AM68A: AM68A EVM: No Serial Debug Log Output (Minicom) following Getting Started Guide

L?i H?i Ðang

Part Number: AM68A

I am attempting to follow the "Getting Started" guide for the AM68A Processor SDK Linux Edge AI (v9.0.0.00) located at: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-edgeai/AM68A/09_00_00/exports/docs/devices/AM68A/linux/getting_started.html.

I have prepared the SD card and configured the serial terminal on my Linux host machine as instructed, but I am not receiving any boot or debug logs on minicom after powering on the board. The terminal remains completely blank. The device have been booted and can ssh to it, but have no serial debug log.

Hi,

There should be 4 COM ports that get enumerated when connecting to the micro USB port. The 3rd port that is enumerated should be the port that has the Linux logs. So to experiment, could you do the following in case the enumeration order is different on your Linux host machine.

Try connecting to all 4 UART COM ports with baud rate of 115200

Regards,

Takuma

i set wrong baud rate (1152000) . Normally i use wrong baud rate, it will have trash character on minicom so i don't care about baud rate issue.
Thank you for your support.
