Shared memory usage in MPC5746C

[jayasankar_band]

Hello,

I am working on MPC5746C MCU and recently I have declared a shared memory regions in SRAM memory section. 

When I use "memset" function to reset the memory region, it is causing an exception and leading to an ISR.

The object declaration is as shown below.

Is this the correct way ? Any mistake in declaring and processing the shared memory ?

Hi,

the snippet of your shared memory section seems to be correct.

Please check in the map file the object ShmMsgToCore1 is placed at valid address 0x4007C800.

I assume the entire SRAM is initialized by the startup to avoid ECC exceptions by core0.

Could you possibly narrow it down to which specific instruction/core  is causing the exception?

Is it indeed memset() or some other following statement?

 Also you might be interested in this example:

Hope it helps.
