H-Jtag - not detecting hardware

Alpesh
I have Friendly ARM mini 24440 board. I have connected the Hardware to
system as mentioned in Manual. But H-Jtag server is not detecting the
Hardware.

What should be the problem ?

Pls, tell me.

Operations -> Detect target

Have you got "Updating the boot loader to NOR with JTAG"

found at www.andahammer.com

> What should be the problem ?

* JTAG settings
* LPT port address

Do you use the "Download Manual" from the download page?

Ar you using a real LPT port or an usb->lpt.
Last one won't work.

I also have the same problem, H-Jtag Server says "Unable to find target. 
Please make sure that the hardware is properly connected and powered up."

I have also tried sjf2440 on windows and sjf2410 on Ubuntu 9.10 and neither
recognize the board. I have tried many different settings and options and
cannot get my board recognized.

I am wondering if maybe there is a problem with my Mini-JTAG adaptor or my
mini2440 because I used my parallel port a few days ago to flash firmware
on another device through JTAG.

I have seen the files you mentioned somewhere, but my H-Jtag seem to use a
   FriendlyARM2440.his
and a 
   H-Flasher_mini2440.hfc
file.

Has it ever worked?

I have tried following the instructions in the "JTAGing the NOR" PDF at
andahammer.com and have also used the "FriendlyARM2440.his" and
"H-Flasher_mini2440.hfc" configuration files but my board device isn't
recognized.

I have had it for about a year and have never used the JTAG on it because
supervivi was fine for me.  I will be testing out my JTAG-MINI board to
make sure that the octal buffer chip is working correctly, otherwise I will
have to make do with supervivi on the NOR.  Or maybe I can find another way
to update the NOR :)

Just a long shot:

- the last time I used it I had a bit of trouble getting it going.

The instructions say to power up the mini2440 and THEN launch H_JTAG.exe

I recall having to do something different in the start up sequence, try
launching H-JAG.exe and then powering up the mini2440.  Try both ways
several times.  And try SETTINGS -> JTAG SETTINGS -> USER DEFINED as on
page 2.

A new JTAG board must be pretty cheap, if you can find a source. 

Good luck!

I finally got it working!  I tested the continuity of the ribbon cable from
the JTAG board to the mini2440, tested the voltages on the mini2440 JTAG
port, tested the functioning of the octal buffer on the JTAG board and
everything seemed to work fine.

I also noticed that the cable headers are not snug on both ends of the
ribbon cable, so I tried it one last time. I connected the cable snugly on
both ends, and finally my board was recognized!  Tried it a few times just
to make sure.

So I guess the moral of the story is to make sure the cable is connected
snugly because it seems pretty loose and easy to come out of the pin
header.

Good going, got there in the end.

Telling us the outcome just might be helpful to others.
