| Flashrom README |
| ------------------------------------------------------------------------------- |
| |
| Flashrom is a universal flash programming utility for DIP, PLCC, or SPI |
| flash ROM chips. It can be used to flash BIOS/coreboot/firmware images. |
| |
| (see http://coreboot.org for details on coreboot) |
| |
| |
| Build Requirements |
| ------------------ |
| |
| To build the flashrom utility you need to have the following packages |
| installed on your Linux system: |
| |
| * pciutils |
| * pciutils-devel / pciutils-dev |
| * zlib-devel / zlib1g-dev |
| |
| |
| Usage |
| ----- |
| |
| $ flashrom [-rwvEVfh] [-c chipname] [-s exclude_start] [-e exclude_end] |
| [-m [vendor:]part] [-l file.layout] [-i imagename] [file] |
| -r | --read: read flash and save into file |
| -w | --write: write file into flash (default when |
| file is specified) |
| -v | --verify: verify flash against file |
| -E | --erase: erase flash device |
| -V | --verbose: more verbose output |
| -c | --chip <chipname>: probe only for specified flash chip |
| -s | --estart <addr>: exclude start position |
| -e | --eend <addr>: exclude end postion |
| -m | --mainboard <[vendor:]part>: override mainboard settings |
| -f | --force: force write without checking image |
| -l | --layout <file.layout>: read rom layout from file |
| -i | --image <name>: only flash image name from flash layout |
| |
| If no file is specified, then all that happens |
| is that flash info is dumped and the flash chip is set to writable. |
| |
| |
| coreboot Table and Mainboard Identification |
| -------------------------------------------- |
| |
| Flashrom reads the coreboot table to determine the current mainboard |
| (parse DMI as well in future?). If no coreboot table could be read |
| or if you want to override these values, you can specify -m, e.g.: |
| |
| flashrom -w --mainboard AGAMI:ARUMA agami_aruma.rom |
| |
| The following boards require the specification of the board name, if |
| no coreboot table is found: |
| |
| * IWILL DK8-HTX: use -m iwill:dk8_htx |
| * Agami Aruma: use -m AGAMI:ARUMA |
| * ASUS P5A: use -m asus:p5a |
| * IBM x3455: use -m ibm:x3455 |
| * EPoX EP-BX3: use -m epox:ep-bx3 |
| * GIGABYTE GA-M57SLI-S4 v2.0: use -m gigabyte:m57sli |
| * GIGABYTE GA-M61P-S3: use -m gigabyte:m61p |
| * MSI K8N Neo3: use -m msi:k8n-neo3 |
| * Acorp 6A815EPD: use -m acorp:6a815epd |
| |
| |
| ROM Layout Support |
| ------------------ |
| |
| Flashrom supports ROM layouts. This allows you to flash certain parts of |
| the flash chip only. A ROM layout file looks like follows: |
| |
| 00000000:00008fff gfxrom |
| 00009000:0003ffff normal |
| 00040000:0007ffff fallback |
| |
| i.e.: |
| startaddr:endaddr name |
| |
| All addresses are offsets within the file, not absolute addresses! |
| |
| If you only want to update the normal image in a ROM you can say: |
| |
| flashrom -w --layout rom.layout --image normal agami_aruma.rom |
| |
| To update normal and fallback but leave the VGA BIOS alone, say: |
| |
| flashrom -w -l rom.layout -i normal -i fallback agami_aruma.rom |
| |
| Currently overlapping sections are not supported. |
| |
| ROM layouts should replace the -s and -e option since they are more |
| flexible and they should lead to a ROM update file format with the |
| ROM layout and the ROM image in one file (cpio, zip or something?). |
| |
| |
| Disk on Chip support |
| -------------------- |
| |
| Disk on Chip support was removed from flashrom in r3382. It had already |
| been disabled by default in flashrom for several years because the code |
| was considered unstable and incomplete. The products intended to work |
| have been End-Of-Lifed by the manufacturer for a long time. |
