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,

Jacob

No, you're setting the physical pin number, while you should set the GPIO number.

Could you please try the suggestion that I previously posted?

Are you certain that your DTS setup is correct as per the bl654 schematic?

sck-pin should be 19, csn should be 17, and io-pins should be 20-23, atleast how I read their schematic.

Kind regards,

Håkon

I see, thank you. However the same problem still arises with either pin configuration. Here is my full project:

Hi,

 

Looks like a number snuck into the csn definition:

	csn-pins = <117>;

It seems that the bl654 board has copied the same pinout as the nRF52840 DK, so you can just copy the definitions from here:

https://github.com/zephyrproject-rtos/zephyr/blob/zephyr-v2.7.1/boards/arm/nrf52840dk_nrf52840/nrf52840dk_nrf52840.dts#L209-L235

 

Kind regards,

Håkon

Hi,

Yes, sorry about that. It must've been a typo from when I changed it back regarding your last message. However, using the pin configuration from the github link you sent is the starting point for me from when I started the post and still does not work.

Hi,

 

I think you should contact the manufacturer of the EVK that you're using and ask if they have proper configuration for usage of qspi flash with this board.

As previously mentioned, it looks like it is the same routing as we have on our nRF52840-DK, and I ran the example with qspi, configured for the board bl654_dvk, but running on the nRF52840-DK, with no issues on my end.

 

Kind regards,

Håkon
