I've just started using VisualDSP and the BlackFin. My host computer
is a 1.4GHz P4 running WinXP and using USB to communicate with the
BF533 EZ-KIT LITE.
Everything works, but it is really, really slow!
- It takes about 6 seconds to run to the next breakpoint, even if
that breakpoint is on the next line.
- It takes at least 1 full second to step over a simple variable
assignment.
- It takes almost 3 seconds to step in to a function.
- Console output takes at least 1 second per line for "stdout" and
the same _per_character_ for stderr.
The disk light is off, so I know there's no thrashing on the host.
Is this normal? Is there any way I can make it run faster?
Thanks in advance!

That's very fast compared to the original VisualDSP and RS-232 ICE. That
sometimes took a minute or more to catch up with a big application I was
developing. 8-(

Okay, so it's not just me. I'm used to working on an 8032 ICE (Signum
Systems -- absolutely the best 8032 ICE I've used) over the parallel
port and it only takes about 1/2 a second to step or 1 second to go to
the next breakpoint.
