    • RE: How to Enable QUP19 and QUP13 as UARTs on VOXL 2 (ttyHS2 / ttyHS3)?

      @Alex-Kushleyev

      
      Hi @yardy
      Are you using the jumper blocks J14.15/J14.17 to JP1.10/JP1.12 respectively for QUP_19?
      

      It was connected to JP1.9/JP1.11 (because of the jumpers... I was wrong)

      It's working!

      Many thanks🤙

      @Alex-Kushleyev , Thanks for the response!

      VOXL 2 mounted on the VOXL 2 Developer Test Board.
      CP2102 USB-to-UART dongle connected to my PC.
      For QUP19 (ttyHS2):

      GPIO_2 (TX) connected to RX on CP2102 via JP1 (for level shifter) and J9
      GPIO_3 (RX) connected to TX on CP2102 via JP1 (for level shifter) and J9
      GND to GND

      on the voxl2:

      stty -F /dev/ttyHS2 115200
      cat /dev/ttyHS2
      
      echo "Hello from VOXL2 HS2" > /dev/ttyHS2
      

      on my PC:
      OS: Ubuntu 22.04

      screen /dev/ttyUSB0 115200
      

      When I send text from the PC side, I expect it to appear in the cat output on VOXL2, and vice versa.

      with /dev/ttyHS1 it works.

      @Alex-Kushleyev

      thanks for replying.
      I'm using the dev test board but couldn't establish the comm

      any ideas?

    • How to Enable QUP19 and QUP13 as UARTs on VOXL 2 (ttyHS2 / ttyHS3)?

      Hi everyone

      I'm working on a VOXL 2, M0054 , voxl2_SDK_1.4.1

      I’ve successfully used /dev/ttyHS1 (QUP7) via J3, but I’m currently trying to enable and use:

      /dev/ttyHS2 → QUP19 (GPIO 2 and 3, J5 pins 48 and 49)
      
      /dev/ttyHS3 → QUP13 (GPIO 38 and 39, J5 pins 97 and 98)
      

      These devices show up in /dev, but the corresponding pins remain unclaimed in the pinctrl debug output:

      cat /sys/kernel/debug/pinctrl/*/pinmux-pins | grep -E 'GPIO_2|GPIO_3|GPIO_38|GPIO_39'
      
      pin 2 (GPIO_2): 894000.qcom,qup_uart (GPIO UNCLAIMED) function qup19 group gpio2  
      pin 3 (GPIO_3): 894000.qcom,qup_uart (GPIO UNCLAIMED) function qup19 group gpio3  
      pin 38 (GPIO_38): a94000.qcom,qup_uart (GPIO UNCLAIMED) function qup13 group gpio38  
      pin 39 (GPIO_39): a94000.qcom,qup_uart (GPIO UNCLAIMED) function qup13 group gpio39 
      

      How can I claim it to UART?

      Many Thanks!
