Hello folks, Software v2020.1 Hardware: Zedboard + FMC + PCAM for Port A
I am trying to get an example setup running with the MIPI CSI 2 RX subsystem connected to the Video Frame Buffer to read it.
See the following diagram
As I export the hardware to Vitis to create the device tree files, the pl.dtsi is generated as shown below. It can be seen that in mipi_csi2_rx_subsystem_0 the ports entry is not created.
What I would expect are entries like:
Quote
csiss_ports: ports {
#address-cells = <1>;
#size-cells = <0>;
csiss_port0: port@0 {
/* Fill cfa-pattern=rggb for raw data types, other fields video-format and video-width user needs to fill */
reg = <0>;
xlnx,cfa-pattern = "rggb";
xlnx,video-format = <12>;
xlnx,video-width = <8>;
csiss_out: endpoint {
remote-endpoint = <&demosaic_in>;
};
};
csiss_port1: port@1 {
/* Fill cfa-pattern=rggb for raw data types, other fields video-format,video-width user needs to fill */
/* User need to add something like remote-endpoint=<&out> under the node csiss_in:endpoint */
reg = <1>;
xlnx,cfa-pattern = "rggb";;
xlnx,video-format = <12>;
xlnx,video-width = <8>;
csiss_in: endpoint {
};
};
};
};
demosaic_ports: ports {
#address-cells = <1>;
#size-cells = <0>;
demosaic_port0: port@0 {
/* For cfa-pattern=rggb user needs to fill as per BAYER format */
reg = <0>;
xlnx,cfa-pattern = "rggb";
xlnx,video-width = <8>;
demosaic_in: endpoint {
remote-endpoint = <&csiss_out>;

What went wrong? however as it is autogenerated and the hardware design will be used later for PetaLinux.
does anyone has worked with new version mipi core to help me on understanding the issue?
Thank you in advance!
