Our software running on the MPC5777M, our software utilize the AUTOSAR platform which the Autosar OS running. Our software normally run flawlessly, however, in some very rare circumstance that I don't know what it is, the OS report a MEMORY protection issue, indicate that our software access the illegal memory. We have traced down to the MCU and found that the MEMU record an address in SYS_RAM_UNCERR_ADDR, the address here is exactly where the OS report. However I believe the address in this register shall be the address in RAM. I want to note that address in an constant variable in the MCAL WDG module which we access it very frequently.
So my question is:
What is the significant of the the address in the SYS_RAM_UNCERR_ADDR, especially when it is an adddress in Flash memory?
