Thanks, but that's not the problem - I know how to create a
port.

That's not the issue here - I was asking what other people on FreeBSD
use for their JTAG needs, seeing that OpenOCD isn't in ports I doubt
that is in widespread use among FreeBSD users (else, someone would
have submitted a port).

See http://www.macraigor.com/wiggler.htm - it's the de facto standard
when it comes to parallel port JTAG connections. It is supported by
both openwince-jtag and OpenOCD.

I use it for downloading new firmware images to devices and debugging
said firmware.
