nrf52832 undefined reference to `nrfx_comp_init'

RE: nrf52832 undefined reference to `nrfx_comp_init'

This is a known issue, where in some example projects sdk_config.h it's resolved and some not.

This is why I maintain my own base sdk_config.h version (per SoftDevice) which I have

#ifdef NRF_LEGACY_LAYER_ENABLED

...

#endif // NRF_LEGACY_LAYER_ENABLED

Surrounding all legacy nrf_drv #define (to allow easier merge of newer sdk_config.h versions)

Hahaha you got me there! :-)

This was it - when I commented out those three lines it worked as expected.

No need to do the -DCOMP_ENABLED=1 in the Makefile.

This means you might have the nrf_drv_comp (obsolete) COMP_ENABLED present in your sdk_config.h (which overrides NRFX_COMP_ENABLED)

Look at your sdk_config.h for this

//==========================================================
// <e> COMP_ENABLED - nrf_drv_comp - COMP peripheral driver - legacy layer
//==========================================================
#ifndef COMP_ENABLED
#define COMP_ENABLED 0
#endif

And comment it out.

Hi, I've managed to solve this issue by myself.

In my Makefile I've added -DCOMP_ENABLED=1 in the CFLAGS section.

The problem has something to do with

/nRF5_SDK_17.0.0_9d13099/integration/nrfx/legacy/apply_old_config.h

but I don't have time to investigate.

I hope this helps!

Regards,

I've added some garbage in the nrfx_comp.c and the compiler didn't see it. This means that for some reason NRFX_COMP_ENABLED is 0.

I tried, it still fails.

I've opened the config/sdk_config.h with my default text editor and I confirm on 100% that NRFX_COMP_ENABLED is set to 1.

I'm using Eclipse, and when I open nrfx_comp.c the entire file is gray, as if NRFX_COMP_ENABLED is not 1.

When I open nrfx.h I see this:

#include <nrfx_config.h>
#include <drivers/nrfx_common.h>
#include <nrfx_glue.h>
#include <drivers/nrfx_errors.h>

and sdk_config.h is nowhere included ... That's why I assumed that maybe my <nrfx_config.h> is the wrong one ...

Are you sure the sdk_config.h you edited to is the correct one being referenced in the project during the build?

As if NRFX_COMP_ENABLED is not enabled, nrfx_comp_init won't be build and linked...

Try and move the "../config \" to the top of the top of the INC_FOLDERS section

And make sure ../config/sdk_config.h has NRFX_COMP_ENABLED set to 1

In the Makefile, `SDK_ROOT` is defined as a relative path

SDK_ROOT := ../../../../../..

Can you share your Makefile (Insert->Code) and your folder structure?

RE: nrf52832 undefined reference to `nrfx_comp_init'

L.B. — Fri, 17 Jul 2020 10:09:51 GMT

I believe my project points to the wrong nrfx_config.h file ... but I cannot understand how does my Makefile do the connection to the correct:

nRF5_SDK_17.0.0_9d13099/modules/nrfx/templates/nRF52832/nrfx_config.h

RE: nrf52832 undefined reference to `nrfx_comp_init'

L.B. — Fri, 17 Jul 2020 10:07:37 GMT

Yes, in my Makefile I've added:

$(SDK_ROOT)/modules/nrfx/drivers/src/nrfx_comp.c \

in the "SRC_FILES += \" section.

RE: nrf52832 undefined reference to `nrfx_comp_init'

Shahar — Fri, 17 Jul 2020 09:57:57 GMT

Did you also added nrfx_comp.c to the project?

From your SDK folder, add to the project a reference to the following: modules/nrfx/drivers/src/nrfx_comp.c
