Hello all ............
we are working on the coreboot project ..... Initially we are copied the BIOS(PM49FL004) content that is present in the motherboard( ASRock K8Upgrade-VM800) in a file name called jan-14 and tried to flash(write) the content in the filename jan-14 on to a new flashrom SST49LF004B.. but flash is not happened properly .. these are the steps we followed ... [EMAIL PROTECTED] flashrom]# flashrom Calibrating delay loop... OK. No LinuxBIOS table found. Found chipset "VT8237", enabling flash write... OK. generic_spi_command called, but no SPI chipset detected Pm49FL004 found at physical address 0xfff80000. Flash part is Pm49FL004 (512 KB). No operations were specified. *Reading the original Bios content in to the file jan14:* [EMAIL PROTECTED] flashrom]# flashrom -r jan14 Calibrating delay loop... OK. No LinuxBIOS table found. Found chipset "VT8237", enabling flash write... OK. generic_spi_command called, but no SPI chipset detected Pm49FL004 found at physical address 0xfff80000. Flash part is Pm49FL004 (512 KB). Reading Flash...done [EMAIL PROTECTED] flashrom]# flashrom -v jan14 Calibrating delay loop... OK. No LinuxBIOS table found. Found chipset "VT8237", enabling flash write... OK. generic_spi_command called, but no SPI chipset detected Pm49FL004 found at physical address 0xfff80000. Flash part is Pm49FL004 (512 KB). Flash image seems to be a legacy BIOS. Disabling checks. Verifying flash... VERIFIED. ***Then we removed the original Bios chip and inserted the new flashrom SST49LF004B and tried to flash(write) the content present in the filename jan14 ,but finally we got the result as bellow ........ *Writing on to the new Bios chip (SST49LF004B):* [EMAIL PROTECTED] flashrom]# flashrom -w jan14 Calibrating delay loop... OK. No LinuxBIOS table found. Found chipset "VT8237", enabling flash write... OK. generic_spi_command called, but no SPI chipset detected SST49LF004A/B found at physical address 0xfff80000. Flash part is SST49LF004A/B (512 KB). Flash image seems to be a legacy BIOS. Disabling checks. Programming page: 0007 at address: 0x00070000 *Then we varified .....* [EMAIL PROTECTED] flashrom]# flashrom -v jan14 Calibrating delay loop... okNo LinuxBIOS table found.Found chipset "VT8237": Enabling flash write... OK.SST49LF004A/B found at physical address: 0xfff80000Flash part is SST49LF004A/B (512 KB)Flash image seems to be a legacy BIOS. Disabling checks.Verifying flash - FAILED So we tried to change the flashrom utility code..so first we downloaded coreboot code from the coreboot.org then in that we tried to change the code in util/flashrom file but stil we are unable to get the way where we need to change the code such that the flash can happen ... we are also gone through the datasheet of SST49LF004B and PM49FL004 but we are not getting any exact idea ....... please guide us............... with regards, lalitha
