Hi,
I just tried to flash bios in nvidia p106-100 with. But I get errors :
sudo flashrom --programmer ch341a_spi -w p106v.rom flashrom v1.2 on Linux 5.15.0-46-generic (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 Winbond flash chip "W25Q40EW" (512 kB, SPI) on ch341a_spi. Reading old flash chip contents... done.

Looking for another erase function. Looking for another erase function. Looking for another erase function. No usable erase functions left. FAILED! Uh oh. Erase/write failed. Checking if anything has changed. Reading current flash chip contents... done. Apparently at least some data has changed. Your flash chip is in an unknown state. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom@flashrom.org, thanks!
What to do next ?

note this is a 1.8V chip and that might be the cause of your problems. If you don't have a voltage adapter between your CH341A and the flash chip, a safety circuit in the flash will trigger and prevent erasing (as that would damage the chip at higher voltage).
If you already have a voltage adapter, it might be a write-protection. Make sure that all the input pins have a defined state and that the /WP pin is at a high level.
Hope that helps, Nico
Hi Nico, No, I dont have it...Didnt know that chip is 1.8v. ch341a support is 3.3-5v. I must find voltage contorler. Thaks, I will replay is that help :-) RegardsDelevic
