Hi SWu.2354,

If this topic is about the usage of the MPU serial console for non MPU devices the answer is no this can't work, or at least needs specifics settings.0690X00000BukCiQAJ.png

This console has hard-coded settings for MPU purpose.

Hence either the UART handle init should respect the following settings and you can use above console

UartHandle.Init.BaudRate = 115200;
UartHandle.Init.WordLength = UART_WORDLENGTH_8B;
UartHandle.Init.HwFlowCtl = UART_HWCONTROL_NONE;

or you may have to define your own board connection from the Connection view:

Window > Show View > Other

And then right click on your defined connection > open command shell.

Hope this helps.
