SPI flash program on KC705

Jump to solution

Hi,

 

I got a confusing issue when I tried to program the SPI flash of my KC705. On the UG810 datasheet, the SPI flash is written to be 2.8V:

But the filter result of Vivado 2017.1 showed two flashes with 1.8V and 3.3V.

I wonder which one I should select. Is there any tutorial for programming SPI flash with Vivado?

 

Thanks a lot.

Please select mt25ql (low voltage which is 3.3V. And Second is mt25qu (U- Ultra Low voltage which is 1.8V )

 

If you select mt25qu, vivado issues an error message:
