Bi -71 means bulk in transfer error.
And I test on am5728, the camera works well.but when I turn off SDRAM controller interleaving mode,the camera on am5728 also report same error.
AM5718 only have emif1 can`t support memory interleaving.The memory bandwidth is lower than am5728? how I make the camera work on my custom am5718?
