    Hi,

    Did you switch your jumpers to QSPI boot?

    Hello Elynum,

    Did you verify it worked properly over JTAG first? Did you create a FSBL? What exactly are you trying to program into the QSPI?

    Hhello elynum,

    Create a Hello World Application and try to program that into the QSPI. If you are unable you may be following incorrect steps to program the QSPI. What Vivado/SDK Version are you using? I can refer you to a suitable reference design that shows the steps.

    Vivado 2017.1.  I didn't think I would have to use SDK to program flash shouldn't I be able just to do it with vivado.  What I don't understand is, it says program succeeded.

    Hello elynum,

    I was assuming you were writing an application in C and not strictly using Verilog/VHDL. Yes you can prgoram straight from Vivado. Can you add an ILA core into your design and use the HW manage to watch the logic levels you are setting. Doing this you can compare the difference between having the image in the QSPI and the JTAG boot options.
