It seems to work for me.

Final version of that patch being in http://lists.berlios.de/pipermail/openocd-development/2009-September/010369.html yes? That looked sane.

That was one objection; I think the "not merge" was more of an issue of "nobody really focussed on it". I was thinking that someone *else* would merge it. Sometimes you need to nag to get things merged... _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
