Setting FORCE_WORD_WRITE to 1 in the cfi_cmdset_0001.c fixes the problem.

Thanks a lot. This works like charm :)

You should check the datasheet of m28w740hcb and at49bv642d.Maybe there's
something uncorrect when you write to your flash.Focus on the write option

the same. Hopes to help!

Hi list
I have replaced the at49bv642d nor flash memory on my Atmel ngw100 board
with the pin compatible m28w640hcb flash memory from Micron (formerly
Numonyx).
I can program the U-boot to the flash without problems using a JTAG. I can
also program the full buildroot Linux system using
6 matches
