ZynqMP DDR Testing was failed.

Hi,

I am testing DDR memory on Zynq UltraScale + SoC system. Component type memory was used. (DDR4 MT40A512M16, -62E, 4EA)

So, I ran a DDR test program in XSDK and I am getting errors in certain areas and certain lane. (0x3FFFE000 ~ 0x3FFFFFFF / Lane 6, 7)

DDR Test Result is below..

However, It works fine in other area. ( ex, 0x30000000 / 0x40000000 )
