Right. That's sort-of-explained in the ARM920t reference manual. I thought I had added comments identifying the relevant tables, but evidently not ... they certainly aren't in the source code right now. > I will try to use another cp15 access method! What's not explained, as I recall, is just *why* there are so many access methods. Surely it ought to suffice to just execute the darn instruction! I suspect that since this all dates from relatively early days of ARM9 cores, the engineers didn't have very clean models for how this stuff would get used ... so the result was a mess, instead of something that's easy to explain, use, and understand. _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
