Hello,

I am using TC277 and we are running out of Core0 RAM Memory. Can we use Core1/Core2 RAM for few Applications and still execute all the Application in Core0?
Thankyou for your support in advance.

Thanks,

Yes, and you also have 32 Kbyte of LMU RAM that could be used.

Thankyou for quick response. My main goal is to move Ethernet buffers from Core0 to Core1/2 and execute Eth Stack on Core0. I cannot use LMU RAM because as per my Autosar Stack limitation LMU cannot be used for Ethernet buffers.

And one more question... will there be any Functional safety limitation by doing the above.

There is no general Functional Safety issue with access to DSPR on any core.
