Hello Nxp,

I am using IMX8 processor and working at M4 side. I am using Rpmsg protocol to communicate A35 - M4 and rpmsg shared memory is pointed to DDR memory. 

Before the Rpmsg driver initialization function is called I see there is lot of junk values on DDR shared memory.
My question is 
1) this Junk values will cause any effect on the message tx or rx ?
2) Do I need to clear the shared memory to zero before the rpmsg driver is initialized?

 

Thanks
