Tools and Software used in HRI project

Adapter

JTAG adapter build by schematics originated by JTAG-ARM9 project and had to be pin-compatible Wiggler device from Macraigor Systems LLS.

Note: for some inexplainable reason, DLink DI604 router don't work properly when JTAG implements nTRST connection. If you face such problem - simply disconnect this pin.

Check FAQ for alternatives.

JTAG software

Original Wiggler software

Using benefits of compatibility with a Wiggler, I used following free software from Macraigor Systems:

• OCD Commander for Windows - an excellent low-level debugger, perfect for bringing up hardware and test initialisation code and so on... Easy to learn and to use.
• GNU-based Toolkit for CYGWIN, includes binutils 2.10, gcc 2.95.2,Insight 5.0,Arm7/Arm9/NetSilicon LibRemote.
  Toolkit Installation contains three steps:
  1. CYGWIN Installation
  2. GNU ARM7 Toolkit installation
  3. LibRemote library installation

  During GNU tools installation, files are placed in the following directories:

  /usr/local/bin - binary GNU tools + LibRemote + OCDemon binaries

  /usr/local/arm-elf/OCDemon-arm7-example - example source & Makefile

  /usr/local/arm-elf/bin -

  /usr/local/lib/gcc-lib/arm-elf/ -

  windows/system - OCDemon support binaries

  The arm-elf tools are added to /usr/local/bin each has "ARM-ELF-" added to the tool CAPITALISED name (ie ARM-ELF-GDB and ARM-ELF-GCC) to differentiate it from the x86 versions of the same commands.

  Several example gdb.ini files are provided.
  1. arm-elf-gdb (brings up the Insight windowed version of GDB) or
  2. arm-elf-gdb -nw (brings up the traditional command line GDB)

  See /usr/local/bin/readme.txt for more information on GDB JTAG-specific configuration and commands.

Open Source JTAG software

To read flash memory content, I used a very popular armtool from open source arm-boot project. Unfortunately, original pointer (http://kabel.home.at:5880/cgi-bin/viewcvs.cgi/arm-boot/) is not working any more.

A newest sources may be obtained from http://home.at/cgi-bin/viewcvs.cgi/midori/sources/armtool/ and we have fresh compile/usage instructions available.

To accommodate Wiggler compatible adapter, following definitions had to be made in jtag_io.c file (old version from arm-boot project, it is not needed to newer armtool):

#define MASK_TMS_BIT   0x02 //2 //0x04
#define MASK_TCK_BIT   0x04 //1 //0x02
#define MASK_TDI_BIT   0x08 //4 //0x01
#define MASK_RST_BIT   0x01 //8
#define MASK_TDO_BIT   0x80     //0x10

/* Polarity of signals */
#define INVERT_TMS 0            // 0
#define INVERT_TCK 0            // 0
#define INVERT_TDI 0            // 0
#define INVERT_RST 0
#define INVERT_TDO 1            // 1

In general, following definitions could be used to use Wiggler adapter with other open source JTAG software.

/*
 * data D[7:0] (pins 9:2)
 */
#define TDI     3
#define TCK     2
#define TMS     1
#define TRST    0

/*
 * 7 - BUSY (pin 11)
 * 6 - ACK (pin 10)
 * 5 - PE (pin 12)
 * 4 - SEL (pin 13)
 * 3 - ERROR (pin 15)
 */
#define TDO     7 //(inverted)

You'll need a level shifter like this one in case your board have a serial (3.3V) UART

Please note that this make a RS232C COM PORT, so you'll need a cross-over cable to connect it to a serial port i.e. on a PC (another approach would be crossover pins 2 & 3 and use a female DB9 connector)

Dissassembler is a must to have tool when you reverse engineering original firware or flash memeory image.

• DISARM open source - a good open source disassembler for ARM7 is done by Gareth McCaughan. It is easy to use it , understand and modify if needed
• OBJDUMP - After using DISARM for a while, I realise that a OBJDUMP from BINUTILS could be used as a good disassembly tool when called like this:
  objdump -b binary -m arm7tdmi -D file_name Note: binutils had to be compiled with support for ARM archetecture.

ARM Toochain for CYGWIN

Precompiled GNU toolkit for ARM for CYGWIN environment could be downloaded from OpenWinCE project (see http://sourceforge.net/projects/openwince/ ).

Package arm-elf-3.0.4-2.cygwin.tar.bz2 include GCC with following parameters:

Openwince JTAG instructions (Linux)

ARM Toochain for LINUX

You can compile your own ARM cross-compile enviroment using the instructions here: Snapgear arm-elf-gcc build . You may download a precompiled binaries from Snapgear web site.

Soft Osciloscope

Oscilloscope for Windows is a Windows application that converts your PC into a powerful dual-trace oscilloscope. Oscilloscope uses your PC's sound card as an Analog-to-Digital Converter (ADC) to digitize any input waveform (speech, music, electric signal, etc.) and then presents it on the monitor in real time, allowing the user to control the display in the same way as on a conventional "standalone" scope, for example change gain, timebase or plot Lissajous patterns.
