UART custom AXI4 Lite IP

MATRIX7878
MATRIX7878 4 months ago

Hello,

     I am creating a custom IP for a UART for my ZuBoard 1CG.  I am not sure how to complete the AXI4 files both the wrapper and the slave file.  I have looked for guides and none have helped me.  I tried the ZuBoard training and that did not help either.  Does anyone have any examples? or any guides to help me please?

Thank you

    I published an example for a simple custom SPI driver that can help you. Look for "Creating an AXI-Lite IP block" for the driver section. Blog 4 - FruitVision Scale - FPGA-Based HX711 Driver for Precision…

    Forgive me I am still trying to get a better grasp on SoC fundamentals., I will try to explain better.  What I want to do is create my own IP for the UARTLITE.  I want to use the dedicated UART pins (M10 and M11) with my own AXI4 IP.  I want to use the UART program I created for the ZuBoard to utilize.  That way I can create my own functions in Vitis to display.  I know it sounds like a lot of extra work; on the other hand, I want to make as much original designs as possible.  What's the fun in just using premade IPs?  Essentially, I am trying to remake the wheel with my own version of the code.  I hope that makes more sense.
