Using an MT25L Flash with Kintex Ultrascale Plus

I have a Kintex Ultrascale Plus design (XCKU11P) using an MT25L Flash (3.3V part) with level translators to interface to the 1.8V SPI boot circuit but the Vivado Lab tool tells me that only MT25QU (1.8V parts) are compatible and will not program the part (it does gladly erase it).  Is there a way to work around this issue?

Thanks for any help ...

Re: Using an MT25L Flash with Kintex Ultrascale Plus

Hi @mlevro ,

Only Flash listed in Configuration memory support of UG908( vivado version) are officially supported and Vivado can only program those flashes. if your current Flash part name is not in that list, then you can't program that flash through Vivado.

If your Flash part number is not in the list of UG908(Viavdo version), you can still program the Flash through Third party programmers and then you need to ensure that Command sets of your Flash should match with the command sets of one of the supported flashes listed in UG908. Then you can succesfully configure the FPGA with the help of unsupported flash.

Hope this helps.
