IBDAP - Affordable CMSIS-DAP JTAG/SWD Debug Probe

IBDAP's objective is to become an affordable open source & open hardware CMSIS-DAP JTAG/SWD debug probe implemented using gcc & makefile.

Description

Debug adapters are expensive, some could cost thousands of dollars, some may not be compatible among different vendors. Luckily, ARM standardized the debugging interface which is called CMSIS-DAP and released the firmware implementation on some processors, however, you still need a Keil MDK Professional edition software in order to build the firmware, even the open source one provided by mbed and the price for Keil Professional is intimidating. All these barriers has become the first issue that every inventor is facing, and we need a solution!

IBDAP's objective is to become an affordable open source & open hardware CMSIS-DAP JTAG/SWD debug probe implementation using gcc & makefile. Anyone can modify and embed a debug probe on its own device easily with everything under its control.

What’s the current status?

Both the hardware and CMSIS-DAP source codes using gcc are completed and stepping, breakpoints, flashing etc are tested on both debugging itself and nRF51822 processors.

How to flash IBDAP firmware onto IBDAP board

By pressing RESET and ISP buttons at the same time and then release them, a USB mass storage device will show up with a single file "firmware.bin", delete it and paste in the IBDAP-latest.bin file from below. Press RESET button again. Now Firmware flash complete.

How to use IBDAP to debug target board

Connect IBDAP's TGT_DBG 10-pin header to the target board (note, VTREF pin at TGT_DBG provides 3.3V for the target board, but you can switch off by removing the corresponding jumper), connect IBDAP and PC via USB cable.

If your system is Windows, you should be able to see a USB HID device called "IBDAP-LPC11U35 CMSIS-DAP" in your control panel.

If you are using Keil

From your Keil project, click on "Options for Target" button just besides the target, choose "Debug" tab, select use: "CMSIS-DAP Debugger", then click "settings", you should be able to see the "IBDAP-LPC11U35 CMSIS-DAP" device with any error, if yes, then we are all set.

Step 1

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

http://wiki.paparazziuav.org/wiki/DevGuide/GDB_OpenOCD_Debug

Breakpoint limits

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