Jetson Orin Nano Devkit cannot communicate with RTK GPS

Reopening this issue I am interfacing using USB.

Hi,

As per the previous suggestion I have updated Jetpack to 5.1.2 (r35.4.1). I am still not able to communicate RTK gps using USB.

I still get the following error when running with ros2 node.

[INFO] [launch]: All log files can be found below /home/robogoat/.ros/log/2024-04-06-22-09-18-130908-robogoat-desktop-10790

[ublox_gps_node-1]   what():  U-Blox: Could not open serial port :/dev/ttyACM0 open: Permission denied

On running minicom - D /dev/ttyACM0, I am not able to see any data incoming.

Following is Jetpack version,

Hi,
Do you re-flash the system through SDKManager? There are partitions in QSPI and if you don’t do clean re-flash, the partitions may not be refreshed.

And please use latest Jetpack 5.1.3.
