This is a vanilla Eclipse CDT project. Import it into your workspace and (assuming you have ARM cross compiler installed) it should be straightforward.

The application is mainly interrupt driven, with an event queue being dispatched by main().

Key updates

It turned out that FreeRTOS added no value, so it was removed
DFU can be achieved by jumping directly into the ROM bootloader, so there is no need for hardware to manipulate the BOOT0 pin
The TX_DISABLE signal is now supported. It is active low in board 9.x and active high in board 10.x and higher
Board 9.3 adds 3 "status" (LED driving) signals for GPS, RX and TX
Board 10.x needed a GPIO swap to make routing viable and inverted the logic of the TX_DISABLE signal, but it's all abstracted in the BSP
The new 'cli' command was introduced to reboot the board into 'quiet' mode, making it a lot easier to program and verify the station data
Station metadata is now stored in MCU flash, so it is handled in the Configuration class instead of the BSP. The EEPROM is obsolete.

Building and flashing

You will need Eclipse CDT with the MCU package, plus the ARM GCC crosscompiler toolkit. You may need to tweak toolkit paths for the build to work.

The project supports the following STM32 MCUs: L412, L422, L431 and L432.

The openocd-flash-*** scripts in this folder can be run against an STLink programmer to flash the corresponding binary directly to the MCU without any kind of Debug session in Eclipse.
