Error next to zephyr/kernel.h: "In included file: "_DSP_PRESENT and CONFIG_ARMV8_M_DSP are not set to the same value"

[roaibrain]

I am using ncs sdk, my projects are under ~/zephyr-workspace. This is from an example project - blinkypwm. The clangd compiler shows the following erro: In included file: "_DSP_PRESENT and CONFIG_ARMV8_M_DSP are not set to the same value. I am on an ubuntu linux system and developing on a text editor (nvim). The ncs sdk is in ~/ncs. I have installed the zephyr toolchain and have initialized a west workspace.

I understand that this is a configuration mismatch in the Zephyr RTOS build system. The error indicates that there's an inconsistency between the settings in my build configuration, for:

• _DSP_PRESENT: Hardware capability flag
• CONFIG_ARMV8_M_DSP: Software configuration flag

Both of these are not in my proj.conf nor have I been able to find these exact one in kconfig using the gui interface menuconfig

Hence, I thought I could resolve this can resolve this by, adding the line to prj.conf

But then I get the following error on building the project. I tried searching for a similar option in kconfig using the gui interface, was unsuccessful.

If I remove the bool variable from proj.conf, the error is shown in the editor. Tho, the project builds and flashes into the nrf52832dk and functions are expected.
I really want to solve this error although for now it does not seem to cause any issues, unsure of its effects in future projects.

Any help would be appreciated.

Hi,

 

Based on the emitted zephyr version of v4.0.99, it looks like you are running upstream zephyr?

ncs-zephyr is currently at v3.7.99, even in the main branch.

 

In general, we do not recommend using main, but rather a tagged version.

 

Can you confirm what tag/hash that you're using?

 

Kind regards,

Håkon

Zephyr v4.0.0-2778 with commit hash 1b70bfa14e

So yes, I am using an upstream zephyr. I see, that it is recommended to use ncs-zephyr instead. 

I will set up NCS v2.5.0, which uses ncs-zephyr v3.3.99, and will let you know if things work out.

Now I get this build error:

I used west build -b nrf52dk_nrf52832, for the upstream zephyr this board was nrf52dk/nrf52832

I have ncs at ~/ncs and the project at ~/zephyr-workspace/blinkypwm/
ZEPHYR BASE points to ~/ncs/zephyr/

I don't understand the error : Invalid BOARD

hmm, this actually solved itself by adding --pristine to the build command, why?

Also, no longer see the error in my code
