error app: Fatal error ?

[RixtronixLAB]

Dear Members,

How can I find the cause of

<error> app: Fatal error ?

I can't see an error code ?

Is it possible hardware error because voltage surge ? Can capacitor rectify it ?

Thanks

Hi,

I can't see an error code ?

You will get more information (file name, line number and error code) by testing with a debug build. If you use a Segger embedded studio project from the SDK, simply select "Debug" from the build configurations dropdown menu. If using something else, define "DEBUG" and "DEBUG_NRF".

Is it possible hardware error because voltage surge ? Can capacitor rectify it ?

We need to know what the error code was and from where it was returned before we can consider what caused it and how it can be fixed.

I get a clue just now, when the board lost connection with the sensor, ANT HRM sensor, it's giving me

"error app: Fatal error"

If I used Keil, how can set "Debug" build ?

[Einar Thorsrud]

With Keil, go to Project -> Options for Target ...., and then select the C/C++ tab. There add "DEBUG" and "DEBUG_NRF" to the preprocessor define list as shown here:

If you want to debug (break in code, inspect with a debugger etc.) it makes sense to also set the optimization level to 0. That is not related to logging, though.

Thanks Einar, I'm compiling and uploading now, I'll keep posted
