Cannot program QSPI memory through ASMI Parallel II IP

Hello, We have a design that connects Avalon-MM Cyclone V Hard IP for PCIe Intel FPGA IP to ASMI Parallel II IP. The Cyclone V is connected to a QSPI serial Flash memory MT25QL512ABB8ESF (512Mb) ...

Hi,

We have a FIX!

We replaced the ASMI II IP with Intel FPGA Generic QUAD SPI Controller II Core, which also supports our specific Flash device, and succeeded to write to the Flash memory.

Thanks

Hi Wincent,

We didn't solve the problem yet.
What I meant is that I am not sure that we need to include the Serial Flash Loader IP, since we already able to perform some Flash operations by just using the ASMI II IP, like reading from it, changing its status registers, and even erasing it (what means that the write enable bit was enabled), etc. But direct data write is not working for us. So, the QSPI pins must be toggled by the ASMI II IP during the operations that do work. I assume that the SFL is already embedded in the ASMI II IP.
So, my question was if you still think that we need to include the SFL in our design?

Thank you
Avi
