I am in the process of writing a handler for PABT and DABT handling. Most of the work is already in C (I'll post it here when done). I am seeing data aborts and would like to know where things are going wrong. Processor aborts occur sometimes too, though much less frequently. I haven't found a reference for a couple items, and was hoping somebody here might know the answers or at least where to find them. I need to know a) What are in each of the various ARM registers when DABT/PABT is invoked? b) How can I copy these registers into specific RAM addresses? Thanks in advance. Andy

(adress in flash) for the rest i don't know very much. > b) How can I copy these registers into specific RAM addresses? if you know the base adress of the register, i think you can juste have a pointer on it and copy it ? but if you don't want t o use stack (to move SP), you can put the pointer "register" to not use ram. But i'm not sure of anything here, i just speculate. Jonathan
