M95D 0 Posted September 28, 2023 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. Share this post Link to post Share on other sites

M95D 0 Posted October 18, 2023 "Very rarely detected" means the error happens frequently and it only works sometimes. The error is this one: [ 4.670203][ T34] mmc_host mmc2: card is non-removable.

tooz 52 Posted October 19, 2023 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) [ 4.394371] mmc_host mmc2: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0) [ 4.489425] mmc_host mmc2: Bus speed (slot 0) = 49500000Hz (slot req 50000000Hz, actual 49500000HZ div = 0) [ 4.490020] mmc2: new high speed SDIO card at address 0001 [ 6.561012] mmc2:mmc host rescan start!
