Debian Bullseye ships a Mesa version that is too old to contain the required patches for the RK356x SoC's GPU. You can (at your own risk) [https://wiki.debian.org/DebianTesting use the current Debian Testing version ], called "Bookworm". | Debian Bullseye ships a Mesa version that is too old to contain the required patches for the RK356x SoC's GPU.

== How-To == | |||
=== Connect Debug UART === | |||
The easiest way to get debug output is to connect a 3.3V 1.5mbaud capable UART adapter to the board. | |||
To connect it, connect the ground lead to pin 6, and the RX/TX leads to pins 8 and 10 (consider swapping them if you get no output, things are often mislabelled). These pins are "UART2" in the above GPIO table. | |||
Open a serial terminal at 1500000 bauds, e.g. | |||
$ picocom -b 1500000 /dev/ttyUSB0 | |||
