thanks for reply

Put the clock in the camera comes out give data.(8bit)


So I made read clk and recived data.

However, the speed of reading data from a GPIO through the mmap was slow to 
solve 
the problem, but a problem occurred a slow in clock speed makes the 
BeagleBoard

So I have such a question.
