Where can we find interfaces to JTAG? i am trying to configure Virtex
-II FPGA w/out using any softwares. The project requires me to write my
own software in C to download the bit file to the device.. what kind of
interfaces are needed for this.. i am using Windows as a platform

Now what is it, "code runs slower" or "system crashes"? You do have the JTAG lines properly pulled up and down with resistors so TMS=1 and nTRST=0 when the JTAG is not connected? If not, that could cause this problem. Regards, Arie de Muynck

Are you using any output to the term.view in trace32, that usualy gives a lot of delay. -- Med venlig hilsen/mojn/regards Martin Hansen Center for Software Innovation Stenager 2, DK-6400 S�nderborg, Web: www.cfsi.dk

Hi,

it appears funny but interesting. I am debugging a problem and for
which I am using TRACE32 JTAG interface on ARM platform. But when I try
to run system without attaching JTAG it crashing where as at the same
time once i mount it on JTAG it runs smoothly

I observed that JTAG introduces some delay so i introduced some delays
at specific locations but still it is same ...

Anybody came across such problem .. your views will be really helpful
