QuadSPI IP Core Driver xspi.c v4.5 Issue

Hello *!

Did anyone else observed an issue using xspi.c in version 4.5 when writing/reading SPI flash chips?

I used Vitis 2019.2 and the system uses a Microblaze and the Quad SPI Core 3.2 for the flash routines.
I'm using the interrupt handler based flow.

I couldnt write/read to/from a MT25QU128 after upgrading the system including a driver version upgrade from 4.4 to 4.5.
After backporting the changes in the xspi.c everything is working again.

* 4.5 akm 05/29/19 Removed master inhibit dependency while writing DTR in between multiple transfers.

Basically i removed/backported all the inhibit dependency changes introduced by akm.

Did anyone else observed that? Do i need to change something in die Initialisation phase when updating vom 4.4 to 4.5?

Regards,

Dirk
