When I try to connect my flight controller via UART in nsh terminal I got the error like: micrortps\_client: command not found I wote the terminal before it make\_holybro\_durandal-v1\_rtps then it works, I thought I need to upload it then I tried but it gave me the message like: ~/PX4-Autopilot$ make holybro\_durandal-v1\_rtps upload [0/16] Performing build step for ‘px4io\_firmware’ ninja: no work to do. [1/5] Performing build step for ‘bootloader\_firmware’ ninja: no work to do. [4/5] uploading px4 Loaded firmware for board id: 139,0 size: 1809153 bytes (92.02%), waiting for the bootloader… Attempting reboot on /dev/serial/by-id/usb-Holybro\_PX4\_DurandalV1\_0-if00 with baudrate=57600… If the board does not respond, unplug and re-plug the USB connector. And nothing happened, just continue giving me the message and I replug my controller same issue happened.What can I do? ---

Hi @tugbakara, I also faced similar issues with the px\_uploader python script. Instead of unplug and plug let it timeout and try again the same command. That usually works for me. **./px\_uploader.py …/build/holybro\_durandal-v1\_rtps/holybro\_durandal-v1\_rtps.px4 --port /dev/ttyACM0** ---

I tried it also but it is uploading the firmware not the rtps so I am still searching the solution… When I am in the nsh terminal then I write the micrortps\_client nsh give me this message: micrortps\_client COMMAND NOT FOUND. ---

Im sorry but I dont follow you. Do you mean you cant compile with rtps? Upload? ---
