Pampersrocker:
with usernames discoverings I've found out that my e260v2 also have radio: I've just installed the e200pF firmware on my player and could listen to radio, so there'll may not be some differences between the v2 models...
sry for my English :)
username:
i guess every e2x0v2 model has radio functionality. the reason why there are A and F versions is that in the A version you can select radio settings->fm region world, u.s. and japan, whereas the F version only has world but not japan. this is probably due to the fact that german (and maybe other european) authorities use some frequencies in the "japan fm region" for their communications.
nevertheless, i wonder why sansa sells devices in germany with have radio chips built-in but are disabled via firmware, although there is a firmware which excludes the frequency range which normal people are not supposed to listen.
hope not too off-topic.

Due to licensing costs in Europe - it costs more to sell a device with a radio as you have to pay for the licence for it.

atomikpunk: when I tried to patch the firmware with the led blink code (just to see if it's there) I got a linker error:
--- Code: ---arm-elf-ld -e 0 -o test.elf test.o
test.o: In function `loop2':
: undefined reference to `loop1'
make: *** [test.elf] Error 1
--- End code ---
I'm thinking it has something to do with the fact that we have one loop inside another. I've got arm-elf-ld version 2.16.1.
As a side-note, I won't be able to test stuff until Wednesday, I've got some restant exams.

I scratched my head this morning and linuxstb found the problem: comment line 33 is not terminated
EDIT:
fragilematter, you shouldn't try this code on the e200 because the GPIO mapping is different.
Instead you should reverse engineer the firmware to find the corresponding registers for your device.
/EDIT
by the way thanks you so much atomicpunk for this finding, this is much better to look for light rather than count the seconds ...
I have written a pattern search test, and tested 2 library blocks: usb_functio and otg_functio, and they are not loaded at their base address, neither when I boot the Clip by usb.
After work I will look for patterns in the FAT32 partition, maybe the NAND is enabled and mapped at boot ? Somehow I doubt it but it's worth a try
