assert() stopped working. Generates 'undefined symbol' error

[eyalasko]

Hi,

I'm basing my project on ble_hrs_freertos example project (nRF52832, SDK14.2, PCA10040)

When calling assert(condition) in the original example project, it works as expected.

When calling assert(condition) in my project I get "Error: L6218E: Undefined symbol __aeabi_assert (referred from main.o)." linker error message.

(The reason for using assert() rather than app_error_handler()-like functions, is that substantial part of the code should run on other platforms. These platforms support assert() but not the nordic-specific forms)

I've changed none of my project's linker settings (to the best of my knowledge) and when including <assert.h> I see extern reference to __aeabi_assert (see screen cap).

Where else can I look?

Any advice will be highly appreciated.

Thanks

Hello, 

I am not sure why this is not working. The assert.h file is something that you have written, right?

I see that there is a lot of #if defines. Are you certain that this declaration is included with the current defines that you have in the project?

 

Best regards,

Edvin

Hi Edvin, 

Thanks for your response.

assert.h is provided by Nordic SDK.

The #ifdef statements are included as their font is black rather than gray (when not included)

Hello,

I see that there is an assert.h in the SDK, but it does not look like the one you provided above. Do you have the declaration for __aeabi_assert somewhere in your project?

 

BR,

Hi Edvin, 

I figured out what was wrong:

instead of

#include <assert.h> and using assert()

Use

#include <nrf_assert.h> and use ASSERT() macro

Thanks for your support
