- copy to boot disk files BOOT.bin, devicetree.dtb, uImage, boot.py from folder "kernel Pynq 2.1 for boot partition". boot.py - Use at boot to blink by led on board using pynq overlay BOOT.bin - Binary boot file, which includes the Zynq bitstream, FirstStageBootLoader and U-boot uImage - Kernel image file devicetree.dtb - device tree blob
Run board from microsd and use SMB(\192.168.2.99) and jupyter by Ethernet 192.168.2.99 (login xilinx and passw xilinx )
- DMA overlay and module This overlay implements a AXI stream dma that transfers data from one address in the memory to another. It is based on the following reference:
Lauri's Blog - AXI Direct Memory Access : https://lauri.xn--vsandi-pxa.com/hdl/zynq/xilinx-dma.html
The dma overlay was designed in Vivado 2016.3. A python c extension was designed to pass data from python to the PL and back via the AXI dma, based on the c code in the above blog. This extension is currently supporting a max buffer length of 16K word (unit32).
The package is installed by copying the dma directory to the board (via the samba server), and executing inside the dma directory:
pip3.6 install .
The code of the dma package is based on Lauri's Blog above, as well as the following references:
