, Freescale released the source code of eltosb2 as well as the documentation of the sb file format on their website (download section of the IMX233, perhaps need to register).
Please note that the wiki page is *not* up to date, and I still have some non-committed stuff.

[pamaury]

Hum,
I tried to flash the bootloader myself to what i thought was the bootloader partition and apparently it doesn't work. So I only have recovery mode working on my device now \o/ This is weird because either the ROM doesn't follow the documentation I have either I misunderstood it.

To recover from this situation, I would need a clean flash image. Could someone run recovery mode on some file I provide and do a partial dump of the disk ? This is completely safe and only requires linux + dd.
Thansk in advances.
