But you can try the LUT in qspi demo first. If it works, then test in qspi_config_block. AN5244 is the application notes of QSPI. You can take a look.</P><P></P><P>Regards,</P><P>Jing</P></BODY></HTML> Wed, 19 Dec 2018 10:16:50 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/TWR-POS-K81-QSPI-is-not-working/m-p/781964#M47617 jingpan 2018-12-19T10:16:50Z
