question about using the DDR_PLL of DM 8168

Hi,

My DDR3 can't work stable on the the 675MHz and the 796MHz, now, it can work stable on the 531MHz, however, it is unacceptable to us.

Now, I want to adjust the PLL of DDR, and I found some setting in the gel file of TI816x_ddr3 from the web site:

http://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_DDR3_Init, for example 702MHz, 729Mhz ...

I try the DDR_PLL setting in the file, however, the DDR can't work stably.

Could you provide me some other settings of DDR_PLL, I hope the DDR frequency between 675Mhz and 796Mhz.

Regards,

Tianxing
