Hi, thanks for the reply. Actually i am new to this concept, i have gone through the links which you have sent. How to write our own exception handlers into VSR is what i want to know. I want to implement this at Application level. Kernel exception is the default configuration as i understood from the document. It is given that VSRshould be written in assembly language for Application exception handler. Can you please clarify all my doubts and please can you provide me any example codes for this exception handlers if any which have already been implemented.
Regards,
Kalyani

If you want to handle hardware exceptions then you can either plug
your own routines into the VSR table or enable the kernel exception
delivery mechanism. Documentation for the former can be found here:
