I use lauterbach to dump data in AHB Qspi region, and found the data always floating change.
The problem happened in Qspi0 port A, but is stable in Qspi1 port B.
I have upload a video to show that, what might be the problem?
That's hard to say, but this way usually incorrect setting manifest same way as reading of Hi-Z pins i.e. what you see on attached video. Also incorrect frequency or timing setup may exhibit this way.
