Hello, I have been testing my code for thread stack isolation against various tests( Some written by me, and remaining already present). One of the limitations that I have found is that I encounter fatal errors whenever a context switch takes place through an ISR. Can you please explain how the context switching procedure works when an interrupt occurs. When I use gdb for stepping through the code it asynchronously moves to context switching code from the executing thread( for example psx16 test). For thread stack protection, the part that deals with context switching simply 'sets 'the memory entries of the heir stack and 'unsets' that of the executing stack.
