[flashrom] flash erase failure

[Thao Hoang]

Hi there.
 
I'm trying to use flashrom and although the program can detect both my chipset and my flash part (which are both tested & supported), the erase routine fails.  (Although I don't think it even erase since the content read after this failure was the same and the board does boot up properly.)  What do you think is going on?  Do you think it's something with my mainboard (per some of the discussion I have seen?)
 
Here is what I get when I do a write.... Thanks also for all the good work!
 
root at slax:/home/user/flashrom_folder/flashrom_unrelease# ./flashrom -f -w backup.rom
flashrom v0.9.1-runknown
No coreboot table found.
Found chipset "Intel ICH7M", enabling flash write... OK.
This chipset supports the following protocols: LPC,FWH.
Calibrating delay loop... OK.
Found chip "SST SST49LF004A/B" (512 KB, FWH) at physical address 0xfff80000.
Flash image seems to be a legacy BIOS. Disabling checks.
Writing flash chip... ERASE FAILED at 0x00000000! Expected=0xff, Read=0x49, failed byte count from 0x00000000- 0x0000ffff: 0x13de

Your flash chip is in an unknown state.
