10To build the flashrom utility you need to have the following packages
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]11installed on your Linux system:

25 file is specified)
26 -v | --verify: verify flash against file

28 -V | --verbose: more verbose output
29 -c | --chip <chipname>: probe only for specified flash chip
30 -s | --estart <addr>: exclude start position
31 -e | --eend <addr>: exclude end postion

Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]37 If no file is specified, then all that happens
38 is that flash info is dumped and the flash chip is set to writable.

Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]42--------------------------------------------
Ronald G. Minnich5e5f75e2002-01-29 18:21:41 +0000[diff] [blame]43
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]44Flashrom reads the LinuxBIOS table to determine the current mainboard.
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]45(Parse DMI as well in future?) If no LinuxBIOS table could be read
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]46or if you want to override these values, you can specify -m, e.g.:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]47
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]48 flashrom -w --mainboard ISLAND:ARUMA island_aruma.rom

Mondrian Nuessleaef1c7c2007-05-03 10:09:23 +0000[diff] [blame^]50The following boards require the specification of the board name, if
51no LinuxBIOS table is found:
52
53* IWILL DK8-HTX: use -m iwill:dk8_htx
54* agami Aruma: use -m AGAMI:ARUMA

Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]57ROM Layout Support
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]58------------------
59
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]60Flashrom supports ROM layouts. This allows to flash certain parts of
61the flash chip only. A ROM layout file looks like follows:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]62
63 00000000:00008fff gfxrom
64 00009000:0003ffff normal
65 00040000:0007ffff fallback
66
67 i.e.:
68 startaddr:endaddr name
69
70 all addresses are offsets within the file, not absolute addresses!
71
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]72If you only want to update the normal image in a ROM you can say:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]73
74 flashrom -w --layout rom.layout --image normal island_aruma.rom
75
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]76To update normal and fallback but leave the VGA BIOS alone, say:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]77
78 flashrom -w -l rom.layout -i normal -i fallback island_aruma.rom
79
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]80Currently overlapping sections are not supported.
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]81
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]82ROM layouts should replace the -s and -e option since they are more
83flexible and they should lead to a ROM update file format with the
84ROM layout and the ROM image in one file (cpio, zip or something?)

90DISK on Chip support is currently disabled since it is considered unstable.
Stefan Reinauercbc55d02006-08-25 19:21:42 +0000[diff] [blame]91Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.
