Each weact-stm32h743 configuration is maintained in a sub-directory and can be selected as follow:

./tools/configure.sh weact-stm32h743:<subdir>

Where <subdir> is one of the following:

Configuration Directories

nsh

Configures the NuttShell (nsh) located at apps/examples/nsh. This configuration enables a serial console on UART1.

usbnsh

Configures the NuttShell (nsh) located at apps/examples/nsh. This configuration enables a serial console over USB.

After flashing and reboot your board you should see in your dmesg logs:

[ 2638.948089] usb 1-1.4: new full-speed USB device number 16 using xhci_hcd
