Quick Demonstration of Creating a Simulation Environment for the STM32 Using Renode.

1. Ensure that you have Renode installed for your current platform (https://renode.io/)

2. Clone this repository

3. Open renode in the terminal. In windows, if the executable is added to PATH, you should be able to just type in renode in the powershell.

4. Set up the machine to emulate. In the opened Renode terminal, type in:

   • mach create to instantinate a new simulation machine instance.
   • machine LoadPlatformDescription @platforms/boards/stm32f4_discovery.repl to load the target simulation architecture
   • sysbus LoadELF <path to HelloWorld.elf located in /Binary> to load the target code.

5. In our case, the print statements will appear on Uart2, so we need to observe it by typing showAnalyzer sysbus.uart2 in the machine terminal. Doing this should bring up another terminal.

6. From there, enter start to observe that ZephyrRTOS boots up and "Hello World!" Displays.

The source for the project is located in the repo's /STM32/HelloWorld. It uses platformIO to set up the project scaffolding.
