For the purpose of making changes or studying of the code, you may want to compile the code yourself.
First, clone the repository:
git clone https://github.com/DazzlingOkami/debugprobe
cd debugprobe
Initialize and update the submodules:
git submodule update --init --depth=1
Then create and switch to the build directory:
mkdir build
cd build
If your environment doesn't contain PICO_SDK_PATH, then either add it to your environment variables with export PICO_SDK_PATH=/path/to/sdk or add PICO_SDK_PATH=/path/to/sdk to the arguments to CMake below.
Run cmake and build the code:
cmake ..
make
Done! You should now have a debugprobe.uf2 that you can upload to your Debug Probe via the UF2 bootloader.
It support for BMP debug mode compared to the official firmware. It includes support for most targets, but only implements the SWD interface.
Refactored the code of the cdc_uart part and implemented a v2 version. It does not rely on the tud_cdc_connect() interface, which can make it more friendly to the host computer. I'm not sure if using DMA transfer would result in more efficient performance, but I did try it out. It achieves zero copy of data at the application layer.
Use floating point division mode for PIO to achieve more accurate SWD clock frequency.
Optimize the dual core of MCU by using SMP with FreeRTOS.
- BMP JTAG adapter support.
- BMP run and error LED compatible with Debugprobe.
- RTT support based on module within BMP.
