stm32-blink

This is a simple blink example written in assembly for the Blue Pill board (STM32F103C8T6).

Build

You'll need the arm-none-eabi toolchain installed. On Ubuntu:

sudo apt install binutils-arm-none-eabi gcc-arm-none-eabi gdb-arm-none-eabi

To build the blink example:

git clone https://github.com/moefh/stm32-blink.git
cd stm32-blink
make

This will create the file blink.bin in the src directory.

Run

You'll need a Blue Pill board and a ST-Link programmer.

The open source tool to upload programs to the board is st-flash. You can either grab a release from https://github.com/stlink-org/stlink/releases/latest or compile it yourself (there's a Ubuntu package stlink-tools which provides st-flash, but the latest version is too old and doesn't seem to support the STM32F103C8T6).

If you choose to compile it yourself, the steps for Ubuntu are:

sudo apt install cmake libusb-1.0-0-dev
git clone https://github.com/stlink-org/stlink
cd stlink
make
sudo cp build/Release/bin/st-* /usr/local/bin

After you have st-flash installed, upload the blink program to the board with:

sudo st-flash --reset write src/blink.bin 0x8000000
