How do I intercept signal handler messages ??? I like and put debugging info on a LCD with my own custom function. I would halt the debugger when I get there.
Currently, I have my own HardFault_Handler that prints a few registers on my LCD. I am having crashes at the function pbuf_copy from LWIP and the call stack gives me the following:
V71myapp.elf! HardFault_Handler Line: 1252
V71myapp.elf! <signal handler called> Line 1252
V71myapp.elf! ??? Line 1252
V71myapp.elf! pbuf_copy(struct pbuf* p_to, struct pbuf*p_from) Line 855
V71myapp.elf! ??? Line 855
Is there already a signal handler or not provided??? Am I getting a HardFault because I have no signal handler and it by default goes to the Hard Fault??? Is there an easy way for me to see more information like the signal number??
