Rockbox and Compact Flash

[viperX]

For jeremania ; I've sent you the file by email.

For Llorean/Petur; please comment what to do next. It is my first "bug" with Rockbox. Should I log the bug in Flyspray?

Regards

[petur]

yes, put all you found out in a flyspray bugreport

Just wanted to say thanks Petur for the build! My H332 is now complete!

So guys is this being worked on, i have no idea how to go about fixing this kind of thing but I'd be happy to test builds and if anyone has the last working build for a 5g ipod that they coulkd email to me that would be phenominal.  Thanks.

Hi,

We have tracked down the call which is causing this issue with the 5g/5.5g iPods and certain CF cards.

It is not a permanent fix but it seems to work. I have posted the build on the following page :-

http://www.tarkan.info/20080702/tutorials/iflash-and-rockbox

Try it out and let me know how you find it.

regards, Tarkan

Could you link to the patch for convenience?

Thanks so much tarkan!

Can you please offer more details and a patch? Also note that we are strongly against the distribution of binary-only builds, you should always provide the source code when offering a custom build (as per GPL)

[AlexP]

Not only are we strongly against it, but you cannot do it.  You would be violating the GPL (and therefore Rockbox's licence).  I don't mean this to sound aggressive, but I just wanted to point out providing the source is a requirement not a preference

Petur,

I will post up a diff later on.

Details are as follows :-

iPod 5g or 5.5g with certain cards throws up a PANIC ATA -1 error, the current build works ok on CF cards like the Sandisk Extreme III 16Gb but gives the error when used on the A-Data Speedy 32Gb.

Other symptoms of the error are, at boot up it hangs for about 10seconds at the boot up/splash screen and the backlight at 50% brightness.

Removing the following line from the ipod_video confirguration and reset section, cures it but this just a clunky fix. The root cause needs to be determined.

firmware/target/arm/system-pp502x.c         
remove LINE 311               DEV_RS         = 0x3ffffef8;

Hi Tarkan;

Is it expected that this will fix the problem on 4G grayscale too?
I'm afraid the instructions need to be slightly different then, I'd be happy to test in 4G GS if you instruct me to do the right changes at the source.

Thx

[tarkan]

Here is patch file for the changes I made http://www.tarkan.info/wp-content/uploads/2008/07/patch.txt

ViperX, sorry I don't know much about the 4g or the problems you are having. If you did not have the problems on builds before r16258 then it is possible the same lines of code causing the problems in the 5g could be causing them in the 4g.

Sorry ViperX, just realised you have the means to do your own build - It is worth trying it out, remove line 353 in the file /firmware/target/arm/system-pp502x.c

If that does not work try removing the whole block lines 344 - 356 inclusive.

regards, Tarkan

I have the same problem with the 4G.  I've spent the day trying to install Cygwin (can't find the setup.ini file at download.rockbox.org, probably because it is in the cygwin directory).  Then I installed VMWare and compiled the bootloader, but it still doesn't work.

How exactly can I patch that system file?  Can you please create a diff file for the 4G, or instruct me in the exact commands to edit the file directly?

I googled vi and learned how to edit system-pp502x.c to comment out the offending lines and created my first patch.  Thanks Tarkan for all your help in finding the problem and setting me on the right path with the file supplied.

[viperX]

Bingo!

It works too for 4G in the latest build deleting just the line:

DEV_RS         = 0x3ffffef8;

I'm sorry I did not write the line number  but it is slightly below line 353 (that was true for 16259).

I guess you can produce an offical patch now...

Many thanks for fixing this

[1ny0urfac3]

so has this been fixed in the daily builds now?  I'm still using tarkans build
