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/

Hello Matt, your mail never made it to the list, due to it's excessive size. Please don't send such huge attachments.

Yes, we recently added support for the next bigger version 25Q80EW, and I just pushed a patch for 25Q40EW [1]. With Git, you can fetch / apply it as follows: git fetch https://review.coreboot.org/flashrom refs/changes/62/25462/1 git cherry-pick FETCH_HEAD It's still untested, though.

Thanks for your help! Ok, this shows how rusty i am with respect to flashrom. Not recognizing the + 0x0C as the typical offset for intel gpio line toggle. What this board needs is a call to intel_ich_gpio20_raise(); Will provide a patch later today. I am a bit worried though that the lpc io BAR is empty in your lspci. I am not sure whether that is handled in any way, and i do not think the intel gpio code in flashrom will deal with an empty bar gracefully. Luc Verhaegen.

In situ Thinkpad E420 Sandy Bridge/Cougar Point PCH
by awokd 24 Mar '18

24 Mar '18

Having trouble getting a good read from a Macronix MX25L3206E in situ Thinkpad E420 Sandy Bridge/Cougar Point PCH. Don't believe it's a programmer problem because I used the same programmer and pinouts to successfully flash a Winbond W25Q32.V in a different system. I found the Wistron LLW-1/LGG-1 schematic and matched the flash chip up with the silk-screened label. Tried it in system with system power. I've pulled the board and RAM. Also tried removing CPU. Symptoms of the problem are: - On system power, doesn't detect chip. - Using an external PS, when I restrict the current to the point there's a vdroop to ~3.0v-3.2v, flashrom detects the chip. If I give it more current (at 3.3v), the chip disappears and flashrom no longer sees it. - Occasionally it acts like a successful read, WRSR updates correctly but resulting file is mostly FF with a section of pages of 00 and some with alternating bit patterns. Oddly, the file is consistent over multiple runs and diff reports no differences, but there is nothing in it that looks like actual data and ifdtool says there's no descriptor. Suspect the issue is as described on https://www.flashrom.org/ISP- that ME is getting powered and locking/hiding the chip. It suggests connecting the reset line to CS. Searching the schematic for RST results in numerous pages. How can I identify the right place to accomplish this, preferably without soldering? Alternatively, I see in the SPI programming guide there might be a couple other ways to disable ME? 1. Temporarily disable the Intel® ME through the MEBX. Power off or cold reset. - This option is only applicable to non-Intel ME Ignition firmware. 2. HDA_SDO(Manufacturing mode jumper or Flash descriptor override jumper) asserted HIGH on the rising edge of PWROK. Power off or cold reset. Note: this is only valid as long as you do not specifically set the variable Flash Descriptor Overrride Pin-Strap Ignore in the Flash Image Tool to false. I found #2 on the schematic with a not installed resistor (what does "DY" stand for anyways, "Damn You"?) but can't find the label for it on the motherboard and it looked like it would also need soldering beyond my capability. Any suggestions?

Re: [flashrom] Thinkpad T420
by Ivan Ivanov 22 Mar '18

Sorry for late reply. Yes, it looks like your connection is bad. Try using the shorter wires, and hopefully of a good quality ( e.g. pure copper wires could be 1.5 longer than the cheap aluminium wires and still have the same conductivity given the same internal thickness ) You have mentioned that you have updated the Bus Pirate firmware. To what version did you upgrade? I always recommend upgrading to the latest Bus Pirate community firmware (the old official one is dead) You could obtain it here - https://github.com/BusPirate/Bus_Pirate Alternatively, you may try a $3 very cheap CH341A USB programmer, which is also supported by flashrom project and has a much simpler hardware, i.e. it does not have the internal firmware, just a tiny EEPROM of 20 or 32 bytes size + 8 bit CFG register. The board of CH341A usb programmer is small and extremely simple, and the simplicity could be a key to success Best regards, Ivan 2018-03-17 14:31 GMT+03:00 <aadu(a)airmail.cc>: > > I apologise if I should write to flashrom mailing list instead and not you > directly. > > It was night when I wrote that message and I was tired.

Hello team Here's the output of flashrom on my machine, as well as my system information.

You seem to be running flashrom on an unsupported laptop. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility.

Can't Flash on AOpen i965GMt-LA motherboard
by Björn Tantau 19 Mar '18

19 Mar '18

Hi! I tried to flash a new BIOS to my AOpen i965GMt-LA motherboard. Reading the ROM worked, but flashing did not. I'll gladly give you more information, just tell me what you need. :-) Cheers, Björn $ sudo flashrom --programmer internal -c "W39V040FA" -w IGC1B.BIN flashrom v0.9.9-rc1-r1942 on Linux 4.4.0-112-generic (x86_64) flashrom is free software, get the source code at https://flashrom.org Calibrating delay loop... OK. Found chipset "Intel ICH8M". Enabling flash write... OK. Found Winbond flash chip "W39V040FA" (512 kB, FWH) mapped at physical address 0x00000000fff80000. Reading old flash chip contents... done. Erasing and writing flash chip... FAILED at 0x00000000! Expected=0xff, Found=0x49, failed byte count from 0x00000000-0x00000fff: 0x463 ERASE FAILED! Reading current flash chip contents... done.

No usable erase functions left. FAILED! Uh oh. Erase/write failed. Checking if anything has changed. Reading current flash chip contents... done. Good, writing to the flash chip apparently didn't do anything. This means we have to add special support for your board, programmer or flash chip. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks! ------------------------------------------------------------------------------- You may now reboot or simply leave the machine running.
