Yocto meta-layer for MaaXBoard/Mini/Nano

This lab will document the process for running an application on the secondary real-time r5 processor (RPU1) using split mode.

Developed with Vivado 2022.1, these behavioral simulations show how to recover native video timing from an AXI4 Video Stream and how to convert natively timed video to AXI4 Streams using catalog IP blocks including the Video Tiiming Controller, AXI4 Stream to Video Out and Video In to AXI4 Stream IP. AXI4 Stream input video is simulated using a Video Test Pattern Generator and the AXI4 Video Stream Remapper IP to show how to convert from 2 pixels per clock to 1 pixel per clock.

Developed with Vivado 2022.1, these behavioral simulations show how to use the Video Test Pattern Generator and highlight how to control the test pattern generation framerate using a Video Timing Controller and Video In to AXI Stream conversion IP. The simulation simulations a QQVGA (160x120) resolution frame size, showing 4 frames generated as fast as the TPG can generate them at 25MHz bus clock, then shows 4 frames generated with 60fps refresh rate timine (1.944MHz Pixel Clock).

The example design can be used as a reference of how to properly instantiate the Video TPG in a block design and configure a Linux build to generate (and display) test patterns using GStreamer. Four test pattern generator configurations are provided:

(1) Free Running mode (2) Free Running mode with Colorspace Conversion and Scaling using the Video Processing Subsystem IP (3) Rate Controlled mode (4) Rate Controlled mode with Colorspace Conversion and Scaling using the Video Processing Subsystem IP
