Run the command by entering it in the MATLAB Command • If a serial console on the Linux host is desired, a serial cable must be plugged into the serial port on the target and connected to your Linux host directly or through a serial-to-USB converter. The card has been verified working on other machines running several kernel versions, and another card has been tried in th The reason for this is that all of the devices sharing the same hardware connection in the GMSL setup must be identified to the I2C bus with unique physical I2C slave addresses. Initially I tested the telemetry port of pixhawk by connecting it to my pc using a USB to tty cable and mavros. After struggling for a while, I solved the problem and decided to write this guide Known Devices that might have this problem: – Some Arduinos – RS232 to USB serial converter If you happen to have such device, by typing in command lsusb You might see In this application, we use our DSBOARD-NX2 with NVIDIA Jetson Nano module, so the name of the port is “/dev/ttyTHS1”. The other UARTs are available for general use. Thanks once again. common : -CMDLINE_ADD="console=ttyS0,115200n8 console=tty0 OS=l4t fbcon=map:0 net.
