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 pa
Hi all, I download the "ZedBoard-FMC-Pcam-Adapter-Dual-Camera-2018.2-1" and open it on vivado 2018. There are four MIPI D-PHY (A,B,C,D). In #A, we have a RxByteClk = 84MHz, which can be derived from total data rate =1344Mbps. However, when i check the configuration of #B,#C,#D, all of them have RxByteClk = 25MHz. Can I know how the difference or how the 25MHz be derived? Thanks. BR
I'm trying to understand how to set up clocks and read data from a MIPI camera sensor. The sensor (Omnivision 5647) uses the MIPI CSI-2 protocol with D-PHY for the physical layer. The stage I am trying to get to is to be able to observer SoT (Start of Transmission) signals after which I can start parsing the CSI-2 protocol packets. In a small MIPI writeup located at http://archive.eetasia.com/www.eetasia.com/ART_8800715969_499489_TA_a466fca2_3.HTM there are 2 statements that are to be taken into consideration when trying to read data: "The high speed payload data from the transmitter i
