Qspi flash sample project error

[jspiller]

Hello, I am trying to use the spi_flash sample project with a laird bl654 dvk. 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!

This is a onboard flash that supposedly should work from this post https://devzone.nordicsemi.com/f/nordic-q-a/64769/qspi-flash-sample-in-zephyr. I am using sdk 1.9.1.

Hi,

 

For the example to work, you must define a $(board).overlay and $(board).conf file in the boards catalog of the example.

In your case it would be boards/bl654_dvk.conf and boards/bl654_dvk.overlay.

You should follow the setup similar to how it is done for the nRF52840-DK, with QSPI being enabled:

https://github.com/nrfconnect/sdk-zephyr/blob/main/samples/drivers/spi_flash/boards/nrf52840dk_nrf52840.conf#L8

 

And the MX25R64 itself being defined in the board:

https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/nrf52840dk_nrf52840/nrf52840dk_nrf52840.dts#L209-L235

 

Kind regards,

Håkon

Hi,

Those are the steps I took to receive that message. Not sure how to proceed from there. I have also closed all the bridges required for the qspi flash.

Thanks,

Did you try this on a nRF52840-DK first to see if it worked there?

 

I see now that the bl654_dvk board defines this as a spi-nor device in the overlay, not a qspi device:

https://github.com/nrfconnect/sdk-zephyr/blob/main/boards/arm/bl654_dvk/bl654_dvk.dts#L135-L152

Try adding this to the top of your .overlay file:

/delete-node/ &mx25r6435f;

then setup your &qspi structure with the "MX25R64" labeled device in it.

 

If it still does not work, could you share your overlay and config files?

 

Kind regards,

Håkon

Thanks for the response,

I just tried putting that line in, but it throws "parse error: undefined node label 'mx25r6435f'" when I try to build. I tired adding the "@0" as well. Using "/delete-node/ &spi1;" is recognized but does not seem to solve the issue. In the device tree the node does show up however, I have tried manually disabling spi1 as well, but no luck. Here is my .conf and .overlay files.

I have not tried this on a nRF52840dk, does that board have a spi flash on it?

Sorry for that, it seems that this peripheral/node isn't required to delete.

This is the overlay and conf file that I placed in the board folder for the bl654_dvk:

bl654_dvk.conf

bl654_dvk.overlay

 

The pin-outs are edited to match the nRF52840-DK, as I do not have this module at-hand.

This ran as expected when flashed:
