How to perform read and write to pl ddr

hi,

i have created a design for 5ev-1 with 1 gb pl ddr .the address editor shows 8000_0000 as starting address and high address is 9fff_ffff.

when i use wr or wd or mtest command in uboot ,the cpu resets itself.read and write to this address is not possible.

what is the reason ?and how can i read and write to pl ddr?

Regards,
