Requirements

Building

1. Install GNU Arm Embedded Toolchain

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_V770a_x86_64.deb

The default installation directory is /opt/SEGGER

Copy all .FLM files from [Project directory]/Misc/Flash/Devices/Puya to [JLink directory]/Devices/Puya

cd py32f0-template
sudo cp -r Misc/Flash/Devices/* /opt/SEGGER/JLink/Devices/

Edit JLinkDevices.xml

sudo vi /opt/SEGGER/JLink/JLinkDevices.xml

Add the following lines in <DataBase> section

  <!--                 -->
  <!-- Puya            -->

  </Device>

2. Option #2: Install PyOCD

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

3. Clone This Repository

Clone this repository to local workspace

git clone https://github.com/IOsetting/py32f0-template.git

4. Edit Makefile

Change the settings in Makefile

  • make sure ARM_TOOCHAIN points to the correct path of arm-none-eabi-gcc
  • If you use J-Link, FLASH_PROGRM can be jlink or pyocd
  • If you use DAPLink, set FLASH_PROGRM to pyocd
  • ST-LINK is not supported yet. ST-LINK works in Windows Keil5, but I failed to make it work in Ubuntu
  • Puya provides two sets of library, HAL lib and LL lib, switch with USE_LL_LIB option
  • ENABLE_PRINTF_FLOAT will add -u _printf_float to link options, which will significantly increase the binary size.
##### Project #####

PROJECT			?= app
# The path for generated files

##### Options #####

# Use LL library instead of HAL
USE_LL_LIB ?= n
# Enable printf float %f support, y:yes, n:no
ENABLE_PRINTF_FLOAT	?= n
# Build with CMSIS DSP functions, y:yes, n:no
USE_DSP			?= n
# Programmer, jlink or pyocd
FLASH_PROGRM	?= pyocd

LIB_FLAGS       = PY32F003x8

5. Compiling And Flashing

# clean source code
make clean
# build
make
# or make with verbose output
V=1 make
# flash
make flash

Debugging In VSCode

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",
