Hello, I'm using a Zybo Z7-20 board together with the Pcam 5C camera module and I have a question regarding the MIPI D-PHY settings in the Zybo-Z7-20-pcam-5c project. I want to replace the Digilent MIPI_D_PHY_RX with the Xilinx MIPI D-DPHY. My issue is, that the Xilinx MIPI D-PHY does not output any AXI-Stream signals and that I see permanent 'Start-of-Transmission (SoT) Error' (errsoths = '1') reported on the output port of the Xilinx MIPI D-PHY. This error occurs, according to the Xilinx MIPI D-PHY datasheet, when the HS_SETTLE parameter is not matching. The standard HS_SETTLE parameter in the Xilinx MIPI D-PHY is 145ns. The DPHY_LaneSFEN.vhd file, which is part of the Digilent MIPI D-PHY, uses a constant named 'kTHSSettle' which is set to 85ns. Even if I setup the Xilinx MIPI D-PHY to use a HS_SETTLE time of 85ns, I still see the 'Start-of-Transmission Error' reported by the Xilinx MIPI D-PHY. The camera setup is done by the Digilent pcam_vdma_hdmi application which configures the camera to run in the standard 1080p30 setup mode (2-MIPI lanes, with 420 Mbps/lane). What are the settings for the Xilinx MIPI D-PHY to decode the 2-lane MIPI signal received from the PCAM 5c camera board?
Hi! I'm using a PCAM5C with Zybo Z720 revision platform on SDSoC. Right now I'm using filter2D for PCam5C and I've seen that the default format is a multi-planar, two-plane version of the YUV 4:2:2 format, and when they apply the filter2d they just use the Y plane. I wanted to know if anyone could help me with changing this format into RGB because I want to use in the filter2d.cpp the cvtColor to transform the RGB 3channels into 1 grayscale. Or if maybe there's a conversion between YUV4:2:2 and RGB by using the two planes? Thanks so much!!
