- DFU can be achieved by jumping directly into the ROM bootloader, so there is no need for hardware to manipulate the BOOT0 pin

The project supports the following STM32 MCUs: L412, L422, L431 and L432. The project supports the following STM32 MCUs: L412, L422, L431 and L432.
There are multiple build configurations. Some of these configurations can be installed directly at address 0x08000000, without any bootloader.
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. Configurations with "bootloader" in the name are linked for use with the new MAIANA bootloader only and will not function if installed at the top of flash.
