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/
Clone this repository to local workspace
git clone https://github.com/IOsetting/py32f0-template.git
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/

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 pyocd
This 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
Change the settings in Makefile
- USE_LL_LIB Puya provides two sets of library, HAL and LL, set
USE_LL_LIB ?= y
to use LL instead of HAL. - ENABLE_PRINTF_FLOAT set it to
y
to-u _printf_float
to link options. This will increase the binary size. - USE_FREERTOS Set
USE_FREERTOS ?= y
will include FreeRTOS in compilation - USE_DSP Include CMSIS DSP or not
- FLASH_PROGRM
- If you use J-Link,
FLASH_PROGRM
can 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

Install Cortex Debug extension, add a new configuration in launch.json, e.g.
{
"armToolchainPath": "/opt/gcc-arm/arm-gnu-toolchain-12.2.rel1-x86_64-arm-none-eabi/bin/",
"toolchainPrefix": "arm-none-eabi",
"name": "Cortex Debug",
"cwd": "${workspaceFolder}",
"executable": "${workspaceFolder}/Build/app.elf",
"request": "launch", // can be launch or attach
"type": "cortex-debug",
"runToEntryPoint": "Reset_Handler", // "main" or other function name. runToMain is deprecated
"servertype": "jlink", // jlink, openocd, pyocd, pe and stutil
"device": "PY32F030X8",
"interface": "swd",
"preLaunchTask": "build", // Set this to run a task from tasks.json before starting a debug session
// "preLaunchCommands": ["Build all"], // Uncomment this if not using preLaunchTask
"svdFile": "${workspaceFolder}/Misc/SVD/py32f030xx.svd", // svd for this part number
"showDevDebugOutput": "vscode", // parsed, raw, vscode:vscode log and raw
"swoConfig":
{
"enabled": true,
"cpuFrequency": 8000000, // Target CPU frequency in Hz
"swoFrequency": 4000000,
"source": "probe", // either be “probe” to get directly from the debug probe,
// or a serial port device to use a serial port external to the debug probe.
"decoders":
[
{
"label": "ITM port 0 output",
"type": "console",
"port": 0,
"showOnStartup": true,
"encoding": "ascii"
}
]
}
}
If Cortex Debug cannot find JLinkGDBServerCLExe, add the following line to settings.json
"cortex-debug.JLinkGDBServerPath": "/opt/SEGGER/JLink/JLinkGDBServerCLExe",
More examples can be found in Examples folder, copy and replace the files under User folder to try different examples.
