Hi,
My task is to make OMAP4430 receive a data from FPGA over the CCP2 camera interface, throughput > 100Mb/sec. FPGA acts here as a camera sensor following "SMIA 1.0 Part 2: CCP2 Specification".
Problem is that I cannot make the CSI22 COMPLEX_IO get RESET_DONE bit set after initialisation. The initialisation sequence is shown below.
Could you, please let me know is there any source code which does a full CCP2 initialisation.
