I debug ov5640 camera by csi with imx6ull.under rgb565 mode,

The mclk wave as:

687845078.jpg

and the pclk wave as:

446188102.jpg

and the href signal wave as:

260534144.jpg

I wonder are these wave forms right?

And when the dma request bit (BIT12) enabled in CSI_CSICR3 reg. after i start csi , the system get stuck. I put some print code in CSI isr, but nothing can print.

is there something maybe wrong ?

After I use physics address in these registers, the stock problem has solved.
