c240: OF boot / microSD issues

[alexs]

Finally got rockbox running on my c240. Cool :-) Thanks rockbox team!
But there are some issues still left.

1. OF booting. I only can boot /System/OF.mi4, but not the hidden partition. Should it be so, or there's something wrong? Here's what it says when hold |<< key during boot:

Rockbox boot loader
Version: r14749-070919
Sandisk Sansa c200
Partition 0: 0x06 959
Partition 1: 0x84 20 M
Loading original firmw
Trying firmware partit
BL mi4 size: E000
Can't load from partit
Invalid file format

Trying /System/OF.mi4
mi4 size: 2E0C00
CRC32: 26E215C4
Model id:
Binary type:
Calculated CRC32: 26E2
Searching for key:
c200...found
c200 key used

If there's no OF.mi4 in /System, bootloader complains about OF.mi4/OF.bin and then just turns the device off. No white screens, nothing. If there is OF.mi4, it boots and works well.


2. microSD. Rockbox can't see it. Not a trace in file browser, database update finds only song from built-in flash, System/Debug/View disk info shows "[microSD 1] Not found!".
(microSD 0 is built-in flash, isn't it?)

OF has no problems accessing external microSD card.


Rockbox was built from sources, svn revision 14749 (checked out yesterday), binutils-2.17, gcc-4.0.3, host system is linux.

Did you install with sansapatcher?  That's the only way to keep a copy of the OF in the firmware partition.

I believe the microSD doesn't work yet on the c200, but I'll let someone who knows more than me answer.

The microsd detection is currently disabled until I can get a card to test. If you are compiling your own builds, I can make a patch for you to test.

For the record, also not working properly: FM (same chip as e200, but different hardware init), recording (someone needs to enable and test to see if it works & what needs fixing), and battery (needs the proper limits).

Did you install with sansapatcher?

No, binary one refused to work (that was e200 only version I guess), and it wasn't clear which P5022.mi4 should I use to build it from sources.

That's the only way to keep a copy of the OF in the firmware partition.

Oh, I see. Just reinstalled the bootloader using sansapatcher, and it succeeded booting from hidden partition. Thanks!

If you are compiling your own builds, I can make a patch for you to test.

That would be nice. I'm new to rockbox development but if there's some way I could help I'd like to.

hello,
could you please send me the patch for microsd ?
thank you very much for your work anyway.

I'm also interested in the SD patch, would make it much handier loading it up with music. Been too distracted with personalizing the UI to start using the thing yet, but realized this was a sticking point.

[lowlight]

There is no patch. I have a microsd card of my own now to do testing. When I (or someone else) gets it working it will be commited.

thanks for the answer
