I use agx orin 32G modules.
Self-developed base plate.

I found that the serial port could not be used when debugging before.

Orin-TRM_DP10508002_v1.2p.pdf UARTG is not found in the manual。

I would like to know whether the corresponding UARTG of the two pins B48 and B49 can be used in this interface. What does it need to be configured?

Hi 2381783554,

What’s the Jetpack version in use?

You can find the UART mapping for AGX Orin in https://elinux.org/Jetson/L4T/peripheral/#Mapping_3.

From the pinmux spreadsheet, it seems it is not available to be used as it shows FSI UART (not used by the commercial SKU)
