Hello, is there a known solution to my problem? After flashing the coreboot and booting the computer, I can use the integrated GPU through VGA, but initialization of amdgpu fails and DisplayPort external GPU isn't recognized by the system. It appears in lspci, though.
I can provide better logs tommorow, but that's part of what appeared in dmesg: amdgpu get bioss error acpi vcft image header truncated amdgpu kernel bo map failed [...] error -22 amdgpu_vram_scratch_init failed [...] error -22 fatal error in GPU initialization
My specs: F2A85-M A10-6800k with integrated Radeon HD 8670D AMD RX 570 a external GPU I've used coreboot with Seabios
If there are some known solutions to the problem, please let me know. Otherwise I could use a list of files and command outputs I should provide to give better information. Thank you for your help.
