I have Octoprint installed and I’m trying to use UART1 Rx/Tx pins to connect to my 3d printer board. I cannot get Octoprint to detect the /dev/ttyXXX device. On the Libre aml-s905x-cc its easy to do with ldto enable uarta. How can I enable a UART1 overlay for the ROC-RK3328-CC?
I’m using the raspbian build from the Libre distro.
