Hello,
I also had a problem with the demo. It was stuck in the error trap infinite loop. Have you been able to solve this problem Wang?
Thanks.
Hello,
I would like to recommend to follow AN12193 - Using S32K148 QuadSPI Module
https://www.nxp.com/docs/en/application-note/AN12193.pdf
AN12193SW:

Also, have you changed the default resistor configuration to use QSPI?
Please, refer to the chapter USING ETHERNET AND QSPI in the QSG:
https://www.nxp.com/docs/en/quick-reference-guide/S32K148EVB-QSG.pdf
I hope it helps.
Best regards,
Diana
