Dear Amit,

I'm sorry, but I never used  a  MBX  board  with  PPCBoot  or  U-Boot
myself, so my experience is limited.

There are two obvious errors here:

First, U-Boot must start at offset 0, not  0x100;  I  don't  know  if
FC000100  is  the correct address - if the "FC" prefix is correct (*)
then you must program the image to FC000000, not FC000100.

(*) The U-Boot configuration  for  the  MBX-Board  sets  TEXT_BASE  =
0xFE000000 so please double-check your address.

Second, the image size of >500  kB  is  wrong.  You  must  flash  the
"u-boot.bin" image, which should be in the 120..130 kB range.

Best regards,

Wolfgang Denk
