  I have a ATMEL AT91RM9200 board with u-boot 1.1.2
and Intel TE28F640J3C flash.

  I can burn u-boot image to flash when the board is
booted from internal ROM. But I can't erase sector 1
of the flash when it is booted from external flash.
Strangely, other sectors can be erased sucessfully
expect the sector 1 which u-boot image will be

I am sure that I unportect the sector 1 and I still
get an erase timeout.

BTW, I use CFI driver for Intel flash.

Someone, can give me some light ??
