Cowon M2

<< < (3/3)

n158:
Found image of other side on 4pda.ru. It appears that M2 CPU is Telechips TCC7901. Another chip is 512Mb (4M×4Bank×32) Mobile Synchronous DRAM EOREX EM48AM3284LBB -6FE.


The CPU specification might be this: TCC79xx_DataSheet_V1.03-090123.pdf, but not sure.

Some info about Toshiba NAND chip:
Part Number: THGBR2G8D4JBA01
Capacity: 32 GByte
DQ Interface: Legacy(SDR)
Page Size (Byte): 16K
CE Signal & Ready/Busy Signal: 2 & 2
Power Supply:
VCC(V): 2.7 to 3.6
VCCQ(V): 2.7 to 3.6, 1.7 to 1.95

While dealing with NAND, document NandDesignGuide.pdf might be useful.

pamaury:
We usually don't support raw NAND because it requires FTL and no one wants to spend hundreds of hours doing so, but as long as there is a microsd slot it's okay (like the Cowon D2). However someone with the device needs to do the port and as far as I know, no developer of the project has the M2 or an interest in it.
