What is TJTAG
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).
You can get the latest copy of TJTAG from [here]
We no longer hosting tJTAG on our site. Tornado has been working on this project for 6+ years, we encourage you to send him a minimal donation of $5.00 for using his software. TJTAG can be downloaded from http://www.tjtag.com
Author
TJtag is a port of wrt54g originally written by HairyDairyMaid. Later on, Tornado added support for more chips, initial SPI support for some serial flash devices and other enhancements
If you like this program you can send him a donation via paypal:
or
you can donate a router to him. He can be contacted by email. His email address is in the TJTAG zip file.

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