qspi flash sample in zephyr

Abderrezak Mekkaoui over 3 years ago

Dear All,

I am looking for sample code to use an external QSPI flash (MACRONIX MX25R6435FZAIL0). The code is run an nRF52840 based custom board.

Your help is appreciated.

Thanks

Simonr, isn't the "spi_flash" example (in "/ncs/zephyr/samples/drivers/spi_flash") an example of the the nRF52840-DK using the MX25R624 with QSPI?

Additionally, I have a related question, from the following https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fqspi.html, it mentions that the QSPI can be used for “Single/dual/quad SPI input/output”. In the "spi_flash" example quad spi is used. Do you know how I could go about getting dual-spi to work within Zephyr for the MX25R64?
