asus p2b - successful erase and write
by Branden Waldner 05 Jan '19

05 Jan '19

I got an asus p2b to go with my asus p2-99 for coreboot testing and it works with flashrom. Erase and write are reported as untested, so attached are logs of flashing from the award bios and from coreboot. It reports failure when trying erase function 0, but tries erase function 1 and works. It also requires the this_is_not_a_laptop option to work with the award bios. I can do any further testing or supply logs if required.

Hello, I noticed that "winbond" flash W25Q256.V is marked as UNTESTED. I tested read and write functions and they work correct. I was able to fire up board after re flashing with Amontech JTAGkey2 programmer. Attaching some prove. Good day! [image: image.png] [image: image.png] [image: image.png]

Flashrom for DOS?
by Woockash O 02 Jan '19

02 Jan '19

Hi, I am trying to flash my BIOS chip in Wyse SX30 thin client with Coreboot image. According to various articles, flashrom should be able to do that. However SX30 doesn't like most linux distributions (due to problems with BIOS that should be fixed after flashing the chip). I would like to try flashing it with flashrom release for DOS (freedos seems to work with no issues). However for some reason I am not able to access your buildbot website (tried on several browsers and networks). I have found only an old release (0.9.4) on another website. If there are any issues with buildbot site, could you please point me to the location where I can get some newer releases for DOS (at least 0.9.8)? Thanks Luc

One person already told me that I needed to use Gerrit, When we switched to Gerrit, we decided to still allow patches per email and also on GitHub. Though, all patches have to go through Gerrit in the end as that's where the official repository is. I've never been active on GitHub (my account is only few months old). And the developers that set the flashrom mirror up there obviously had the best intentions (pull requests are mentioned in the project des- cription) but aren't actively reviewing atm. I also can't say anymore that everything on Gerrit gets a review, though smaller changes do. If you'd use Gerrit, you'd hit the remaining active reviewers right in their everyday workflow. > but I'm not overly keen on learning a new process if I can avoid it. > Feedback welcome, thanks. I just tried, it was horrible ;) I just can't find a way to comment on individual commits of your PR (beside commenting inline in the code). I'll leave some comments their and pull those commits that seem ready to go. Nico

Flashing Asus KGPE-D16 Chip
by Joshua Aspinall 02 Jan '19

02 Jan '19

Hi, I am attempting to write a Libreboot ROM to my BIOS chip. The chip reports as follows: sudo flashrom -p linux_spi:dev=/dev/spidev0.0 'Found Winbond flash chip "W25Q16.V" (2048 kB, SPI) on linux_spi.' All of the online guides show reading the chip before attempting to flash, and confirming that the checksums match. However, when reading the contents of the flash chip, the checksums vary wildly. When attempting to flash the chip with a Libreboot ROM for the board, the erase function fails on all attempts as follows: sudo flashrom --programmer linux_spi:dev=/dev/spidev0.0 --write kgpe-d16_ukqwerty_txtmode.rom flashrom p1.0-141-g9cecc7e on Linux 4.14.79+ (armv6l) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).

I am trying to determine whether I am doing something incorrectly, or whether the chip is unserviceable and needs to be replaced. Any help/hints would be greatly appreciated!

Successful flash of ASRock soldered BIOS via BIOS_PH header
by David Bartley 30 Dec '18

30 Dec '18

I have an ASRock Z390M-ITX/ac motherboard with a soldered/non-removable BIOS chip (this is apparently not uncommon on ASRock motherboards). I initially tried using test clips, but I wasn't able to get a good connection. Fortunately, the motherboard features a BIOS_PH header that is wired to the BIOS chip. Despite existing on multiple motherboards, its pinout is seemingly only documented in the J3355M manual ( http://asrock.pc.cdn.bitgravity.com/Manual/J3355M.pdf). Using this pinout, I was able to connect some jumpers from the BIOS_PH header to a CH341A programmer and successfully read from and write to the chip (a W25Q128JVSIQ in my case). For reference, the BIOS_PH pinout (corresponding to a 25xx chip) is: DI | GND CLK | no connection no pin | DO VCC | CS HOLD | WP
