Hi Simon,

I just wanted to update this thread that with current versions of the Nordic Zephyr SDK the dual QSPI works.

Thanks,
Matt

As this case is almost 1 year old, could you please create a ticket of your own instead, as this is slightly off-topic to this specific ticket.

Best regards,

Simon

Hello, I am also trying to use the spi_flash sample project with a custom board with this same flash chip on it, the laird bl654 dvk to be specific. When I run the project however, dev->state->init_res = 19 and will not run for me. It recognizes the device and if I manually set the error code to 0 the project runs correctly. Any idea why this is occurring. The output is

JEDEC QSPI-NOR SPI flash testing
==========================
SPI flash driver MX25R64 was not found!

No, we do not have any particular dual SPI examples, but it should be able to modify the QSPI example to run in dual SPI mode. I would suggest that you create a separate DevZone ticket if you need any details on how to do that though.

Best regards,

Simon

Simonr, is there any new information regarding getting dual-spi to work within Zephyr for the MX25R64?

Hi Matt

Yes, this is correct. I'm not entirely sure, but this might not have been part of the Zephyr version available in August, but I could be wrong of course and I may simply have missed it. Either way,the SPI_Flash sample project should indeed work for using the MX25R624 with QSPI. Thank you for the update!

I'm sorry, it doesn't seem like we've got any dual-SPI examples in particular. If you have any particular questions/issues with setting this up, I suggest creating a separate ticket where you describe in detail what exactly you need help with in regards of implementing dual SPI and we'll do our best to assist you.

Best regards,

Simon

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?

I'm sorry, but we don't have any QSPI sample projects in NCS as of yet, and I was not able to find a sample in Zephyr either. You can check out our QSPi driver located here, but a full sample is still in the works.

Alternatively, you can check out the QSPI example in our nRF5 SDK and use that as a base for a template of sorts in a Zephyr project, just to get a feel for how initialization is done and so on.

Best regards,

Simon
