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.
