FAILED: MZ42-G20
by Keno Fischer 05 Nov '21

05 Nov '21

I tried to update the BIOS firmware on this board (the GIGABYTE MZ242-G20 in a G292-Z40 chassis) using `flashrom -pinternal`. This did not work, as it failed to find an appropriate erase function. I subsequently re-flashed using the BMC, which recovered the machine. Investigating the .bin files at the various stages, it appears that the erase did actually work, except that regions below 0x01000000 always read back as 0xFF under flashrom (while a proper SPI readback over the BMC shows this not to be the case). This board is an AMD Zen3 mainboard so the flasher in question is sb600. Looking at the image, I believe the regions above and below 0x01000000 are used as part of a dual bios setup, as they are substantially identical. Perhaps there are some protection registers in the SPI bus master that flashrom needs to be aware of in order to properly read this SPI flash? Keno

Truncating flash for oversized image
by Rob Shore 01 Nov '21

01 Nov '21

Hello! I've just discovered Flashrom as a way to use a Dediprog SPI programmer with MacOS, which is awesome. I've got a bit of a strange question though: I've got a 1Mbit rom on a board, but the image I was given for it is for a 2Mbit part. The firmware itself in the raw image is < 1Mbit, but the file is still larger than my ROM. Flashrom won't run the flash saying "Error: Image size (262144 B) doesn't match the flash chip's size (131072 B)!", which is technically correct. Is there a way to force the flash, and just have the process end after the first 131072B, which would result in the data I need being on the ROM? Thanks, and looking forward to using this tool some more! --Rob

Reading from multiple die stacked NAND flssh memory with flashrom
by s3th_0x 29 Oct '21

29 Oct '21

Hi all, I'm interested in reading from a Winbond's NAND Flash Memory W25M02GV <https://www.winbond.com/resource-files/W25M02GV%20Rev%20I%20051721.pdf>, but unfortunately flashrom does not support this chip yet. There are few differences between this chip and those already available in the flashchips.h from Winbond. It uses a SpiStack technology, which means stacking multiple die in one, in this case two nand 1G each. The ID for this nand is W25N01GV <https://www.winbond.com/resource-files/W25M02GV%20Rev%20I%20051721.pdf>. Actually the W25M02GV <https://www.winbond.com/resource-files/W25M02GV%20Rev%20I%20051721.pdf> is composed by two W25N01GV <https://www.winbond.com/resource-files/W25M02GV%20Rev%20I%20051721.pdf> NAND. this chip, for almost every instruction, has one or more dummy bytes after the instruction. This feature seems not to be implemented in any chip currently listed in flashrom. Also, my fault, I admit that I don't fully understand all the differences that could be hidden in having more than one die (perhaps more than the ones I mentioned above), and consequently the implications that it could entail in the implementation. I hope someone will be interested in developing this ability and can help me. Thanks, s3th0x References: Datasheet: https://www.winbond.com/resource-files/W25M02GV%20Rev%20I%20051721.pdf Linux Kernel MTD: https://elixir.bootlin.com/linux/latest/source/drivers/mtd/nand/spi/winbond… Arduino Library: https://github.com/squaresausage/WinbondW25N

Adding write protect/lock support to flashrom
by ln2＠mailo.com 18 Oct '21

18 Oct '21

Hi all, I would like to see the following feature added to flashrom: https://github.com/flashrom/flashrom/issues/185 If someone implemented it, would the idea (at least) be accepted? Is anyone interested in implementing it and claiming the $100 bounty? Text of the issue, for people too lazy to click: Some chips require certain bits (and similar features) be set before the hardware write-protect pins can be used. Flashrom doesn't currently support setting these bits, which makes it impossible to e.g hardware write-protect a BIOS chip after flashing Coreboot. I would like to see Flashrom add support for this. Attached is a patch which was written by someone else (they can identify themselves if they like) to toggle the relevant bits for a particular flash chip, each time flashrom is run, and tell the user what's going on. Your task, if you want to claim the bounty, is to: 1- Add some UI sugar so that the user can choose to set the appropriate bits (or not), and any other "features" needed to enable hardware write-protect, via the command line 2- Ensure the necessary bits and features can be set for a specified set of chips (see below), so Flashrom supports hardware write protect for at least all of the listed chips, and 3- Get your patch accepted and merged (it may be wise to first check with the maintainers that they are willing to add this feature) using Gerrit or the mailing list as per the official process If $100 isn't enough to make this attractive, I am open to increasing the bounty. I am also happy to escrow it if need be. Payment will be in Bitcoin.
