I'd say that this CPU/microcontroller is the most limiting factor to get
Rockbox on these players: Rockbox is only built for and running on
32 bit cpu
cores, so this Z80 8/16? bit will require some work to get Rockbox
for. We
once had it buildable for a 16bit CPU (calmrisc for one of the older
Archos
gmini models), but that particular port was abandoned and most of
the long/int
cleanups of those days are likely gone by now.
The data sheet says 8bit! There is a DSP that does the MP3 decoding and a DMA
controller, so most likely the z80 does little besides reading the FAT
filesystem and setting up the DMA to pipe data from Flash to the DSP.
