I am using RRU SC667463  controller

I am facing machine exception , but looking at the stack frame from local and looking into the registers 

i am not able to figure out why it is exactly happening, it is very much random behavior 

 

 

I can see the Link register to be FFF0000, which shlould hold the return address but its illegal address.

Looking at MCSRR0 i can see FA3234 which is the content of the return address for isr

 

 

 

I am trying to figure out the exact reason behind the random exception but i am not able to map it correctly.

 

Regards,

Nishesh
