JTAG software

Post by mstombs » Thu Nov 11, 2010 10:28 pm

The original OpenWRT HairyDairyMaid JTAG software WRT54G does work with Ti AR7 via CUSTOM configuration options using the very poormans XILINX buffered parallel port cable - see viewtopic.php?p=15363#p15363. I am still using the same cable and the same test router, but have since repaired a second ADSL2MUE and now a DG834GV3.

The WRT54G routines have been incorporated into other tools, for example Ciclamab, a Thomson Speedtouch version stjtag and Igor Mokrushin aka McMCC also created a version for Acorp pspboot routers.

The JTAG software is still in active development by Tornado on ddwrt forums as tjtag,
http://www.dd-wrt.com/phpBB2/viewtopic.php?t=22655
and it now identifies and programs many different routers and flash chips.
I have found it works fine on my routers, but only in custom mode with long command lines, so I have applied McMCC patches to the latest version tjtag3-0-1 for which source-code released, to make it more Ti AR7 friendly. I am using the Linux version under 64 bit Ubuntu, but have also compiled and using a Linux 32 bit version for example here (should be straightforward to compile the windows version...):-

To run the program in this OS you must stop a printer task grabbing the parallel port using

Code: Select all

sudo rmmod lp
Then running the tool without parameters gives this help text:-

Code: Select all

tjtag3-0-1/linux_32bit$ ./rtjtag32

==============================================
 EJTAG Debrick Utility v3.0.1 Tornado-MOD 
==============================================

 ABOUT: This program reads/writes flash memory on the WRT54G/GS and
        compatible routers via EJTAG using either DMA Access routines
        or PrAcc routines (slower/more compatible).  Processor chips
        supported in this version include the following chips:

 NOTES: 1) If 'flashing' - the source filename must exist as follows:
           CFE.BIN, NVRAM.BIN, KERNEL.BIN, WHOLEFLASH.BIN or CUSTOM.BIN
           BSP.BIN

...........or for Ti AR7 MTD2.BIN, MTD3.BIN

        2) If you have difficulty auto-detecting a particular flash part
           you can manually specify your exact part using the /fc:XX option.

        3) If you have difficulty with the older bcm47xx chips or when no CFE
           is currently active/operational you may want to try both the
           /noreset and /nobreak command line options together.  Some bcm47xx
           chips *may* always require both these options to function properly.

        4) When using this utility, usually it is best to type the command line
           out, then plug in the router, and then hit <ENTER> quickly to avoid
           the CPUs watchdog interfering with the EJTAG operations.

        5) /bypass - enables Unlock bypass command for some AMD/Spansion type
           flashes, it also disables polling

 ***************************************************************************
 * Flashing the KERNEL or WHOLEFLASH will take a very long time using JTAG *
 * via this utility.  You are better off flashing the CFE & NVRAM files    *
 * & then using the normal TFTP method to flash the KERNEL via ethernet.   *
 ***************************************************************************
and you can see the AR7 bits I added. Note mtd4 and FULL access is also programmed, it should adjust to the flash chip size but not yet tested - too slow to be any use?

NOTE mtd3 is the PSPBOOT config, not the adam2 one which is at the end of the flash memory.

This version of the software will detect the Ti AR7 CPU and look in the correct place for the flash chip so few extra params needed - note "sudo" required to run this as root under Ubuntu.

if it works for you then please thank Tornado - if i broke it, sorry, I'll try to fix - but no guarantees!

Please see original download for documentation - I've not updated it, Windoze port to follow

And this a version compiled with MS Studio 2003 on XP.
Needed a couple of missing header files, and minor change to c routine to compile with "cl"

Usage: see original docs, must first load and activate giveio.sys using Loaddrv.exe

basic check it works:-
