Hi there, Just in case somebody is scratching his head with this too, I've worked out that the problem is the usage of the --detach option.
If I omit it, then I can connect just fine running avr-gdb in a separate process (xterm window). I was trying to do it as per the avarice script ice-gdb that uses the --detach option so that it does not need to keep the console where avarice was started busy. Why --detach causes this problem? No idea... good to know why, or if the ice-gdb script is wrong. Regards David PS. The digest emails from this mailing list, and avr-gcc too, seem to not appear as attachement to thunderbird, so replying becomes a bit involved. Thank god, I can highlite/select the text in the digest email, then hit reply, but it would be nice if they came as in sourceware mailing lists... just saying. :-) On 12/02/14 17:51, avarice-user-requ...@lists.sourceforge.net wrote: > ------------------------------ > > Message: 4 > Date: Wed, 12 Feb 2014 17:39:04 +0000 > From: David Fernandez<dfernan...@solarflare.com> > Subject: [AVaRICE-user] Timeout reading memory when connecting to > ATxMEGA16A4U > To:<avarice-user@lists.sourceforge.net> > Message-ID:<52fbb1b8.5000...@solarflare.com> > Content-Type: text/plain; charset="iso-8859-1" > > Hi there, > > I'm trying to debug with avr-gdb and avarice. > > Initially, I've tried just to connect to target and see what can be seen. > > It seems that avr-gdb can't read what it needs from avarice quite > straight away. > > [root@df-desktop ~]# avarice --debug --jtag3 --jtag usb --pdi > localhost:6423 --detach >avarice-debug.txt 2>&1 > [root@df-desktop ~]# avr-gdb > GNU gdb (GDB) 7.6.50.20131021-cvs > Copyright (C) 2013 Free Software Foundation, Inc. > License GPLv3+: GNU GPL version 3 or later > <http://gnu.org/licenses/gpl.html> > This is free software: you are free to change and redistribute it. > There is NO WARRANTY, to the extent permitted by law.
