I am looking at porting rockbox to the M-Audio microtrack. My
application is a little different, I want to make it a more versatile
recorder and am looking at using the rockbox firmware as a base for my
application. Its based on the PP5020, has a AK5365 codec, 16MB RAM, 4MB
Flash. It takes a compact flash card for recording to. It doesn't load
the firmware of the CF. To update the firmware you have to copy it to
the card and then use its own internal software. It has one unmarked
header, could be JTAG, although out of the 8 pins, one is ground, one is
3.3V and the rest look to have pull ups on them.

My main stumbling block is how to get the new firmware on it without
turning it into a brick. Does anyone have a datasheet for the PP5020?
It would be nice if it could load firmware off the CF card, but I
imagine this is going to require a hacked bootloader. Has anyone got
any suggestions on how to attack this one?
