DRAM INITIALIZATION

Postby mariya pradeep » Thu Nov 17, 2016 1:19 pm

Hi,
I am working on wandboard imx6 dual, I was able to write and read a value to a ram location 0x12000000 using md and mw commands. But once the board was reboot via software the value resets and gets back to the initial value. Why it happens so,is it the actual behavior. Also I would like to know where dram initialization takes place.

Thanks in advance.

The DDR init is done by u-boot. You should look at the source code for the Wandboard's version of u-boot.
