Download the toolchain from Arm GNU Toolchain Downloads according to your pc architecture, extract the files
sudo mkdir -p /opt/gcc-arm/
sudo tar xvf arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi.tar.xz -C /opt/gcc-arm/
cd /opt/gcc-arm/
sudo chown -R root:root arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/Download and install JLink from J-Link / J-Trace Downloads.
# installation command for .deb
sudo dpkg -i JLink_Linux_V784f_x86_64.deb
# uncompression command for .tar.gz
sudo tar xvf JLink_Linux_V784f_x86_64.tgz -C [target folder]The default installation directory is /opt/SEGGER
Copy [Project directory]/Misc/Flash/JLinkDevices to [User home]/.config/SEGGER/JLinkDevices/
cd py32f0-template
cp -r Misc/Flash/JLinkDevices/ ~/.config/SEGGER/Read more: https://wiki.segger.com/J-Link_Device_Support_Kit
Don't install from apt repository, because the version 0.13.1+dfsg-1 is too low for J-Link probe.
Install PyOCD from pip
pip uninstall pyocdThis will install PyOCD into:
/home/[user]/.local/bin/pyocd
/home/[user]/.local/bin/pyocd-gdbserver
/home/[user]/.local/lib/python3.10/site-packages/pyocd-0.34.2.dist-info/*
/home/[user]/.local/lib/python3.10/site-packages/pyocd/*
In Ubuntu, .profile will take care of the PATH, run source ~/.profile to make pyocd command available
Clone this repository to local workspace
git clone https://github.com/IOsetting/py32f0-template.gitChange the settings in Makefile
- USE_LL_LIB Puya provides two sets of library, HAL and LL, set
USE_LL_LIB ?= yto use LL instead of HAL. - ENABLE_PRINTF_FLOAT set it to
yto-u _printf_floatto link options. This will increase the binary size. - USE_FREERTOS Set
USE_FREERTOS ?= ywill include FreeRTOS in compilation - USE_DSP Include CMSIS DSP or not
- FLASH_PROGRM
- If you use J-Link,
FLASH_PROGRMcan be jlink or pyocd - If you use DAPLink, set
FLASH_PROGRM ?= pyocd - ST-LINK is not supported yet.
- If you use J-Link,
- ARM_TOOCHAIN Make sure it points to the correct path of arm-none-eabi-gcc

If Cortex Debug cannot find JLinkGDBServerCLExe, add the following line to settings.json
"cortex-debug.JLinkGDBServerPath": "/opt/SEGGER/JLink/JLinkGDBServerCLExe",
