Hi,

When I do execute the following command, it really shows that it is writing on to the chip.
The Programming Pages will increment form 0000 to 0007.
Programming Page: 0007 at address: 0x00070000

I am attaching the hexdump files.

root@example:/home/kiran/bios_files# flashrom -w Dec26_Bios
Calibrating delay loop... ok
No LinuxBIOS table found.
Found chipset "VT8237": Enabling flash write... OK.
SST49LF004A/B found at physical address: 0xfff80000
Flash part is SST49LF004A/B (512 KB)
Flash image seems to be a legacy BIOS. Disabling checks.

Erasing Flashrom:
-----------------------------
root@example:/home/kiran/bios_files# flashrom -E
Calibrating delay loop... ok
No LinuxBIOS table found.
Found chipset "VT8237": Enabling flash write... OK.
SST49LF004A/B found at physical address: 0xfff80000
Flash part is SST49LF004A/B (512 KB)
Erasing flash chip

It is showing the above message as if it is doing it. But I think no writes are happening and
only read is happening.

Thanks,
Kiran.

The same to you.

So how do they differ?

Can you tell if any writes to the flash chip worked - including the
erase?

You can use xxd to get a hex dump of the files, and then do diff -u
on those.
