Our custom board is originally running VxWorks, and there is a full
solution on NAND
flash connected through GPCM. Because of this, our Linux can only try
to adapt to this.
I'm now writing GPCM NAND driver from the UPM NAND driver. Most function ca=
n be
copied from our U-Boot port. Now the NAND flash can be recognized, but ther=
e is
some bug in my driver, the kernel will oops for access 0x00000000, I
will continue
writing the driver next monday.
