The bootloader scans the program memory for a valid firmware by
testing the checksum, which takes a moment. If everything is correct,
the "firmware found!" message appears.
After the initialization process is done, which may take a moment, the
device's identification number (for example, 41239) and error code (in
this example, 0) are displayed. After another moment, the firmware
mode's command line interface prompt is displayed (#).
If you need to return to bootloader mode when you're in firmware
