Synchronization Between CortexA and CortexM

M.Eladouly

Hello,

I'm working with a bare-metal application running on i.MX8 (QuadCore CortexA35 & Single Core CortexM4).

Currently, I use Load/Store executive assembly instructions along with memory attributes for the MMU to synchronize between the CortexA cores.

My question is, is there a similar technique to synchronize between the A35 cores and the M4 core? Or this is a vendor specific mechanism that shall be used (NXP in our case)?

Thank you.
