However, we will add the new names to the in-program (and hence wiki) database so that this new information becomes public. Thanks for the heads up, Victor. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

80/100/132 column line width policy
by Carl-Daniel Hailfinger 15 Dec '18

15 Dec '18

Hi, we're hitting the 80 column limit in our code in ways which actually reduce readability for the code. Examples are various multiline messages and complicated nested code where refactoring to a separate function doesn't make sense. Keeping the old 80 column limit is not really an option anymore. Standard terminal sizes have one of 80, 100 or 132 columns. Given the monitor resolutions many people have nowadays, I think it is safe to say that you can fit two xterms with 100 columns horizonally next to each other. 100 columns should also be sufficient for a msg_p* of roughly 80 columns of text. 132 columns provide more leeway, but IMHO that would be too wide for good readability (and my screen can't fit two xterms side-by-side anymore). Of course some files have sections where any column limit is not acceptable (board lists etc.), but the column limit violations should be limited to the affected file sections, not whole files. Comments? I'd like to get this decided today or tomorrow so we know where we need line breaks in Stefan Tauner's new struct flashchip patch. Regards, Carl-Daniel -- http://www.hailfinger.org/

FOSDEM Hardware Enablement Devroom
by Paul Kocialkowski 04 Dec '18

04 Dec '18

A Hardware Enablement devroom will be taking place at FOSDEM this year, on Sunday 10 December 2017. This newly-created devroom is the result of 3 proposals that were merged together. It is co-organized by several individuals. The devroom covers all aspects related to hardware enablement and support with free software, including aspects related to boot software, firmwares, drivers and userspace tools and adaptation. Proposals for talks related to these topics are welcome and can be submitted until Sunday 26 November 2017 via the pentabarf interface. Short talks are encouraged over longer ones in order to cover a wide range of topics. The announcement for the devroom, that contains all the useful information, was published at: https://lists.fosdem.org/pipermail/fosdem/2017-October/002649.html Cheers and see you at FOSDEM! -- Paul Kocialkowski, developer of free digital technology and hardware support Website: https://www.paulk.fr/ Coding blog: https://code.paulk.fr/ Git repositories: https://git.paulk.fr/ https://git.code.paulk.fr/

Is there anything I can do with this? Hi Yang, It sounds like your Bus Pirate is backpowering other electronics on the board (e.g. an embedded controller), which in turn try to access the SPI flash and interfere. This happens when the vendor does not isolate the SPI flash circuitry. Determine what other electronics might be powered by the Bus Pirate and see if you can hold them in reset so that they don't try to access the SPI flash.

how to have a log from the program

Hi, i'm using a ch341a programmer to flash my motherboard bios with your program, but i have the followin error: flashrom v0.9.9-97-g29333a0 on Windows 6.2 (x86) flashrom is free software, get the source code at https://flashrom.org Calibrating delay loop...

Fail to flash W25X40

Hi, I'm trying to rewrite a W24X40AL flash on a Seagate hard drive motherboard. I can successfully read the data, although some weird things happened. (First dumped code is nonsense, second time works fine, third or the rest are just partial corrupted code). Then I want to flash the code back but get the following error, parallels@ubuntu:~/Desktop$ sudo flashrom -p buspirate_spi:dev=/dev/ttyUSB0,spispeed=2M -E flashrom on Linux 4.4.0-59-generic (x86_64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).

Looking for another erase function. No usable erase functions left. FAILED! Your flash chip is in an unknown state. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks! My connection right now is: the motherboard is not powered, using bus pirate 3.3v directly connects to VCC, /WP and /HOLD. I've tried to add 10k, 20k resistor between 3.3v and /WP, /HOLD pin but the chip won't be recognized then. I don't have much experience in electronics. Is this do with write protection? Is there anything I can do with this? Thanks for your help. Yang Hu

Re: [flashrom] Update bios (not full flash) with flashrom
by Mike Banon 30 May '18

It could be that a manufacturer has released the same motherboards with two various sizes of a BIOS chip. You could try padding your 256 KB image with FF's to increase its' size up to 512 KB and then flash to the chip, after making a full backup ofcourse. Also you could look through your existing backup, to see how much of your 512 KB image is really occupied with anything thats not FF's, especially at the end. Could use some simple hex editor like Okteta to quickly check this On Tue, May 29, 2018 at 10:45 PM, Skoll RC <amisbievre(a)hotmail.fr> wrote: > I have an external programmer and a full backup of my current bios. nothing > writen, there was a label but it had to come off with time. > How can I concatenate images?

I have an external programmer and a full backup of my current bios. nothing writen, there was a label but it had to come off with time. How can I concatenate images? The update is not a full bios, is it? ________________________________ De : David Hendricks <david.hendricks(a)gmail.com> Envoyé : mardi 29 mai 2018 19:19 À : Skoll RC Cc : flashrom(a)flashrom.org Objet : Re: [flashrom] Update bios (not full flash) with flashrom On Sun, May 27, 2018 at 11:44 AM, Skoll RC <amisbievre(a)hotmail.fr> wrote: > Hi everyone, > > I would like to update my GA-8I915P-MF's bios with flashrom but Gigabyte > only provide updates and no full bios so when I try to update with > flashrom -p internal -w 8i9pmf.f2 I have an error message: Error: Image size > (262144 B) doesn't match the flash chip's size (524288 B)! > How can I fix it? That's unfortunate. Do you have an external programmer (something like a buspirate) that can be used in case things go wrong? Can you tell if there is anything written to the lower half of the chip? It could be as simple as concatenating the 256KB image to itself to create a 512KB image. But I wouldn't recommend trying that unless you have a good means of recovering.

27 May '18

Hi everyone, I would like to update my GA-8I915P-MF's bios with flashrom but Gigabyte only provide updates and no full bios so when I try to update with flashrom -p internal -w 8i9pmf.f2 I have an error message: Error: Image size (262144 B) doesn't match the flash chip's size (524288 B)! How can I fix it? thx
