Are you using the following settings? They work for an iMX7, which may not be the same settings as an iMX6, but it seems likely they are.

Speed (baud): 115200

Data bits: 8

Stop bits: 1

Parity: None

hi @alimert

Welcome to the Toradex Community!!!

Could you provide the version of the hardware and software of your module?
Which carrier Board are you using?

Concerning your issue, could you please check the Uart connection, if it is properly done?

When you open a serial connection, then the Uart settings on module and host must be the same. This is settings, you need to have on your host:

Speed (baud): 115200
Data bits: 8
Stop bits: 1
Parity: None

For the Debug Console, the speed can be set in U-Boot. Default is 115200. If you don’t know which speed is set there, then either you can reinstall a regular Bsp Image using Toradex Easy Installer or you can ssh to the module and change the speed by launching the following command:

fw_setenv baudrate 115200
