STM8 development with Eclipse and macOS – nubix-Weblog

Setup Eclipse

Eclipse can be configured to allow development of C++ firmware cod for the STM8 with editing, flashing and debugging. There are some steps that are critical to get Eclipse to work with the STM8 board.

1. Install HomeBrew on Mac

  • HomeBrew is used to comfortably install necessary tools over the command line
  • only needed to be installed if not installed yet
  • maybe ‘brew doctor’ shows errors that have to be fixed before using HomeBrew


ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update
brew doctor

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update
brew doctor

  • ST-LINK/V2 is a programmer and debugger for STM8 and STM32
  • can be installed with HomeBrewn


brew install autoconf automake pkg-config libusb libusb-compat stlink
st-util -h

  • brew install autoconf automake pkg-config libusb libusb-compat stlink
  • st-util -h

brew install autoconf automake pkg-config libusb libusb-compat stlink
st-util -h

Stop!

st-util does not recognize the DISCOVERY board and has problems using it. A quick research shows that the tool only supports the SWD-mode for STM32-MCU’s. The STM8-MCU’s need the SWIM-mode. This mode is only usable with the tool stm8-flash that is not well-maintained. This tool does not allow debugging at the moment. Conclusion: Debugging of STM8 code is not usable under Linux or Mac OS X.

3. Install SDCC Cross-Compiler

brew install sdcc
sdcc -v

  • brew install sdcc
  • sdcc -v

brew install sdcc
sdcc -v

4. Install STM8Flash

git clone https://github.com/vdudouyt/stm8flash.git
cd stm8flash
make
make install
cd ..
rm -R stm8flash
stm8flash

5. Test if the STM8L-DISCOVERY board is responding

stm8flash -c stlinkv2 -p stm8l152?6 -r test.ihx

stm8flash -c stlinkv2 -p stm8s003f3 -r blinky.ihx

stm8flash -c -p [-s flash|eeprom|0x8000] [-r|-w|-v]
The supported file types are Intel Hex, Motorola S-Record and Raw Binary. The type is detected by the file extension.

Flash examples:

./stm8flash -c stlinkv2 -p stm8s003f3 -r blinky.ihx
./stm8flash -c stlinkv2 -p stm8s003f3 -w blinky.ihx

EEPROM examples:

./stm8flash -c stlinkv2 -p stm8s003f3 -s eeprom -r ee.bin # 读取文件
./stm8flash -c stlinkv2 -p stm8s003f3 -s eeprom -w ee.bin # 写入文件
./stm8flash -c stlinkv2 -p stm8s003f3 -s eeprom -v ee.bin # 验证文件

修改OPT选项

echo "00 00 ff 02 fd 00 ff 00 ff 00 ff" | xxd -r -p > option_bytes.bin
stm8flash -c stlinkv2 -p stm8s003f3 -s opt -w option_bytes.bin
stm8flash -c stlinkv2 -p stm8s003f3 -s flash -w voliera.ihx
