I'm using MPC5744, it works fine for a long time. But today something just go wrong, when PIT triggerd interrupt, the process stuck! From debugging I find that pc stuck at address 0x00FA2010, this is an adress so called "IVOR1_Vector". it is someting relative to interrupt process.
The datasheet said in software vector mode, interrupt should go to "IVOR4_Vector", but not "IVOR1_Vector".
I did some mod on the INTC code, sometimes it also stuck at 0x00FA2060, whitch is "IVOR6_Vector", such as when I change it to "Hardware vector mode."
Before today, everything just goes fine. I don't know why this happens.
Who can tell why the interrupt goes to 0x00FA2010 or 0x00FA2060?
Waiting for an answer.
Noticed: No source available for "IVOR1_Vector() at 0xfa2010"
