I connected the 40-pin UART1(THS0) to the Debug UART(TCU0). I send the data “aaaa…” with TCU0. THS0 can receive normally, as shown in [10:48:57:079] on the left. Send data “bbbb…” with THS0. TCU0 cannot receive properly, as shown in [10:49:18:635] on the right, and TCU0 sends some strings, which are captured by THS0.
Why does Debug UART receive an error character?
Hi Jackson_Xue,
Are you using the devkit or custom board for Orin NX?
What’s your Jetpack version in use?
Is the issue specific to CuteCom?
Have you tried to use stty to configure the UART interface and use cat and echo command to verify?
We don’t suggest for this setup since the messages in combined uart (ttyTCU0) are coming from several firmware.
