dev@mate:/tmp$ sudo flashrom -p internal --ifd -i bios -w coreboot.rom --noverify-all [sudo] Passwort für dev: flashrom v1.2 on Linux 5.15.0-40-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). No DMI table found. Found chipset "Intel Apollo Lake". Enabling flash write... Warning: BIOS region SMM protection is enabled! Warning: Setting Bios Control at 0xdc from 0xaa to 0x89 failed. New value is 0xaa. SPI Configuration is locked down. Enabling hardware sequencing because some important opcode is locked. PROBLEMS, continuing anyway ======================================================================== You may be running flashrom on an unknown laptop. We could not detect this for sure because your vendor has not set up the SMBIOS tables correctly. Some internal buses have been disabled for safety reasons. You can enforce using all buses by adding -p internal:laptop=this_is_not_a_laptop to the command line, but please read the following warning if you are not sure.
Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and https://flashrom.org/Laptops for details.
If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== Found Programmer flash chip "Opaque flash chip" (16384 kB, Programmer-specific) mapped at physical address 0x0000000000000000. Reading ich descriptor... done. Using region: "bios". Reading old flash chip contents... done. Erasing and writing flash chip... Transaction error between offset 0x00001000 and 0x00001fff (= 0x00001000 + 4095)! Reading current flash chip contents... done. Looking for another erase function. Looking for another erase function.
