I am using mpc5748g and my application need ETH module. But I met an problem, my software always enter IVOR1 interrupt when startup. After checking for several hours I found that the generated assemble source code used e_sth op-code to write register value. Then I modified my C source code. But now my software still enter into IVOR1 interrupt. My question is:
how to position the root cause once software enter into IVOR1 interrupt?
