RE: RE: J-Link errors on initial installation

2005-12-14 by Steve Franks

Joel,

Did all that. Light is solid, rebooted machine, deleted & re-installed
latest driver from segger site, etc.  Figure the box is just fried?  It's
been in the dev-kit box unused for a year...but it was in a cool, dark,
ESD-controlled place.

From the error messages, it looks like jlink.exe is about to load the
firmware, but keeps getting bogus string sizes for the fw update.  Tried
several usb cables.  I just thought someone might of seen this, but if not,
I think I'll assume it's DOA.

Thanks,

Steve
