Now i am working on SST49LF004B 33-4C-NHE 0710022-CA with the motherboard K8Upgrade-VM800
The flashrom detect flash device on this board, But the erasing and writting operation is not happening properly hier flashrom output :

Now we are analysing the code but we are not getting idea...
please guide us how to change the code ..we are ready to fix the things.
Thanks in advance........
