Hi flaty_star,

It seems you are using custom carrier board for AGX Orin with R35.4.1.

Please refer to the following thread for UART interface on AGX Orin.
Unable to correspond to "func" and "uart_tx" - #3 by KevinFFF

Have you configured the pinmux spreadsheet to enable every UART interfaces?

Please share the full dmesg for further check.
