STM32Fx_FreeRTOS_Base

FreeRTOS starter project for STM32 microcontrollers.

Prerequisites

1. GNU Make
2. gcc-arm-embedded

Creating a new project:

1. Create (if necessary) board and CPU definitions (see existing examples for details).
2. Create an application folder in the apps directory
3. Create a config.mk file for your application (see existing examples)
4. Store your application code in the newly created directory and edit your config.mk file appropriately

Building

1. 'cd' to the root of base project directory
2. type 'make APP=your_app_name'

Debugging

1. Install openocd with support for your JTAG dongle
2. Add an openocd.cfg to your project (see existing examples)
3. Install DDD (data display debugger) (optional)
4. Type: sudo make APP=your_app_name openocd (this starts the debugger)
5. Attach your favorite debugger (gdb/ddd/insight) to the openocd session (a make command for ddd is included in the makefile)

ITM Trace output

1. Download, build, and install swo-tracer
2. Compile and flash your firmware
3. Start openocd with trace support (see example openocd.cfg files)
4. Start gdb and enable semihosting (make APP=your_app gdb)
5. Launch swo-tracer and point it at the swo.log file that is generated by openocd (swo-tracer -t swo.log). You may need to use sudo
6. Use GDB to reset your firmware and any printf output should be displayed in the swo-tracer screen
