For some reason my original post and Leon's reply didn't make it here. I 
see them on the yahoo groups archive though.

So, What is the correct way to get a minimum JTAG setup working with the 
secondary JTAG port? Leon's connections are for the primary JTAG port.

Has anyone connected a wiggler to the secondary port with success? I see 
that noone has responded to Jim Beagley's post about problems with the 
secondary port.

Also, I read on the Philips forum that when using the primary JTAG port 
you lose the trace pins even if you aren't using them for trace, right? 
This would be a good reason for using the secondary port since I plan to 
keep those pins free for jtagging on the production boards.

DBGSEL needs to be pulled high to enable JTAG, but what state should 
RTCK be in? The documentation says that it is used to select the second 
JTAG port, but doesn't say how to do this.

Thanks,

Brian
