JTAG Tools
~~~~~~~~~~

JTAG Tools is a software package which enables working with JTAG-aware
(IEEE 1149.1) hardware devices (parts) and boards through JTAG adapter.

This package has open and modular architecture with ability to writing
miscellanous extensions (like board testers, flash memory programmers,
and so on).

JTAG Tools package is free software, covered by the GNU General Public
License, and you are welcome to change it and/or distribute copies of it
under certain conditions. There is absolutely no warranty for JTAG Tools.
Please read COPYING file for more info.

Warning: This software may damage your hardware!

Feedback and contributions are welcome.

Required software
-----------------

Required only for MS Windows:
- Current Cygwin net installation from http://cygwin.com/
- ioperm package from http://openwince.sourceforge.net/ioperm/

Required for all systems:
- include package from http://openwince.sourceforge.net/include/


Build & installation instructions
---------------------------------

1. Download and install required software (see previous section).
2. Download and unpack jtag sources.
3. Setup your parallel cable configuration in src/tap/ctrl.c file.
   Please set correct TCK, TDI, TMS, TRST, TDO and 'port' values in the file.
4. Run ./configure script. Use optional --with-include parameter.
   See `./configure --help` for more info.
5. Run `make`.
6. Run `make install`.


Running JTAG tools
------------------

Connect your JTAG adapter between your PC and target device and turn
on your device.

To run JTAG tools type "jtag" and press <Enter>. jtag should start and
display some initial informations. Output should end with line like this:

jtag>

This is "jtag command prompt". Type "help" and press <Enter> for initial help
about available commands. To exit JTAG Tools type "quit" and press <Enter>.

===> First task: Detect parts on the JTAG chain.

Type "detect" at the jtag command prompt:
jtag> detect

Your output should looks like this:

Device Id: 01011001001001100100000000010011
  Manufacturer: Intel
  Part:         PXA250
  Stepping:     C0
  Filename:     /usr/local/share/jtag/intel/pxa250/pxa250c0

If you get empty output or this error message

	detect_parts: bad JTAG connection (TDO is 1)

your JTAG adapter is not connected properly, or your target board
doesn't work, or your JTAG-aware chip doesn't support JTAG ID detection
(IDCODE instruction).

"detect" command is required before all other commands.

===> Second task: Print current JTAG chain status.

Type "print" at the jtag command prompt. Here is an output example:

jtag> print
 No. Manufacturer         Part                 Stepping Instruction          Register
----------------------------------------------------------------------------------------
   0 Intel                PXA250               C0       BYPASS               BR
jtag>

===> Third task: Sample device pin status.

jtag> instruction 0 SAMPLE/PRELOAD
jtag> shift ir
jtag> shift dr
jtag> dr 0
