  1. I need a urgent help regarding this, Please help me, I booted my board with 5V wall connector and when i connect micro usb to laptop com port is not detected, i tried with different laptops too still did not work. I have added USB 0 in my design and it seems petalinux booted just fine since i can see PGOOD and DONE LEDs are on and my counter is running. I even tried different cables install drivers manually, I can see my petalinux booted and as soon as i turn on my RX led blinks for some time and then stops and board LED and Switches works as i configured. But COM port is not detected. I Tried different PC as well. nothing works. Please let me know the solution. Please do help.
  2. I want to use PmodIOXP to allow both PmodAQS and PmodHYGRO to be connected into the same port in Zybo Z720. However, I do not know how to write my block design in Vivado since there is no IP for PmodIOXP in the vivado-library. Also, what kind of C++ code should I write in my Vitis after I exported my vivado file into Vitis
  3. Hello, I am working on video processing using Z7-20 Pcam 5c, for this I have created an IP block which converts rgb image to hsv. Now, I want to filter it to obtain only the yellow color. So for this I am trying to use the hls::range function to threshold the pixels in the range of yellow color. As per the manual, the template is as follows: template<int ROWS, int COLS, int SRC_T, int DST_T, typename P_T> void hls::Range ( hls::Mat<ROWS, COLS, SRC_T>& src, hls::Mat<ROWS, COLS, DST_T>& dst, P_T start, P_T end); I want to understand what does typename P_T mean and how to define it in the header file. I am getting the following error with the current code that I have written C:/xilinx/Vivado/2017.4/include/hls/hls_video_arithm.h: In function 'void hls::Range(hls::Mat<ROWS, COLS, SRC1_T>&, hls::Mat<ROWS, COLS, SRC2_T>&, P_T, P_T) [with int ROWS = 720, int COLS = 1280, int SRC_T = 4096, int DST_T = 4096, P_T = hls::Scalar<3, unsigned char>]': ../../../yellow_threshold.cpp:24:32: instantiated from here C:/xilinx/Vivado/2017.4/include/hls/hls_video_arithm.h:1042:22: error: conversion from 'hls::Scalar<3, unsigned char>' to non-scalar type 'hls::_AP_T {aka ap_fixed<64, 32, (ap_q_mode)0u>}' requested make: *** [obj/yellow_threshold.o] Error 1 ERROR: [SIM 211-100] 'csim_design' failed: compilation error(s) Please find the attached files for more details and suggest me how can I proceed.
