There has been a regression with USB-C in the latest rolling release for Armbian M2 with kernel 6.19.0 RC6. (26.2.0-trunk.332) I tested multiple USB devices in the USB-C port. None of them worked. All worked previously in kernel 6.18.0 RC6. I'm going to downgrade and confirm back here.

@Andrés Pérez Domínguez x your board has the UART pins clearly marked on the board. https://linux-sunxi.org/UART Install this to get more debug u-boot/kernel information on your board. I use a CP2102.

What does that mean? Panfrost is the GPU driver, for the Mali-T820 GPU. I have hardware acceleration for 3D graphics and video playback, in Armbian.

There is no gpu support in these amlogic tvbox builds.
