OK. So it's not crippling while I fix it. Phew! :-) I have to give a bit of thought on how to best to profile this, i.e. to find the precise location of the culprit. Any ideas? Then I believe it will be a simple matter for me to fix it and we'll see if we won't actually end up with *better* numbers. -- Øyvind Harboe Embedded software and hardware consulting services http://consulting.zylin.com _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
