Mass storage interface for drag-drop programming +2. Full ST-Link in-circuit debugger +3. UART bridge for logs/consoles + +We will use a few of these interfaces below to program and interact +with out Nucleo dev board. + +## Build + +```bash +make BOARD=nucleo-f412zg -j +``` + +## Program + +The easiest way to flash the Nucleo board is to Copy-Paste/Drag-Drop +the firmware image onto the exposed mass storage drive. + +Open a file browser and `Copy` the file in `build/nucleo-f412zg/ec.bin`. +Now, find the removable storage that the Nucleo device has presented, +and `Paste` the file into the directory. + +## Interact + +After the Nucelo finishes programming, you can open the EC console. +On GNU/Linux, this is mapped to `/dev/ttyACM0`. + +Install `minicom` and issue the following command: + +```bash +minicom -D/dev/ttyACM0 +``` + +# Unit Testing + +A fun EC feature is that unit tests can be run on-device. + +This is made possible by an alternative build rule that generates a +test image per unit test. These test images use a unit test specific taskset +and console command to trigger them. + +## Create + +To enable an existing unit test, add it to the [build.mk](build.mk)'s +`test-list-y` variable. + +See the main [README.md](/README.md) on how to write a new unit test. + +## Build + +To build all unit test images for this board, run the following command: + +```bash +make BOARD=nucleo-f412zg tests +``` + +You can build a specific unit test image by changing `tests` to `test-aes`, +for the `aes` unit test. + +## Flash + +Copy/paste the `build/nucleo-f412zg/${TEST}/${TEST}.bin` file to the +Nucleo's mass storage drive, where `${TEST}` is the name of the unit test, +like `aes`. + +## Run + +1.
