#123: layout file -------------------------------------+-------------------------------------- Reporter: vivanov@… | Owner: somebody Type: defect | Status: new Priority: major | Milestone: flashrom v1.0 Component: flashrom | Version: v2 Keywords: layout address offset | Dependencies: Patchstatus: there is no patch | -------------------------------------+-------------------------------------- Hello,
I am trying to update the BIOS "ST M50FW080" and get the following incomprehensibility - layout file works in a strange way 1) saved the current BIOS
{{{ $ flashrom --read flash18_saved.rom }}}
2) then I filled first 512K of this file with zeros (it is needed because new BIOS will have 512K size) 3) then I created rom.layout file to use the normal image only:
{{{ 00000000:0007ffff stuff 00080000:000fffff normal }}}
4) and started to upgrade BIOS
{{{ $ flashrom --write --layout rom.layout --image flash18_saved.rom }}}
And get the following:
{{{ Looking for "normal"... found. Calibrating delay loop... OK. No coreboot table found. Found chipset "Intel ICH4/ICH4-L", enabling flash write... OK. Found chip "ST M50FW080" (1024 KB) at physical address 0xfff00000. === This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE Please email a report to flashrom@coreboot.org if any of the above operations work correctly for you with this flash part.

'''Next'''
I changed the rom.layout file like follows:
{{{ # cat rom.layout 00000000:00080000 stuff 00080000:000fffff normal }}}
and get the '''right''' behaviour:
{{{ # flashrom --write --layout rom.layout --image normal --verify flash18_saved.rom Looking for "normal"... found. Calibrating delay loop... OK. No coreboot table found.

Please explain me which rom layout I should use to update the last 512K of 1M BIOS?
