questions about 8148 DDR init

guiguan bee

Hi all,

About the 8148 DDR init, I have gone through the description at:http://processors.wiki.ti.com/index.php/TI814x-DDR3-Init-U-Boot

My question is, how can I get the optimal values whithout JTAG connection to 8148?

Is there any other approach? On my board, linux can work

Guiguan,

I do not think you can get these values without JTAG connection.

The DDR3_SlaveRatio_ByteWiseSearch_TI814x.out file is CCS executable file and can be loaded only through the JTAG.

Regards,
Pavel
