12.B flashrom
Uwe Hermanne8ba5382009-05-22 11:37:27 +000013is a utility for detecting, reading, writing, verifying and erasing flash
Uwe Hermann530cb2d2009-05-14 22:58:21 +000014chips. It's often used to flash BIOS/EFI/coreboot/firmware images in-system
Uwe Hermann941a2732011-07-25 21:12:57 +000015using a supported mainboard. However, it also supports various external
16PCI/USB/parallel-port/serial-port based devices which can program flash chips,
17including some network cards (NICs), SATA/IDE controller cards, graphics cards,
18the Bus Pirate device, various FTDI FT2232/FT4232H based USB devices, and more.
Uwe Hermanne74b9f82009-04-10 14:41:29 +000019.PP
Uwe Hermann9ff514d2010-06-07 19:41:25 +000020It supports a wide range of DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40,
Uwe Hermann941a2732011-07-25 21:12:57 +000021TSOP48, and BGA chips, which use various protocols such as LPC, FWH,
22parallel flash, or SPI.
Stefan Reinauer261144c2006-07-27 23:29:02 +000023.SH OPTIONS
Uwe Hermann9ff514d2010-06-07 19:41:25 +000024.B IMPORTANT:
Carl-Daniel Hailfinger5de93412009-05-01 10:53:49 +000025Please note that the command line interface for flashrom will change before
26flashrom 1.0. Do not use flashrom in scripts or other automated tools without
Uwe Hermanne8ba5382009-05-22 11:37:27 +000027checking that your flashrom version won't interpret options in a different way.
Carl-Daniel Hailfinger5de93412009-05-01 10:53:49 +000028.PP
Uwe Hermann9ff514d2010-06-07 19:41:25 +000029You can specify one of
30.BR \-h ", " \-R ", " \-L ", " \-z ", " \-E ", " \-r ", " \-w ", " \-v
31or no operation.
Carl-Daniel Hailfinger8841d3e2010-05-15 15:04:37 +000032If no operation is specified, flashrom will only probe for flash chips. It is
Michael Karcher31fd8252010-03-12 06:41:39 +000033recommended that if you try flashrom the first time on a system, you run it
Uwe Hermann941a2732011-07-25 21:12:57 +000034in probe-only mode and check the output. Also you are advised to make a
Uwe Hermann9ff514d2010-06-07 19:41:25 +000035backup of your current ROM contents with
36.B \-r
37before you try to write a new image.

Uwe Hermanne74b9f82009-04-10 14:41:29 +000039.B "\-r, \-\-read <file>"
40Read flash ROM contents and save them into the given
41.BR <file> .
Uwe Hermann941a2732011-07-25 21:12:57 +000042If the file already exists, it will be overwritten.
Stefan Reinauerde063bf2006-09-21 13:09:22 +000043.TP
Uwe Hermanne74b9f82009-04-10 14:41:29 +000044.B "\-w, \-\-write <file>"
Carl-Daniel Hailfinger8841d3e2010-05-15 15:04:37 +000045Write
46.B <file>
Uwe Hermann9ff514d2010-06-07 19:41:25 +000047into flash ROM. This will first automatically
48.B erase
49the chip, then write to it.
Stefan Taunerac54fbe2011-07-21 19:52:00 +000050.sp
51In the process the chip is also read several times. First an in-memory backup
52is made for disaster recovery and to be able to skip regions that are
53already equal to the image file. This copy is updated along with the write
54operation. In case of erase errors it is even re-read completely. After
55writing has finished and if verification is enabled, the whole flash chip is
56read out and compared with the input image.
Stefan Reinauerde063bf2006-09-21 13:09:22 +000057.TP
Uwe Hermannea07f622009-06-24 17:31:08 +000058.B "\-n, \-\-noverify"
Carl-Daniel Hailfinger8841d3e2010-05-15 15:04:37 +000059Skip the automatic verification of flash ROM contents after writing. Using this

Carl-Daniel Hailfinger8841d3e2010-05-15 15:04:37 +000062recommended, you should only use it if you know what you are doing and if you
Uwe Hermannea07f622009-06-24 17:31:08 +000063feel that the time for verification takes too long.
64.sp
65Typical usage is:
Uwe Hermann9ff514d2010-06-07 19:41:25 +000066.B "flashrom \-n \-w <file>"
Uwe Hermannea07f622009-06-24 17:31:08 +000067.sp
68This option is only useful in combination with
69.BR \-\-write .
70.TP
Uwe Hermanne74b9f82009-04-10 14:41:29 +000071.B "\-v, \-\-verify <file>"

