QSPI Flash Zephyr Driver

[RPDben]

Hi,

I have been looking around the forum and have found conflicting information regarding the existence of a QSPI flash driver and example for the nRF53 on Zephyr. Is this something that exists for either prototype or production release?

Thanks!

Hi

Please check out the drivers/files listed below in the NCS for QSPI flash drivers. As of nRFConnect SDK v1.4.99 (the as of now latest release) the QSPI driver was updated to include support for the nRF53 series SoC. We have not yet released any example projects for the nRF5340 DK using the QSPI driver though, so you'll have to implement the driver in an example yourself. 

ncs\modules\hal\nordic\nrfx\hal\nrf_qspi.h
ncs\modules\hal\nordic\nrfx\drivers\src\nrfx_qspi.c
ncs\modules\hal\nordic\nrfx\drivers\include\nrfx_qspi.h

Best regards,

Simon

Hi Simon,

Thanks for this, we will check this out and start working on an implementation.

Thanks!

Hi Simonr

May I know is there a QSPI sample code that was released from Nordic to control external flash on nRF5340-DK in NCS v1.5.1??

Thanks.
