Custom board configuration

[RMV]

I am bringing up a custom board based on the PCA10040.

As the first step, I simply copied (no changes) the file pca10040.h and named it as "my_custom.h".
I then defined the symbol BOARD_CUSTOM using the command line -DBOARD_CUSTOM=1
I can see that the file "boards.h" properly identifies and uses the newly copied  header file "my_custom.h"

But then when I build this configuration, the linker complains about undefined references:

C:/Z_PROJECTS/SVN_PROJECTS/DoorSentry/branch/NRF5_2832/nrf5_sdk/components/libraries/button/app_button.c:82: undefined reference to `nrfx_gpiote_in_is_set'

collect2.exe: error: ld returned 1 exit status

What I don't quite understand is that the build is successful if I revert back to using "pca10040.h".
And I simply copied the same board file over to a different name!

Anybody care to help me get to the bottom of this? I am using SDK v15.3.0

Hi,

Even though you copied the same board file, did you copied all the dependency files? I can see that you have made a different folder even though you're using SDK 15.3.0

app_button.c file exist in component/libraries/button folder, check this folder in project path. Further, which IDE you're using? You need to mention relative path of missing dependency files in project options. Sometime, missing c files need to be manually added in project explorer in IDE.

Thanks,

Hi pdpro,

Thanks for the feedback. The folder name is not critical -- I just chose to rename it.

I am able to finally get the build to complete after I include the sources for the nrfx_* drivers in the project.
What was tripping me up was the fact that without this folder, the standard PCA10040 version was building.
My best guess is that the build system somehow pulled in the "legacy" layer of the GPIOTE and was silently generating invalid code -- which I never tested in any case.

I will mark this as verified.

Thanks everybody.

Glad that you're able to figure it out.

Thanks,
