SDK 2.3.0 - can't disable qspi in DT overlay file?

Hi guys,

I got both this case and the case you refer to.
I do not think the thing in the other case is a bug, which answers this case.

Right now I am typing an answer to the other case.
If you agree with me that it is not a bug after reading my upcoming answer there, we can close this case.

If not, we can have a look at if it is fixed in 2.4.0 or not.

Regards,
Sigurd Hellesvik

I use b0, mcuboot for my project.
I disabled qspi in the application overlay, but
I guess this problem was because b0 & mcuboot overlay files were not there.
If my guess is correct, this situation makes some sense.

Does the peripheral work only with status = okay in the device tree?
There is no config setting, include driver, initial in my project, but qspi works.
I don't understand this part.

Hi,

I also tried to reproduce it with peripheral_lbs example etc, but I could not.
Before disabling QSPI in overlay file, QSPI pins swinged and cs pin was high state.
However, all QSPI pins didn't swing and maintained low state after disabling QSPi in overlay file.
Previous case mentioned that only QSPI seemed not be controlling by overlay.
So, I tried this with overlay file settings the case owner shared, but I also could not reproduce it.
I could not reproduce all of things with nRF5340-DK.
Maybe, it's related to the custom board settings.
It will be good to reproduce on nRF5340-DK.

Which example are you building, and what board are you targeting?

I just tried to build the peripheral_uart sample for the nrf5340dk_nrf5340_cpuapp board in NCS v2.4.0, and I can see that the status of the qspi peripheral is changed to "disabled" in the build\zephyr\zephyr.dts file after I add code to disable it in the app.overlay file.

As a general comment it is recommended to develop your own board files if you are making a custom board, rather than using overlays, but if there is a bug in the SDK related to this then it should be fixed obviously.

Best regards
