Making a bigger FFT In our last post we made an HLS project with the top function “fftTop”. In this article I’d like to change a few things around. First lets make the FFT much bigger. We are using an FPGA for this so it won’t bog down the processor at all, I want to …
UIO Drivers The UIO drivers are the ideal way to interface with your own FPGA blocks. Generally speaking FPGA blocks are going to be configured through a group of registers from software, and then data will be passed through them, either from an external interface, or through streams to/from an axi-dma block. We therefore …
Later on we are going to need to look at adding ubuntu so we can download packages and whatnot. Since there are kernel modules being built here I don’t think we can just drop in the ubuntu rootfs unchanged like in most tutorials. I wrote this largely as a log for myself to refer to …

While looking into this the only petalinux distros available were very very old. Furthermore no recent BSP files are available for Zybo Z7. To do this I’m following the tutorial here: Running Petalinux on Zynq SoC from scratch – Zybo board But since I’d like to have USB working we are going to add …

Vivado has an FFT IP that you can customize and instantiate. I was considering doing this and simply adding it to the block design, but the FFT block requires a stream for data, as well as a stream for configuration. I will be getting the data stream from a and AXI-DMA block. I’m sure there …
