Does anyone know the design consideration for using 32bit LPDDR2 with IMX6UL? The IMX6UL has 16bit controller and can support the LPDDR2.
However in my design I need to use MCP package (LPDDR2+eMMC) to save the space. 16bit LPDDR2 chips are not common in MCP package and usually they are in 32bit configuration.
There are several MCP packages from micron with 32bit LPDDR2 and they claim that it will support 16bit configuration. So, is there any document or design guide for boot configuration and layout.
