As far as I know, there are up to 3 UART in the Jetson Nano:
. In the J41 (40 pins) - general purpose
. In the J44 (A02, no idea where it is in the B01) - for console debug
. In the M2 port
The UART in J41 is okay for using to me. It is the /dev/ttyTHS1.
My question is how I could use the UART in J44 and what is its name in /dev/___ ?
I have search around in the forum but they seem too complicated to me (relating to kernel or something…). Could you guys please guide me the way to solve this as simple as possible?
yes, please delete the line “console-port” and rebuild the kernel to generate a new dtb binary.
