Hello,

[quote user=""]

I also tried adding the following property to the node:

quad-enable-requirements = "S2B1v1";

But it didn't work.

Based on the datasheet for this part I think it should be S1B1 but this is currently not supported in the driver here: https://github.com/nrfconnect/sdk-zephyr/blob/f7859899ec7dbb21e0580eef25b229bda727f04a/drivers/flash/nrf_qspi_nor.c#L667. Can you try to patch the driver and see if it works if you set sr_num = 1;
and qe_mask = BIT(1)?

Best regards,

Vidar
