Our current application is :
Camera Sensor+ 4PCS*DS90UB913+DS90UB964 +FPGA soluiton , and 4PCS*DS90UB913 were used as the DS90UB964 input source. Register configuration base on ds90ub964 official datasheet 8.4.19.3.1 section page 34;To meet our detail application ,we modified configuration 0x70, the data format is yuv422 8bit , configuration 0x7c, uses the low 8bit.
Debugging issue :
(1)4 channels RX port input, configuration of 0x21 register for basic synchronized forwarding mode, configuration of 0x20 for single-channel Rx port forwarding output, the image can be HDMI displayed, can read the data at the MIPI port. 0x22 register FWD_STS and 0x35 register CSI_STS indicate that the data has been synchronized. (2):4 channels RX port input, configuration of 0x21 register for basic synchronized forwarding mode, configuration of 0x20 for four Rx port forwarding output, the image is not displayed ,we can’t read the MIPI register, and FPGA also can’t receive data; 0x22 register FWD_STS and 0x35 register FWD_STS indicate the data without synchronization.
Our questions:
(1)I wonder how to configure DS90UB964 in basic synchronized forwarding mode ?
(2) In addition, for synchronized forwarding output, whether need sensor for frame synchronization? Can the synchronized forwarding work properly if it is not synchronized?
