#1: flashRom doesn't work on MotherBoard with ICH9 + MP2532

by flashrom

#1: flashRom doesn't work on MotherBoard with ICH9 + MP2532 --------------------------------------------------+------------------------- Reporter: annyvonne.le_coq@… | Owner: hailfinger Type: defect | Status: new Priority: major | Milestone: flashrom 0.9.1 Component: flashrom | Version: Keywords: | Dependencies: Patchstatus: there is no patch | --------------------------------------------------+------------------------- Hi all, I have a mother board equipped with ICH9 chipset and M25P32 flash device. I can't use flashrom to re-program my BIOS. 1) The ICH9 is not recognized. So, I add its device ID (2910) in chipset_enable.c file. 2) Then, M25P32 flash device is recognized, but OPCODE 06 is not in the list OPCODESS OS_ST_M25P. ich_spi_command try to find the command 06 in the list, The list contains only following values: 2, 3, 216, 5, 171, 1, 159, 199. The M25P32 has been tested with flashrom. So, I imagine that the problem is due to the caller. Have you got an idea about this issue. Thanks Anne -- Ticket URL: <http://www.flashrom.org/trac/flashrom/ticket/1> flashrom <http://www.flashrom.org/>

[PATCH] new windows port

by Stefan Reinauer

Hi, I separated the direct io access code from the flashrom changes, to make this code easily available for the other coreboot utilities, too. The remaining windows patch is rather small. I'll clean up the directio code some more and make a release asap. Best regards, Stefan -- coresystems GmbH • Brahmsstr. 16 • D-79104 Freiburg i. Br.

[patch] add intel_piix4_gpo_set()

by Luc Verhaegen

This is code from a an old board enable that i sent in 3 weeks ago. This board enable was not necessary (as flashing worked just fine without it too). But this function was also used to clean up the board enable for the epox ep bx3. I have tracked down the person for whom i wrote this board enable 2 years ago: irc user nyu, aka Robert Millan. Robert, can you verify that this code is not a regression for you? Uwe, in the original mail thread (http://www.coreboot.org/pipermail/coreboot/2009-June/049789.html) you had several suggestions. I have taken over unsigned int and the bitshift, but i do mot like to put "PIIX4{,E,M}" everywhere. "PIIX4{,E,M}" all over clutters up the place, and i fear that printing this to the user will generate more confusion than it will ever remove. Instead i have adjusted the initial function comment to mention this so that developers can rest assured in future that this will also be valid for their future board enables. Luc Verhaegen.

[Patch] Shuttle AK31

by Luc Verhaegen

Resending this patch to the newly formed flashrom ml. Ron already kindly acked this patch. Mateusz, the owner of this board gave me a brief comment on irc stating that it didn't work. Which is also the last i heard from him. Mateusz, get back to us and get us at least the flashrom output. Luc Verhaegen.

[PATCH] Totally generic SPI chip match

by Carl-Daniel Hailfinger

If a chip is not on the RDID generic vendor list nor on the REMS specific ID list, flashrom will claim that no chip is there. Handle these cases gracefully. flashrom will ignore generic matches if a specific chip was found, so this will have no impact on supported chips, but help a lot for a first quick analysis by the user or developer. The only drawback is that unknown chips may be recognized multiple times until they are added to flashchips.[ch].

Fix feature detection when fdti requires libusb for linking

by Joerg Mayer

see attached patch. patch is too small to be copyrightable... ciao Joerg -- Joerg Mayer <jmayer(a)loplof.de> We are stuck with technology when what we really want is just stuff that works. Some say that should read Microsoft instead of technology.

flashing results for the MS-7094 board

by Jelle Geerts

Hello, I've ran flashrom -v {-E,-r,-v,-w} on my MS-7094 board. For more info regarding the board, please see http://www.msi.com/index.php?func=proddesc&maincat_no=1&cat2_no=&cat3_no=... I've attached the results to this e-mail. Reading/verifying/writing worked fine. Erasing however, didn't go so well, as you can see in the attached log. BTW, two thumbs up to the flashrom developers: the Award flash utility did not work (kept saying 'Unknown flash type'), but flashrom did. ;) HTH, Jelle Geerts

Non-working board submission: Asrock K7VT4A+

by Putlinuxonit

Hi, I've tested this board with flashrom-0.9.0-r695 as well as superiotool r4424. Also contained are dumps from* #lspci -vvnnxxxx*, *#dmidecode* and *#lshw*. i tried a forced read via *#flashrom -f -r -c SST39SF020A oldfirmware.bin*and provide the dumps as well though that maybe useless as i was warned. A lot of the info is probably duplicated but is provided for the sake of completeness. Bios: AMI > Board: Asrock K7VT4A+ > Flash Chip: SST39SF020A (PLCC) > Chipset: Via VT8235 > Enjoy!, Udu E.

[PATCH] Bitbanging SPI driver

by Carl-Daniel Hailfinger

This is a bitbanging SPI driver without hardware support. If you want support for a particular piece of hardware, just fill in a few functions. That's it. Tested, trace looks OK. Not 0.9.1 material.

[PATCH] Add -p gfxnvidia for flashing NVIDIA graphics cards

by Uwe Hermann

See patch. Please do NOT try write/erase on any important cards yet, it doesn't seem to fully work properly yet and you could "brick" your card. I tested a "RIVA TNT2 Model 64/Model 64 Pro", which successfully identified and read a Winbond W29C011 chip, but erase and write behaved incorrect and I finally bricked the card. Will look into recovery soon (likely will work via software I assume, no hardware hacking strictly required I think/hope, we'll see). As for the list of supported cards: I have no idea which of those may work (i.e. have the same flash programming interface), maybe none, maybe all of them (and lots more NVIDIA cards), we'll see as soon as others test more cards.
