Hello~~
i try to modify CPU & DDR speed from DM365 to DM368 settings by : http://processors.wiki.ti.com/index.php/DM36x_to_DM368_NAND_UBL_porting_guide and then result is no video output, the log is as below:

It seems the DM368 UBL settings affects the fps values, what others settings should i notice ?
