How to configure ddr for application

Hi ,

My Name is Prakash, i am using Zynq_7000 SOC board, the SW package Petalinux-2015.04

 

my HW board supports four modes:

1. operational mode.

2. Standby Mode.

3. Sleep mode 

4. Deep Sleep Mode.

 

when i am entering from Operational mode to Sleep mode and wake up from Sleep to operational mode then Some time DDR memory gets corrupted. (i am running the Test continuously ) .

 

My Question is :

1. when system waking up from Sleep to operational mode does DDR data gets initialized with default value?, if yes then

2. How can i configure DDR memory to use for special purpose (lets say i have to write 1k of data into some RAM address , then how can i confirue DDR so that no one can use this address)?

 

Please fill free to ask anything.

 

Regards,

Prakash
