Hello Dmitry,
welcome to the coreboot mailing list.
Could you please help me to solve some problems? Laptop: Roda RK9 Socket: mPGA479M
The problem is that when loading coreboot, "Unsupported FSB clock" is written in the debug and the circuit board is turn off. We knew that the function MCHBAR32(CLKCFG_MCHBAR) returns 0xffffffff which is cirtanly not correct. Can this problem be connected with the fact that in this coreboot version Socket BGA956 is used for Roda RK9 and Socket mPGA479M is on the circuit board.
Within coreboot, the socket option is just used to indirectly select the supported CPUs. When we worked on the RK9 support, we were just lazy and selected SOCKET_BGA956 to actually select MODEL_1067X. This should (hopefully) work with any processor listed in [1]. Just to be sure, which processor is socketed in your RK9?
However, the selection of a wrong socket or cpu model shouldn't cause the problem you're describing. Maybe I can identify something that differs from the RK9 we used during development. Please paste the output of the following commands after booting to Linux with the legacy BIOS:
dmidecode lspci -nn lspci -xxx -s 0:00.0
Regards, Nico
