On 35.5, we modified the status of uartb: serial@3110000 from disable to okey in the tegra234-soc-uart.dtsi file. Then it can generate the/dev/ttyTHS1 node. Our Bluetooth uses this ttyTHS1 serial port, which can work. We are currently porting to 36.3 and have found that there is no tegra234-soc-uart.dtsi file on 36.3. How can we enable uartb: serial@3110000 on 36.3? And what is the corresponding node of tty? thank you!
Hi davidlv,
Are you using the devkit or custom board for Orin NX?
Some nodes in device tree have been removed in JP6 by default, please refer to Issue with enabling UARTB serial@3110000 on Orin NX with L4T 36.3 - #3 by KevinFFF for the similar issue as yours.
