MPC5554 internal FLASH error

During the execution of my software the internal FLASH of the MPC5554 is became unreadable (Bus error using TRACE32 debugger). I do not know this can be possible as my software should not have executed any function to ERASE/WRITE the flash.


The unreadable FLASH is from address 0xD0000 to 0x1C0000. My software was not executed into one of this bloc of FLASH.


Do someone know which actions can set the FLASH into an invalid value ?
