I have a problem when i try to write my bios code into the PMC PM49FL004T chip. the foollowing error appears:
"Write failed Address=0x000000, Buffer=0x49 Device =0x40"

When i try to read, i have no problem.

Does anyone know if there is a software problem or a hardware problem?

I wish anyone could help me.

Thanks for all!!

1. Can you get correct ID of the chip?
2. Did you erase the chip before write?
Do a blank check before write.
