Basic Loader is an update-capable bootloader that supports the unpacking and installing of new firmware on an end-device.
Basic MAC uses this component to load its firmware, and to support firmware updates over-the-air (FUOTA).
The reference hardware platform for Basic Loader is the B-L072Z-LRWAN1 STM32 LoRa™ Discovery kit.
It is recommended to use a recent Ubuntu distribution as build host with the
gcc-arm-embedded package installed.
To build the bootloaders for all supported platforms, simply run make in
the toplevel directory.
Alternatively, change into a specific target board's build directory and run
make there:
cd build/boards/B-L072Z-LRWAN1
make
The output of the build process is a file named bootloader.hex that can be
loaded onto the B-L072Z-LRWAN1 development board. If there is no valid firmware
installed, the LED LD2 will be flashing the corresponding error sequence
(SYNC-2-2-1).
