Problems with newer (1.x) Versions

slemke

Hello,
I have problems using newer versions of zjtag.
My Setup:
- TIAO USB Multi Protocol Adapter (TUMPA)
- Target Device: WRT54GL
I am using v0.4 for a couple of devices without any problems. The command line switches are:
zjtag -flash:cfe /L1:4 /delay:100
With Version 1.0 (and also the latest 1.8) *and excatly the same setup* I get the following error when zjtag begins flashing:
dma write not correctly !!
0064696C - 00800080
I have also tried to play around with different command-line switches without success.
Can anybody help me? My goal is to modify the source so that pressing enter before start flashing is not needed anymore (so I can do batch processing), but I did not found an 0.4 source and the actual one does not work correctly for me?
Thanks,
Sebastian

Could you Please try versions newer than 1.0 and older than 1.8.
there is no need to use experimental 1.8 builds for WRTxx series.
Thanks!

If you want sources for zJTAG version 0.4 or 0.x ; contact me = volkan-k (at) users.sourceforge.net
Then i will send you source files.
BTW, You can contact Paul Fertser, he is openOCD developer & active user and he has TUMPA & TUMPA-Lite.
I believe he will help you to get OpenOCD batch script for WRT54GL. AFAIK; OpenOCD supports TUMPA, TUMPA-Lite and WRTxx series routers.
If you are interested, find him on FreeNode IRC server, #openocd channel. irc://chat.freenode.net/openocd
You can Connect now using Freenode webchat, no IRC client needed.
Alternatively you can e-mail him. His e-mail address is fercerpav (at) gmail.com
Please post feedback here after you solve your problem, for other users to benefit.

OpenOCD includes an easy-to-use script to facilitate mass-market devices recovery with JTAG.
For quickstart instructions run:
openocd -f tools/firmware-recovery.tcl -c firmware_help

Hi!
Thanks for your reply. Using OpenOCD is not an option for me at the moment, unfortunately I do not have actually the time to setup the environment for this. A few month ago, I played around with it, but without success - I remember there were some issues with the reset line – I guess it´s fixed now, but for now I have too less time to check this.
Nevertheless - a big thanks for the contact details - when I have a few more time, I will try OpenOCD again!
I have done a small check with the different versions of zjtag today. At first of all I updated the USB Driver to the latest version available (also tested it on a second PC) – without success.
Important notice – I have changed the flash chip on the board (but I am sure the soldering is correct, when using v0.4 everything works as expected, Bootloader comes up after flashing and Flashing the firmware is also no problem) – I am using an 16MB Intel Chip.
With 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 and 1.8RC3 I get the "dma write not correctly" error using this command:

zjtag-1.x -flash:cfe /L1:4 /delay:100

With Version 1.7 the CPU is not being detected:

Any ideas on this? I would like to use the most recent version to be “future-safe”

Thats why we keep old versions. If some version working for you, then use it.
We welcome any patch for zJTAG that may fix anything I broke in last versions.
But unfortunately I am NOT able to investigate codebase currently due to my time limitations and lack of development environment (I lost my old laptop's harddisk with all development environment)

Hi,
You are always welcome. Please Let me know if you need anything else.
PS. I re-uploaded 0.x files to SourceForge.net for other users/developers to benefit.;
http://sourceforge.net/projects/zjtag/files/v0.x/
Please Let us know any news about your work and bug finding. Feel free to send any ideas & patches.
Thanks!

A big thanks for the sources !!
At first I will check versions after 0.4 and before 1.0 for working or not working with the router. I will let you know, when I have found the problem.
