I don't know where to add the printf statement. Could you please guide me where to add the printf statement or add for me so that I can rebuild the urjtag.
Thanks for taking the interest.

I made this cable myself. But made it ina good way and tested by the multimeter. I don't have oscilloscpe.
Is there any way to test the cable and the connections. Is there any other way to test the signals between the PC and the device.
Thanks for the help.

Hi,
I know it is included in the Doc subdirectory. But my suggestion it to also include seperately so that people can read it.
Anyway for my problem. Detect doesn't do anything.
Thx.

I am sorry I didn't read the urjtag.txt file. I think this file should be with the bz2 file.
I then installed ioperm -i.
Now I don't get any error. But it doesn't do any thing either.
If you have time I was following the http://www.seattlewireless.net/LinksysWrv54g website for jtag. But this is not working for me.
You can close this case now.
Any way thx.

I was trying to compile on windows XP using Cygwin. It complains about libreadline.h, history.h. I tried to check these files, they are not available.
