Ibex Peak hangs
by John 16 Nov '10

16 Nov '10

Here is my lspci: http://flashrom.pastebin.com/4zVD3z7S When attempting to read, the chipset is not detected. After editing chipset_enable.c, changing the "3b00" in '{0x8086, 0x3b02, NT, "Intel", "3400 Desktop", enable_flash_ich10}' to "3b02", the following is output, followed immediately by a hard freeze: http://flashrom.pastebin.com/jNBdZ4YC "sudo ./flashrom -VV -c SST25VF016B" output: http://flashrom.pastebin.com/UA4vBm52 After applying this patch: http://patchwork.coreboot.org/patch/1532/ the output of "sudo ./flashrom -VV -c SST25VF016B" is: http://flashrom.pastebin.com/rCEgShPk And the output of "sudo ./flashrom -VV" was another freeze and output identical to: http://flashrom.pastebin.com/jNBdZ4YC Carldani said to mention that "flashrom hangs the machine on RES/REMS probe after you add an ich10 chipset enable for PCI ID 8086:3b02". -- http://www.fastmail.fm - mmm...

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

#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] Move implicit erase out of chip drivers, clean up
by Carl-Daniel Hailfinger 08 Oct '10

08 Oct '10

flashrom had an implicit erase-on-write for most flash chip and programmer drivers, but it was not entirely consistent. Some drivers had their own hand-rolled partial update functionality which made handling partial updates from generic code impossible. Move implicit erase out of chip drivers, clean up the chip write functions at the same time. A full chip erase is now performed in the generic code for all flash chips on write, and after that the whole chip is written. This is needed before we can change write function signature of the write functions to take start+len. Side note: With this patch and one or two followup patches, more functions will be easily recognizable as duplicates and can be eliminated. Compile tested and proofread, but that's it. The patch may cause flashrom to eat your dog or it may cause your dog to eat burned flash chips. Please test on real hardware. Thanks!

[PATCH] Note to add the board/device name to the subject when contacting the ML.
by Paul Menzel 08 Oct '10

08 Oct '10

A lot of messages sent to flashrom(a)flashrom.org just have »flashrom -V« as the subject rendering it in my opinion unusable. Adding the board/device name to the subject would help a lot when skimming over the messages by the subject line or searching the messages just using the subject line. • I did not add that note to outputs saying to report a bug to the mailing list. • I do not know if the subject line can be created automatically in those message, so users just have to copy and paste them. • I am not a native speaker, so I do not know if using plain »subject« instead of »subject line« would be enough and if the propositions I used are correct.

[PATCH] Board enable for Dell OptiPlex GX1 (try 2)
by Mattias Mattsson 05 Oct '10

05 Oct '10

Add board enable for Dell OptiPlex GX1. This is a new version of an earlier patch. - Change matching PCI ID:s to ethernet and north bridge. - Truncate board name to "OptiPlex GX1" as this patch probably apply to the whole series (they share the same vendor BIOS download). - Add URL to print.c - Marked board as OK. This was tested with an earlier version of flashrom (r1092), but nothing has changed that affects this patch (GPO30 is still always available on PIIX4). lspci output: http://www.flashrom.org/pipermail/flashrom/2010-July/004042.html Signed-off-by: Mattias Mattsson <vitplister(a)gmail.com> Thanks! -mattias

Tested on an MS-6163 Pro. This board has the same DMI-string and board enable as the "BX Master". (Confirmed by downloading and taking apart the vendor BIOS.) lspci output: http://www.flashrom.org/pipermail/flashrom/2010-August/004461.html Thanks, -mattias

Hi, I did some speed test on 4MB SPI flash: read: spipgm 2:41 flashrom 2:44 erase spipgm 0:21 flashrom 3:34 So you can see the read speed has improved :) Martin > > Great. Please note that the parameter changed from > > -p rayer_bitbang_spi > > to > > -p rayer_spi > > because the short form is faster to type, and users do not care at all > > about bitbanging.
