Re: [LinuxBIOS] Unable to flash the K8Upgrade-VM800 Bios

[Kiran Patil]

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

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.
