Hi,
I have updated the wiki page http://www.rockbox.org/wiki/XDuooX3 to add the PCB scans. Using this and some binary reverse engineering, I have concluded that similarly to the Fiio X1, it uses a SLC NAND + mobile DDR RAM MCP. The RAM size is 64MiB and the NAND size is 128MB.

Hi to all.
Hmm. It looks like a good platform for experiments on rockbox porting. But I do not see any uart pins on the board. Serial output is helpful for debugging.

MP3 players usually don't have any deug pins on retail versions.  The first part to a port is usually to make the screen work, to display some information. That's what I plan to do first anyway. I bought the player but I won't have it until another 10 to 15 days:

I'm very interested in this port. However, I have not much knowledge about embedded development.

Can I do anything to support this?
