Xilinx AXI quad SPI post configuration flash programming

[boyerkg]

Hi All,

I was wondering if anyone has successfully implemented a post configuration quad SPI flash Xilinx programming without micro processor?

I am using the Xilinx Artix-7, and I want to reprogram a new .mcs file into flash using an existing data path: not the Xilinx tools.  I would also like to know how to connect to the existing SPI flash pins.

I instantiated the axi_quad_spi IP, and it doesn't show how to simply us it.  The Xilinx project seems incomplete.

Any help would be appreciated.

Hi @boyerkg,

The How To Store Your SDK Project in SPI Flash tutorial shows how to program the flash using SDK. Is this kind of what you are looking for? Could you be more specific about how you are wanting to program the flash?

cheers,

Jon

Hi Jon,

I want to re-load a new FPGA image into the flash after the original design has been loaded into flash.  The original flash will be loaded using Xilinx Vivado and their flash load hardware.

Essentially, I want to take over the Xilinx hardware and load a .mcs bit file through our user data path to program flash.  After reset, this new image will be loaded in the usual way from flash to the Artix-7 fpga.

Hi @boyerkg,

Unfortunately, I have not reconfigured the flash using a flash design. I have a xilinx forum thread on partial-reconfiguration here and a xilinx forum thread discussing reconfiguration of flash here.

cheers,

Jon
