Try running the xilsf_qspips_stm_polled_example.c This code should run on Windbond W25Q devices per the code header.

Hi, thanks for your quick responce!
The xilisf_qspips_stm_polled_example compiles without errors, however itfails when it verifing the readbuffer of the normal read.
How can we check if the write actually works because if we run it on our Tranz te0270 board the write apears to write correctly, at least iit does not fail.
Thanks and cheers!
@Xilinx why are there winbond examples if they do not work with winbond flash? Am I missing something?

I would advise stepping through the xilisf_qspips_stm_polled_example code to see where the issue is. Once you have that I can open up a CR to get that resolved.
For Zynq 7000 designs, the qspips are the proper examples. For the Zynq UltraScale+ the qspipsu are the correct examples, the other examples are for AXI QSPI.

I stepped trough the example. The condition in line 355 is met. The ReadBuffer array is empty. The write and read calls where executed with status 0.
