qspi flash sample in zephyr

[Abderrezak Mekkaoui]

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

Hi

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

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!

Hi

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

Hi Simon,

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

Thanks,
Matt
