How to add a new flash family of vivado 2018.3

[hongyanhou]

Dear

FPGA:  Xilinx Kintex7 xc7k325t  ,  FLASH: cypress spansion s29ws256

   I want to know if I can autostart FPGA through cypress s29ws256 flash.

Now, vivado 2018.3 can not find this flash when programing,  is there a solution to this problem?

Thanks~

Hi,

Please see Appendix C, Table C-2 in the document below for the list of supported devices.

S29WS256 is not supported. We recommend to use S29GL family.

Thank you and Regards.

Hi

Thank you for your answer，our pcb used this unsupported flash and do not to change it.

Can I write a flash protocol using FPGA，and write the bin file to flash?

I want to know if there is a other checks between FPGA and flash when the flash restart to configure FPGA.

Thank you and good luck

Hi,

To access to parallel NOR Flash using Xilinx FPGA, the External Memory Controller IP (https://www.xilinx.com/products/intellectual-property/axi_emc.html) can be used.

However, we cannot suggest on how to write the bin file and checks between FPGA and Flash. These are more likely Xilinx questions.

Thank you.
