Hi, How to handle the exception if any type of exception occur? That means How to tackle exception in exception handler? Regards, Naresh
Hi Naresh, I assume you are referring to the Blackfin CPU. You probably already know about the Exception ID field in the SEQSTAT register to identify the type of exception so that the appropriate handler can be called (usually deferred to a lower IVG level). However, if an exception occurs while you are at the exception level, you have a core double fault. There is a bit in the SWRST register that enables a software reset on a Core Double Fault. Hope this helps.