Stefan Taunereebeb532011-08-04 17:40:25 +000080(max. 3 times, i.e.
81.BR \-VVV )

93.sp
94flashrom reads the coreboot table to determine the current mainboard. If no

Joerg Mayer645c6df2010-03-13 14:47:48 +0000115.TP
116.B "\-l, \-\-layout <file>"
117Read ROM layout from
118.BR <file> .
Uwe Hermann87c07932009-05-05 16:15:46 +0000119.sp
120flashrom supports ROM layouts. This allows you to flash certain parts of
121the flash chip only. A ROM layout file looks like follows:
122.sp
123 00000000:00008fff gfxrom
124 00009000:0003ffff normal
125 00040000:0007ffff fallback
126.sp
127 i.e.:
128 startaddr:endaddr name
129.sp
130All addresses are offsets within the file, not absolute addresses!
131If you only want to update the normal image in a ROM you can say:
132.sp
Uwe Hermann9ff514d2010-06-07 19:41:25 +0000133.B " flashrom \-\-layout rom.layout \-\-image normal \-w agami_aruma.rom"
Uwe Hermann87c07932009-05-05 16:15:46 +0000134.sp
135To update normal and fallback but leave the VGA BIOS alone, say:
136.sp
Uwe Hermann9ff514d2010-06-07 19:41:25 +0000137.B " flashrom \-l rom.layout \-i normal \"

246Otherwise, the mainboard is detected by examining the onboard PCI devices
Michael Karcher7f0c3ec2010-03-07 22:29:28 +0000247and possibly DMI info. If PCI and DMI do not contain information to uniquely
248identify the mainboard (which is the exception), it might be necessary to
Uwe Hermann9ff514d2010-06-07 19:41:25 +0000249specify the mainboard using the
250.B \-m
251switch (see above).

Uwe Hermann9ff514d2010-06-07 19:41:25 +0000253Some of these board-specific flash enabling functions (called
254.BR "board enables" )
Michael Karcher7f0c3ec2010-03-07 22:29:28 +0000255in flashrom have not yet been tested. If your mainboard is detected needing
256an untested board enable function, a warning message is printed and the
257board enable is not executed, because a wrong board enable function might
258cause the system to behave erratically, as board enable functions touch the
259low-level internals of a mainboard. Not executing a board enable function
260(if one is needed) might cause detection or erasing failure. If your board
261protects only part of the flash (commonly the top end, called boot block),
262flashrom might encounter an error only after erasing the unprotected part,
263so running without the board-enable function might be dangerous for erase
264and write (which includes erase).
265.sp
266The suggested procedure for a mainboard with untested board specific code is
267to first try to probe the ROM (just invoke flashrom and check that it
268detects your flash chip type) without running the board enable code (i.e.
Uwe Hermann9ff514d2010-06-07 19:41:25 +0000269without any parameters). If it finds your chip, fine. Otherwise, retry
Michael Karcher7f0c3ec2010-03-07 22:29:28 +0000270probing your chip with the board-enable code running, using
271.sp
Uwe Hermann9ff514d2010-06-07 19:41:25 +0000272.B " flashrom \-p internal:boardenable=force"
Michael Karcher7f0c3ec2010-03-07 22:29:28 +0000273.sp
274If your chip is still not detected, the board enable code seems to be broken
275or the flash chip unsupported. Otherwise, make a backup of your current ROM
Uwe Hermann9ff514d2010-06-07 19:41:25 +0000276contents (using
277.BR \-r )
278and store it to a medium outside of your computer, like
279a USB drive or a network share. If you needed to run the board enable code
Michael Karcher7f0c3ec2010-03-07 22:29:28 +0000280already for probing, use it for reading too. Now you can try to write the
281new image. You should enable the board enable code in any case now, as it
282has been written because it is known that writing/erasing without the board
283enable is going to fail. In any case (success or failure), please report to
284the flashrom mailing list, see below.

Carl-Daniel Hailfinger27023762010-04-28 15:22:14 +0000286On systems running coreboot, flashrom checks whether the desired image matches
287your mainboard. This needs some special board ID to be present in the image.

289do not match, it will refuse to write the image unless you specify

650Using flashrom on laptops is dangerous and may easily make your hardware
651unusable unless you can desolder the flash chip and have a full flash chip
652backup. This is caused by the embedded controller (EC) present in many laptops,
653which interacts badly with any flash attempts. This is a hardware limitation
654and flashrom will attempt to detect it and abort immediately for safety reasons.
