arm-development's Introduction

Installing OpenOCD (On-Chip Debugger)

# Mac OS X
brew install openocd

# Ubuntu
sudo aptitude install checkinstall
tar -zxvf openocd-x.y.z.tar.gz
cd openocd-x.y.z.tar.gz
./bootstrap
./configure --prefix=/usr --enable-stlink --enable-jlink --enable-amtjtagaccel --enable-ft2232_libftdi
make
sudo checkinstall make install

Installing cross-compiler

# Ubuntu
sudo aptitude install gcc-arm-none-eabi

# Mac OS X
brew install mpfr gmp libmpc libelf texinfo
git clone https://github.com/jsnyder/arm-eabi-toolchain
cd arm-eabi-toolchain
make install-cross

echo "export PATH=~/arm-cs-tools/bin:$PATH" >>~/.zshrc

Installing ChibiOS

git clone https://github.com/ChibiOS/ChibiOS-RT
cd ChibiOS-RT/demos
cp -r ARMCM3-STM32L152-DISCOVERY ~/arm-devel
cd ~/arm-devel
rm -rf iar keil

Change Makefile to point CHIBIOS to the correct path. Alter main.c as desired. Then make.

Using OpenOCD to upload binary

cd ~/arm-devel
openocd -f /usr/share/openocd/scripts/board/stm32ldiscovery.cfg

From another terminal, upload the binary to the board.

telnet localhost 4444

# show current status
poll

# halt processor
reset halt

# show flash details
flash probe 0

# write binary to flash
flash write_image erase build/ch.bin 0x08000000

# reset unit and exit
reset
exit

There's some neat stuff in one of the links below about using gdb to debug the process running on the chip. Something to keep in mind for the future.

Using st-flash instead of OpenOCD

Build st-flash

# Ubuntu
sudo aptitude install build-essential autoconf

# Mac OS X
brew install libusb

git clone https://github.com/texane/stlink
cd stlink
./autogen.sh
./configure
make
cd flash
make

sudo cp ./st-flash ~/bin

Uploading using st-flash
