How to Access to NOR FLASH(25V1635F) of EMW3166

Hi.
I want to connect to NOR FLASH(25V1635F) ,included EMW3166 of AZ3166 , by QSPI .
But, MTB_MXCHIP_EMW3166 of Mbed OS doesn’t support QSPI.
Please teach me how to connect it using QSPI Library of Mbed OS.

Hi Shundai,

as support for this board has been dropped for Mbed OS 6 it is unlikely that QSPI will be added. However,
you may well be able to add the support for your own use, though this would have to be based on the 5.15 code base. This may help:
