jtag and port help

[jammoboss]

Since upgrading my computers motherboard i have not needed to use jtag but i do now, the problem is with the circuit i got with the jtag leads its a 25 pin port which i dont have on the motherboard.

I tried buying a 25 pin to usb adaptor but that failed and could not get a connection through ocd or bke2.2.

Is anyone else jtaging any other way that doesnt have a 25 pin connction.

thanks

Probably find that you have a 25 pin connector on your motherboard jammoboss. Would be best to try and find a bracket mate.

if you get stuck and you dont mine sending i'll sort it for you and return m8

Nice mb mate but couldn't see a port on it. Another option is to use a pci port which is slightly more expensive. Here's an example

thanks for the offer mate, i dont jtag oftern so i completely forgot when i upgraded my motherboard 6 months ago.

chookey thanks for the reply but the lead i got is the 25 pin.

would this work?

p.s

I know this should be in the pc section but my machine sometimes wont boot up, it turns on but my monitor gets no signal so i have to out it and try again until i hear the beep. Could it be a hard drive problem?
thanks

Yes mate and cheaper than the one I posted. By the way, my link was for the db25. Probably just show db9 for illustration purposes.

Watch out !!!! You have to make sure that the card supports legacy adderssing, i.e. the // port can be set to I/O address 378. Most if not all new cards only support memory addressing i.e. FCD0 etc. They will NOT work with any of out Jtagging software.
A quick search through Moschips site suggests the 9835 chipset doesn't allow remapping in XP/NT/200/Vista

hi again all

well ive lent a mates old laptop with the 25 pin connection and im trying to use bke 2.2 but when i run mac_mot.sys in the backround im not able to get the readings im getting "Target communication error: unable to put target into backround".

I have tried and tried and cant even get ocd to install on this laptop.

whats this error mean?

its sorted now

Try it with the JTAG connected directly in the back of the laptop. that will eliminate a wrong printer port cable....
