u-boot can not boot after change flashdisk from 8M to 16M
Hello,
Because need more flash disk space, I replace
ppc405ep board flashdisk 8M (intel 28F640j3 8MByte=64Mbite= 128k x 64) to 16M flashdisk (intel 28F128j3 16Mbyte=128Mbit=128k x 128).
I try to use the working u-boot.bin which is for 8M
flashdisk to boot the 16M flash disk, I use BDI/JTAG to write u-boot.bin in ppc405ep 16M flash memory, erase, write and read data workes and looks correct.
it failed boot. when power on, nothing happened.
where should I chnage in the u-boot source code from
8M flash memory to 16M flash memory?
before the 8M flashdisk memory is from ff800000-ffffffff, u-boot.bin image address is from fffe0000-ffffffff, then the new 16M flashdisk is from ff000000-ffffffff, I still put the u-boot.bin in fffe0000-ffffffff in 16M flash memory.
Thanks
Tyler

Have you ensured you programmed u-boot to 0xFFF80000. AFAIK, the ppc4xx series must have u-boot there.

There is no such restriction.
