Is TRB245 equipped with a debug serial UART port? Where can I find it? I want to access the uboot console. Is that possible?

Hello,

Yes, TRB245 support UART debugging. I am also providing the pinout in the table below:

RX

TX

-

HW_RST

-

GND

-

-

-

3V3

1V8

3V8

The pins are on the PCB on the side of ethernet port.

There is no support for uboot console.

You can upgrade firmware using bootloader if that is why you need to reach the uboot console.

Hello,

I have connected the board , but nothing displaying at the terminal? Do you know how to troubleshoot? What should be the baudrate? I tried with some common baudrates and nothing is transmitting.

I have tested the connection on 115200 baudrate 8n1 no flow control and had no problems. The pinout used was as in my previous comment, 8- TX 8 other side - RX and 6 GND
