Open nRF Connect SDK Project fails when importing project with board.c out of tree source file

[LucaF]

Hi,

I'm esperiencing this error when I try to import a project which has board folder inside project folder and board definition include board.c sourcefile (nrf52840dongle_nrf52840),

C:\Users\Luca\ncs\v1.9.1\toolchain\opt\bin\arm-none-eabi-gdb.exe: warning: Couldn't determine a path for the index cache directory.

I'm able to import whitout problems the project with out tree board difinition which do not require board.c sourcefile (nrf52840dk)_nrf52840.

I'm using windows 10 and Segger IDE and 1.9.1 nRF Connect SDK. My Documens folder is on disk D: whereas SDK is on disk C: standard installation folder.

I need to make changes to board.c file, but for this test I just copied the board definition folders in my project folder in boards/arm subdirectory, without modification.

Here the tree structure:

D:\Users\Luca\Documents\nRF52\Peripheral
 - src
 - CMakeList.txt
 ...
 
D:\Users\Luca\Documents\nRF52\Peripheral\boards\arm\nrf52840dongle_nrf52840
 - board.c
 - CMakeList.txt
 ...

I changed the project makelist file in accordance to Out Of Tree Board sample project, and it works when no board.c source file required.

Here the full log from the importer and project makefile:

Thank you very match for your help.

Hi Luca,

Did your project with board.c file work before you tried to import it?

Could you also describe the procedure that you used to make your project? Did you use any of our examples as the starting point?

Best regards,
Dejan

[LucaF]

Yes, it did.

Today, I checked the project on another PC running windows 10, but where folder project is in the same disk as the SDK and it worked too. I think that problem arises only when board.c is on another disk than SDK.

[dejans]

Hi,

Please use the same disk drive for both the NCS and your project.

Best regards,
Dejan

[LucaF]

I confirm that moving NCS to the same disk of my source project, it works.

Thanks
