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

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?

[Farhan95]

I also did the same with my hello world sample and getting the same result. 

[Sigurd Hellesvik]

Could you zip that and upload it here so I can try the exact same?

[Farhan95]

8765.littlefs.zip Hi, I have uploaded the zip file. I am using the little fs sample code and modify the overlay file and prj file for my nrf52832. 

I am getting the waring every time. 

[Sigurd Hellesvik]

It works for me as you can see below.
Have you changed anything in the SDK?

it also works for me but got the warning. and yellow line under CONFIG_SPI_NOR=y 

[Sigurd Hellesvik]

The warning should also be present in your build log, right?
