  OpenOCD Tutorial

  install deps

  sudo apt-get install build-essential

  sudo apt-get install autotools-dev autoconf automake libtool

  sudo apt-get install texinfo libudev-dev libusb-1.0-0-dev libfox-1.6-dev

  Download FTDI driver

  http://www.intra2net.com/en/developer/libftdi/download.php
  tar xf libftdi1-1.2.tar.bz2
  

  HIDAPI

  git clone git://github.com/signal11/hidapi.git
  ./bootstrap
  ./configure
  make
  sudo make install
  

  Build and Install OpenOCD

  git clone git://git.code.sf.net/p/openocd/code
  cd code
  ./bootstrap
  cd ../
  mkdir ./openocd-build
  cd openocd-build
  ../code/configure --with-ftd2xx-linux-tardir=../libftdi1-1.2 --prefix=/opt/openocd --enable-jlink --enable-ftdi --enable-stlink --enable-ti-icdi --enable-ulink --enable-usb-blaster-2 --enable-cmsis-dap --enable-bcm2835gpio
  make
  make install
  

  Usage

  Prepare extra OpenOCD cfg commands

  create file openocd.cfg with following contents:

  $_TARGETNAME configure -event gdb-attach {
     echo "Halting target"
     halt
  }
  

  Start OpenOCD server to Debug LPC11U35

  sudo openocd -f interface/cmsis-dap.cfg -c "transport select swd" -f target/lpc11xx.cfg -f openocd.cfg 
  
  

  Flash and Debug

  • First, flash debug firmware on board

  telnet localhost 4444
  reset halt
  flash probe 0
  flash write_image erase /home/yliu/projects/ib51822/IBDAP-FW/Firmware/IBDAP/Debug/IBDAP.bin 0x0
  reset
  exit
  

  • Second, debug using the commands:

  target remote localhost:3333
  break IBDAP.c:103
  monitor reset halt
  monitor reset init
  continue

  Breakpoint limits

  set remote hardware-breakpoint-limit 4
  set remote hardware-watchpoint-limit 2

  OpenOCD nRF51822 using IBDAP

  Launch OpenOCD

  $ sudo openocd -f interface/cmsis-dap.cfg -c "transport select swd" -f target/nrf51.cfg
