M.2 Wifi card slot doesn't work on BUDDY

[Zema4You]

Generally Buddy works fine with MsChromebox firmware, thank You😊 I’m trying to install Realtek 1GbE card (RTL8111) in Buddy Wifi M.2 slot but card is not active in OS and is not listed in UEFI Shell by PCI command. I have modified my card to give GND to CLKREQ# pin and card started working in other mainboards (thank two namezys in https://github.com/MrChromebox/firmware/issues/512#issuecomment-1703398317 ), but not in Buddy. I have tried also another 2 wifi cards in this slot but none worked. Any suggestions how to start wifi slot working in Buddy?

Have a good day

[MrChromebox]

only thing I can think of is to disable CLKREQ usage on the wifi port and see if that helps - would require a custom firmware build

[Zema4You]

Let’s try this. It can help if CLKREQ is not connected to the M.2 socket at all.

[MrChromebox]

drop me an email or ping me on IRC/Discord and I'l give you a test build to try

I have found one card that works in M.2 Wifi slot in BUDDY - Intel I210. Then the issue is limited only to some cards. I will investigate further and give info when find something new.

I have rechecked 5 cards and all that have connected CLKREQ, also Realtek card after grounding CLKREQ works (again thanks two namezys in https://github.com/MrChromebox/firmware/issues/512#issuecomment-1703398317 ).

So it was human failure when I was checking before and issue is false positive.

Best regards
