Issue report - Error accessing ICH RCRB, 0x4000 bytes at 0x00000000fed1c000
Hello, While I was trying to internally flash the bios chip I step in this issue. I am nowhere near a programmer or computer literate, but I followed step by step the documentation. Are you familiar with this issue? Many thanks for your work!! paolo@localhost:~> sudo '/usr/local/sbin/flashprog' -p internal -V [sudo] password di root: flashprog unknown on Linux 6.10.3-1-default (x86_64) flashprog is free software, get the source code at https://flashprog.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). flashprog was built with GCC 13.3.1 20240807 [revision 9d368828bd4d04ce507e02a581be850fca849fae], little endian Command line (3 args): /usr/local/sbin/flashprog -p internal -V Initializing internal programmer Found candidate at: 00000500-00000528 Found coreboot table at 0x00000500.

this is likely because of a conflicting kernel driver. You can try $ sudo modprobe -r lpc_ich There are also a few more hints in the FAQ: https://flashprog.org/wiki/FAQ Don't forget to make a backup first! :) Nico
