Oct 2022: initial nsh configuration. LCD seems working.

Programming
|
|
===========
|
|
|
|
The device can be normally flashing and debugging over SWD interface or flashing via
|
|
USB interface when the device is in DFU mode using STMicro's STM32CubeProgrammer. The
|
|
DFU mode will be activated after pressing two round button for 30s. Original firmware
|
|
can be flashed back and stay working until the secure flash area is not changed.
