Hi,
Thanks a lot for your info, but my board still can't work with binary file building with mainstone patch.
My board's info as following:
      1 CPU: PXA270
      2 SDRAM :0xA0000000 - 0xA4000000 64M
      3 BOOT: nCS<0> CODE: 0x00000000
      4 FFUART:
        GPIO34：FFRXD
        GPIO35：FFCTS
        GPIO36：FFDCD
        GPIO37：FFDSR
        GPIO38：FFRI
        GPIO39：FFTXD
        GPIO40：FFDTR
        GPIO41：FFRTS
      As I'm a newer to uboot and PXA270, so in my opine, after patched the uboot114 directory, I just need to modify the mainstone.h to fit my board.
      But I failed.
     Then after compared with start.S for other cpus such as ixp,
I found that the reset code are very similar to each other.
      At first I doubted about the reset code, so I modified start.S and lowlevel_Init.S with the start code of blob.
      But I failed yet.
     Could you possible give me some suggestion? Thank you very much.
Best regards
John
