I have migrated the CMOS driver like ov2659 and didnot modify the VPFE driver.
Now,I have got the image but lost one line,there is no problem at CMOS output,because I have captured it using FPGA.
I think maybe I need modify the VPFE driver.I found something from the vpfe driver like this(am437x_isif.c),is it mean that it will ignore the first line pixel?
