Building and Signing

Building the project STM32CubeIDE is required.

In general you have to loosely follow these steps to build and sign images for the bootloaders.

1. Import the projects into a workspace.
2. Generate a key for image signing. For development this can be achieved by running generate_dev_key.sh from the tools folder of the display bootloader.
3. Build the bootloaders.
4. Flash the bootloaders. e.g. using STM32CubeProgrammer, or using the RUN command
5. Build the user application firmwares.
6. (Option 1) Directly flash the firmwares onto devices (use the the output elf file). e.g. using STM32CubeProgrammer, or using the RUN command
7. (Option 2) Sign the images by running sign_all_images.sh from the tools folder of the display bootloader.
8. (Option 2) Copy the signed (without _unsigned) .BIN files onto an SD card. And flash using the bootloader.

Flashing

Display

Flash the display with the STM32CubeProgrammer, as external Loader use the MT25QL128A_STM32469I-DK. Flash the Bootloader and then the Display.hex File
