Hello,

I'm using DVR RDK 4.1.0.2 with DM8148, does it mean that the u-boot version is 4.1.0.2 ? 
According to link
http://processors.wiki.ti.com/index.php/TI814x-DDR3-Init-U-Boot_Wordwise_SWleveling
I should add specific patch for 4.1.0.2 (I guess I can ignore step 3 below). Is that Right ?

Prerequisites

1. Excel spreadsheet for obtaining the seed values which is the input to the CCS based app File:RatioSeed TI814x.zip
2. CCS based program DDR3_slave_ratio_search_TI814x.out File:DDR3 slave ratio search TI814x.zip
3. TI814x U-Boot source code based on PSP release 04.01.00.06
4. U-Boot-DDR3_TI814x.patch File:U-Boot-DDR3 TI814x.patch (Only if you are using u-boot release 04.01.00.02

Regards,
Ran
