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 14 Dec '18

14 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/

Building on Windows with mingw
by Miklos Marton 28 Feb '18

28 Feb '18

Hello all, I have tried to build the flashrom with mingw on Windows, but the build process fails with: flash.h:336:1: error: '__MINGW_PRINTF_FORMAT' is an unrecognized format function type [-Werror=format=] __attribute__((format(__MINGW_PRINTF_FORMAT, 2, 3))); I have checked the stdio.h shipped with the mingw installation, but it does not contains the __MINGW_PRINTF_FORMAT macro. I have used the latest available mingw-get-setup, because the 20110530 version (which mentioned in the wiki as known t obe working) segfaults when I select the MSYS Basic System feature. I can build with WARNERROR=no, but some more permanent fix recommentation would be warmly welcome! -- Best regards, Miklos Marton

Github PRs
by Miklos Marton 30 Jan '18

30 Jan '18

Hello flashrom developers! I have submitted two PRs to github (as the wiki mentions it is also a possible contribution channel). Do I need to do anything else with that? I am not intended to seems to be impatient I just would like to make sure that everything is in place (this is my first contribution to flashrom this way). If I remember correctly the coreboot gerrit was used to do code review. Is it going to be moved there or we will perform the code review at the github? -- Best regards, Miklos Marton

What's the intended license for flashrom?
by Nico Huber 29 Jan '18

29 Jan '18

Hi folks, I've just noticed that most of flashrom is licensed under GPLv2 + any later version, while about a third of the code base is GPLv2 only. I wonder if that is intentional, or if any of the license headers was just copy pasted and spread too much? Does somebody know any previous discussion on the topic? Nico

x1 Carbon 1st Gen Boots to Black Screen
by realraw＠tuta.io 27 Jan '18

27 Jan '18

Followed the coreboot wiki entry perfectly, and had no issues reading the flash chip. The 4MB Bios chip in my x1 differs from the Wiki Entry: Found Micron/Numonyx/ST flash chip "N25Q032..3E" (4096 kB, SPI) on linux_spi. Not sure if that impacts anything, however booting I am faced with a Black Screen. Fan is not running at all, and appears nothing is happening. I found this link as well: http://coreboot.coreboot.narkive.com/zUOsG1zN/lenovo-x1-carbon-3460-screen-… Flashed the rom at the end of the suggested mailing list comment, and still black screen. I have included the vbios in my build, so I'm not sure what's wrong. -realraw

Re: [flashrom] ERASE FAILED on Macronix Bios Chip x220 (Expected 0xff, Found=0x5a)

Hi realraw, you dropped the mailing list in your reply; by accident, I assume. On 27.01.2018 11:01, realraw(a)tuta.io wrote: > The stock bios is currently set at 1.40 and I decided I was going to try > to update to the latest BIOS.

The ME is a microcontroller built into the chipset. You always have to assume that it's running while you flash externally, so it's not unlikely that it gets confused. > > I believe the BIOS has some sort of write protection on, that will not > allow me to erase the BIOS.

Removing the chip to flash, should always work, though. I don't see any reason to swap the chip. > > My setup is the Pomona SOIC 8 Pin clip, female to female jumpers and the > RPi3.

I figured it now from the subject line. I little hidden, IMHO. You should always mention what you are trying to do in the email's body. I'm confident that your problem is not related to any write-protection (nobody else run into such issues with an X220, AFAIK). There are basi- cally two ways to flash an X220: 1. Remove all power (battery + AC) from the board and power the flash chip over the clip. This is generally discouraged unless you know exactly that the other chips on your board are protected against powering up as well (some ThinkPads have a diode on the VCC trace to the flash chip for that). You connect VCC to the clip in this case. 2. Wake-on-LAN state: Use the regular AC to power the board but keep the machine shut down. In this state a lot of components on the board are already active, including the flash chip. Do not attach VCC through the clip, if you do this! I would generally recommend 2. if you have a multimeter and can check that the flash chip is indeed powered. When you attach a network cable you can also see if the LEDs at the ethernet port light up, but this is no 100% reliable indication. Last but not least, the flash chip has two pins /HOLD and /WP that should be pulled up (to VCC). The mainboard should already take care of that, but you should check with a multimeter if that is the case. If not, or if you can't verify it, you should pull these two pins high. Hope that helps, Nico
