Sergetsp Posted September 20, 2023 Share Posted September 20, 2023 Hello! I have installed Armbian Bookworm on Khadas VIM3. Also I have enabled "UARTa" , "UARTc" in armbian-config utility. After reboot in file /boot/armbienEnv.txt I have checked options about uart (uarc). Also there are many files /dev/ttyS[0-7] exists. After this I try to connect "minicom -D /dev/ttyS0" (ttyS0, S1, and S3 etc). But no answer from my device on pins 15,16 OR 18,19 (this is a UARTA,UARTC, UART linux). Python sripts pyserial output: "i/o error". Does Armbian (Bookworm or Jammy) supports Khadas VIM3 UART? Are there successful cases? One more question: On Ubuntu Server files /dev/ttyS* are absent. However Khadas supports UART (on https://docs.khadas.com/products/sbc/common/applications/gpio/uart ) Thank you! 1 Quote Link to comment Share on other sites More sharing options...
yannbouteiller Posted November 6, 2023 Share Posted November 6, 2023 (edited) Hello, I am trying to use the UART-C pins (15 for RX, 16 for TX, 17 for GND), and I am facing the same issue 😕 Does someone know how to properly enable UART on those pins in Armbian on the VIM3 (pro) please?
