Note: The boot loader is entirely separate program that loads ALFAT SoC firmware. The
version number of the boot loader may not match the ALFAT firmware version number. The
boot loader can't be updated.
It is recommended to use the provided firmware updater application. But here is an
example how to use a terminal console like TeraTerm to update the firmware instead.
Put ALFAT in the bootloader mode as explained in
Open the relative COM port and set the baud rate to 115200 and set the New-line receive
to LF.
