Re: [AVaRICE-user] debugWire : debug slow...

[Armin O. <arm...@gm...>]

I assume you're on Linux?
I did the Tracing with Wireshark (http://wiki.wireshark.org/CaptureSetup/USB).
There you can set the time-display to "relative to previous captured
packet" (or similar) and then you can quickly see where the USB is hanging.

Hmm the DEBUGWIRE SYNC FAILD doesn't sound too good. When I'm downloading I
don't have to unplug. Maybe there is some problem with the DebugWire
communication alltogether. Do you have anything connected to Reset apart
from the AVR Dragon?

Cheers,
Armin

PS.: sorry missed the reply-all in the first response... so now back to the
