Dear Support,
I have been working on the imx8 mini using a Verdin development board.
I did a test from ubunto20.4, I checked minicom -D /dev/ttyUSBO. all LEDs on the board turn off except the power leds (led25 and led26), and I need to reset them.
Or also screen /dev/ttyUSB0 115200
Could you please explain why? Is it in the debug mode that it happens like that? Or do I need to change some configuration? Thank you so much in advance.

Hi @Mehrdad !

Could you please share the hardware versions (module and carrier board) of your setup?

Also, which OS are you using? And which version?

Best regards,

Hi @Mehrdad !

Please check the documentation in this Configuring Serial Port Debug Console (Linux/U-Boot) article to understand which ttyUSB you should use.

You will see that it should be the fourth ttyUSB that the module enumerates in your computer.

Best regards,
