[U-Boot-Users] U-boot for pxa255

[swamy]

Hi,
We have a custom built PXA255 board with 32 MB SDRAM, 32MB Flash( one
28F256L30b 16MX16 bit wide)
and FFUART for serial port. I am unable to boot U-boot after loading to
flash through JflashMM program. Flash loading is verified successfully.
1. How do I debug?
2. Does u-boot support the above flash configuration?
3. Are there any patches to u-boot to make it work for the above
configuration?
Appreciate your response
Regards,
swamy
