In dmesg I see that ttyAML0 is a serial port. Is ttyAML0 the gpio uart headers? ttyAML0 is on header 2J1 and it's by default the debug UART You can enable additional UARTs by download this: https://raw.githubusercontent.com/libre-computer-project/libretech-overlays/for-4.13.y/overlays/meson-gxl-s905x-libretech-cc-uarta.dts and using armbian-add-overlays. UART A is on pin 8 and 10.

michaels Posted August 19, 2022 Share Posted August 19, 2022 Hi I also want to use the UART on the 40 pin header pins 8 and 10 of the AML-S905X-CC (Le Potato). I have customized overlays before on the Beaglebone black. While the links above are helpful, where can I download the devicetree overlay package. Is there a tutorial or some documentation on the process. Thanks 0 Quote Link to comment Share on other sites More sharing options...
