CONFIG_SPI_NOR was assigned the value y, but got the value n.

[Farhan95]

Hello,

I am trying to implement littlefs in my external flash memory. I am using nrf52832 and try to implement the littlefs sample code. 

When I am trying to enable Config_spi_nor then I found CONFIG_SPI_NOR was assigned the value y, but got the value n. Could you please help me how I can enable this configuration? 

I am also attaching my overlay file and prj file. Please have a look. 

 

Thank you.

Best regards

Hi,

Which board are you using?

Does this board have an external flash on it?

Is the SPI DTS node you use enabled (status = "okay")?

Regards,
Sigurd Hellesvik

[Farhan95]

Hi Sigurd,

I am using nrf52832 board. I connect one external flash (IS25LP128) and try to implement littlefs on it. 

In my prj.config file, I enabled 

CONFIG_SPI=y

Is there any other way to enable the SPI DTS node? 

Thank you 

Regards

Farhan

[Sigurd Hellesvik]

In zephyr.dts, the &spiX node must have

status = "okay";

for it to be enabled in DTS. Check out build/zephyr/zephyr.dts to see how the full DTS for you build looks. This is both to check what the SPI is set to, and to see examples of how other nodes do it.

[Farhan95]

The status is ok in zephyr.dts. 

still the same error I am getting.

[Sigurd Hellesvik]

That is spi1, but in your below overlay, it looks like your configuration is connected to spi2?

[Farhan95]

SPI2 status is also okay. 

Moreover I try SPI1 in the overlay as well. Still get the same issue.

[Sigurd Hellesvik]

Looks like maybe the overlay is not included in the build?

Try to make an obvious error in the overlay file and see if that crashes the build?

[Farhan95]

I make a obvious error in the overlay. 

Change the compatible "nordic,nrf-spi" to 'jedec,spi-nor' . 

It crashes the build. I am attaching the error massage here.

[Sigurd Hellesvik]

I tried on my end.

To build the hello world sample with the overlay and prj.conf you supplied earlier in this ticket. Building for nrf52dk_nrf52832.

And it builds without error on my side.
Do you see the same if you do this with the hello world sample?
