Not handy, no; it surprised me too. ISTR there was a register controlling this behavior, and it seemed to be part of debug support. On the other hand, some non-microcontroller SoCs I've used take a different approach and have a formal controller dedicated to reset handling, which doesn't hook up to NSRST but offers per-peripheral controls over reset sequencing. On those SoCs, NSRST isn't a very widely used signal; affects only CPU cores. Debuggers and boot code are expected to talk to the reset controller as needed during bringup. - Dave _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
