I use the PE tools chosen the download debug session  to download the SW, When first download sw successful, the sw run normal ,next step I stop the debug session, power off the mcu and power on mcu, chosen the attach debug session, it stop exception IVOR6.

My mcu is MPC5646B

According to AN5200.pdf and e200z4RM.pdf to analysis.

MCSR register is EXCP_ERR :1

MAV:1

MEA:1

IF:1

BUS_IRERR:1

MCAR register is 0x000400d0

MCSRR0 is 0

FEAR register is 0xdfecdb57.

So according to the AN5200.pdf  5.1.1 Machine Check Syndrome Register (MCSR)

it belong to the error"Error caused by attempt to execute of instruction affected by ECC multibit error sets
MCSR[MAV, IF, BUS_IRERR]."

as show below:

 

 Can you help how to analysis the  issue and find out the reason?

probably the PE attach tools cause or in actual   my source code is high risk ?

thanks very much!
