Define BOARD_CUSTOM not working in SDK12 with GCC

[Chris H.]

I can't seem to add custom pin definitions to my own board in SDK12. I use the BOARD_CUSTOM define and copied my PCA10040 header file to one call custom_board.h and my pin assignments do not change. The only warnings I get are from bad paths to the config folder which is new since moving to SDK12.

Thank you for all your help Roger! Your work around helped me. BUT I just tested "#define BOARD_CUSTOM" in Keil 5.2 and it doesn't work. Problems like this are very frustrating to engineers like myself that assume things work as documented....

I don't use Keil, but I do have the demo installed, and if you look in the project options under C/C++ and also under ASM, you can define Preprocessor Symbols

I think that would be where you'd need to define BOARD_CUSTOM

I don't have IAR, but if you look in blinky_pca10040.ewp in the iar folder you'll see

<option>
  <name>CCDefines</name>          <state>NRF52832</state>          <state>BOARD_PCA10040</state>

etc

and the same in

ADefines

So.. I agree the documentation is confusing, as they use the term #define BOARD_CUSTOM when in fact they just mean that BOARD_CUSTOM must be defined.

I think the only way to do this in practice is via a compiler (preprocessor) directive (or the equivalent project settings or options)

Hi Chris,

I agree to your discussion that the documentation should not have mentioned #define as different compilers override these defines in the file in different ways given in the build settings. I will ask the team to remove #define and say that "you should make sure that only BOARD_CUSTOM" is defined in your build target OR your header file and no conflicting flags are set either in build target or in the header files". Does this sound ok?

[Chris H.]

Yes Aryan that would be good. Thank you.

I have raised internal ticket reference NRFFOETT-1477. As this is documentation error, i would not like to add this to known SDK12 issues as it mostly concentrates on software anomalies.
