OpenOCD forum moved, and some updates

The forum system at Berlios is a bit unhandy to use – at least when you’re used to the features offered by other systems. Tsvetan from Olimex has been kind enough to ask Sparkfun to host the OpenOCD forum, and they’ve just set up a new section at their forum. Thanks to both Tsvetan and Sparkfun. The new place to ask for help with OpenOCD, to discuss new features you’d like to have, or just to let everyone know what you think about OpenOCD is http://www.sparkfun.com/cgi-bin/phpbb/viewforum.php?f=18.

The support for Intel XScale based devices is coming along nicely. So far uploading the debug handler, entry into debug, core register handling and memory access works. Working with the XScale requires the ability to identify some ARM instructions, to be able to calculate the next address that’s going to be executed. I decided to add a complete disassembler to the OpenOCD, which is now (trunk, revision 68) available from the telnet interface:
