Hi Oleksii At first I downloaed your patches and put it in armbian's build tool, it report errors with fusb302 patch Then I downloaded your rk3399-nanopc-t4-type-c-modeling.patch only and add two lines extcon-cables = <1 2 5 6 9 10 12 44>; typec-altmodes = <0xff01 1 0x001c0000 1>; based on Helios64 commit on armbian's git (ea5bf1afd56423c069dd3267e9effc2c62d6706c), then I connect type-c monitor to my nanopct4 board and get these dmesg info: root@nanopct4:~# dmesg |grep dp [ 5.720996] systemd[1]: Created slice system-modprobe.slice.
