Kernel v6

Recommended Posts

Did anyone try to use a recent kernel version on Asus Tinkerboard S?

I tried v6.5, but wifi is very rarely detected during boot.

"Very rarely detected" means the error happens frequently and it only works sometimes. The error is this one:

I compiled Gentoo, but I didn't use Gentoo kernel. I used the mainline, official, torvalds' kernel from github.

hello @M95D

kernel v.6 is not supported just yet, the reason why the wifi is hardly detected might be the mmc sdio driver difference (kernel v.6 & kernel v.4.4)
