- Add a basic Modbus RTU server implementation based on Zephyr samples.
- Configure usart1 for Modbus via a board overlay.
- The server initializes and runs, but polling with mbpoll results in a timeout.
- This commit captures a functional but non-working state for further debugging.
- Enable the console subsystem and printk for debugging output.
- Configure the console to use the UART peripheral (usart1 on PA9/PA10).
- Disable RTT to ensure UART is the active console.
- Remove redundant DTS_ROOT from CMakeLists.txt as it's inferred from BOARD_ROOT.
- Clear the project configuration (prj.conf) to start with a minimal baseline.
Remove the top-level and configure each application to directly include the directory as a module or root. This simplifies the build process by making each application more self-contained while still allowing access to shared boards and libraries.
This commit captures a working multi-app build where the board definition is located in the 'software' directory and explicitly included by the slave_node application. This serves as a stable baseline.
- Reorganize the software directory to support multiple Zephyr applications (gateway, slave_node).
- Create a clear separation between applications and shared libraries.
- Add placeholder files for gateway and slave_node applications.
