Uh oh. Erase/write failed.Checking if anything has changed.

Good, writing to the flash chip apparently didn't do anything.
This means we have to add special support for your board, programmer or
chip. Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom at flashrom.org, thanks!
You may now reboot or simply leave the machine running.
