K2HEVM DDR3 mapping?

John Cook34

The K2HEVM connects the Keystone2 DDR3A interface to a SODIMM and the DDR3B interface to soldered-in DDR chips. For U-Boot 2015.07 and Arago 2015.12 that SDK 2.00.11.02 provides, at which physical addresses does each of these DDR interfaces appear in the ARM address space and in the DSP address space?

Thanks,

Typically EMIFB is used for DSP and EMIFA is used for ARM.
You can check the physical address of EMIFA and EMIFB from data sheet.

I understand that typically EMIFA is for the ARM and EMIFB is for the DSP, but my question is for the specific case of K2HEVM with U-Boot 2015.07 and Arago 2015.12 that SDK 2.00.11.02 provides.

What is the ARM memory map for EMIFA with U-Boot 2015.07 and Arago 2015.12?

When the ARM runs U-Boot 2015.07 and Arago 2015.12, does it use EMIFB at all?

Thanks,
John
