You can find some guidance on setting up the SDRC registers here: http://processors.wiki.ti.com/index.php/Setting_up_AM37x_SDRC_registers

hello,

You need to ensure that you are setting up the config registers for both CS if you are using both. The DDR connect diagram you proviced is not readable. You should be able to get up and running by ensuring all of the registers provided in the wiki article that James provided. You might want to relax the AC timing values that you get from the calc tool.
