SMBus revision 0x61 does not match known values
by Julian Labus 12 Oct '20

12 Oct '20

The flashrom program asked me to report this when I tried to check if my mainboard is supported. The mainboard is a Gigabyte X570 AORUS ELITE. $ sudo flashrom -p internal flashrom v1.2 on Linux 5.8.14-arch1-1 (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). Found chipset "AMD FP4". Enabling flash write... FCH device found but SMBus revision 0x61 does not match known values. Please report this to flashrom(a)flashrom.org and include this log and the output of lspci -nnvx, thanks!. Could not determine chipset generation.PROBLEMS, continuing anyway No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically.

Operating Systems for coreboot/flashrom/etc?
by Clay Daniels 12 Oct '20

12 Oct '20

I am a big FreeBSD fan, and also run NetBSD on an older machine. Haven't used much Linux lately but installed Ubuntu to get a lspci for flashrom use. Ubuntu is fine, but does not have superiotool available as best I see. Looking back to FreeBSD I found superiotool just where I expected, as a port to be compiled under sysutils. Works fine, but still never finds my hidden bios I will call "SPI1" for lack of a better name. Anyway, I keep looking for more tools, and have an extra disk drive for another OS if anyone has any good suggestions? Right now I'm in Ubuntu, listening to the coreboot & flashrom freenode IRC channels. Quite a lot goes on there if you catch it right. Some real sharp guys. Clay

Chip burner CH341A commands
by Hîj Vasile 12 Oct '20

12 Oct '20

Hi Flashrom, I have a PCB of a HDD which is damaged by heat, but I was trying to read the bios chip. I have tried with CH341a Programmer 1.29 and 1.41, but I cannot find my bios 25S40A 00 LFGC. I have tried second option with Ubuntu command (installed as a subsystem of Windows). So, I am using this command sudo flashrom --programmer ch341a_spi -r bCouldn't open device 1a86:5512. Error: Programmer initialization failed. It is a because I run Ubuntu as described, the cleat not touching the pins enough or my chip is burned too? I would appreciate any help. Kind regards, Vasile

[PATCH 1/2] meson: add missing need_raw_access
by Rosen Penev 12 Oct '20

12 Oct '20

Currently, when passing meson -Dconfig_rayer_spi=false , compilation fails as the proper headers and defines are not available.

[PATCH] sb600
by Rene Rebe 11 Oct '20

11 Oct '20

Added AMD Ryzen 3950x X570 and AMD Ryzen 4000 Mobile PCI revisions to AMD FP4 / AM4 sb600spi.c. Trying to use flashrom to downgrade my Asus WS X570 ACE bios to a previous, more stable and performant version I just got this output: flashrom -p internal flashrom v1.2 on Linux 5.8.13-dist (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). Found chipset "AMD FP4". Enabling flash write... FCH device found but SMBus revision 0x61 does not match known values. So I patched mine and a friends MSI Modern 14 Ryzen 4700 laptop revisions in and we could both read the BIOS and I also tested flashing the Asus WS X570 ACE succesfully.

Beginners-Guide-to-Using-a-CH-A-SPI-Programmer with AMD
by Clay Daniels 08 Oct '20

08 Oct '20

https://www.win-raid.com/t4287f16-GUIDE-The-Beginners-Guide-to-Using-a-CH-A… Nice article in general, but it also says: "*Note:* If you are flashing an AMD motherboard, you need to put the 1.8V adapter into the SPI, and then put the clip assembly onto that." So is this right? 3.3v for Intel, 1.8v for AMD?
