Re: [ECOS] Can't connect to remote Evaluator 7T

Now I want to use RedBoot instead of Angel. I uploaded redboot.UU onto the board and then verified (using a communication program) that redboot was properly installed (see redboot banner below).

Possible, but unlikely since you're receiving stuff at all (packet errors, not just timeout) and I assume you have the baud rate right :-).

Before target remote you could do:

set debug remote 1

to see what that says. If that doesn't reveal anything interesting then (if I'm remembering right) you can also do:

set remotelogfile gdblog.txt

before the target remote, which should give a slightly more accurate version of what was sent/received, into the file gdblog.txt.
