Easier to do that just using the "length" parameter ... though EmbeddedICE has a "range" mechanism, it ties up both bp/wp units. > Specifically this can be useful to e.g. catch breakpoints to *all* vectors. ... that's what the vector catch hardware does. Pretty much all ARMs except some ARM7 chips have that. ARM7 can do more or less the same thing by using a "length" of 8 words, which covers the entire vector table. (Though of course, breaking on the IRQ vector would make trouble!) _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
