When compiling NFC for nRF52840 with SDK 15.0.0, there are compiler errors.

David Fernandez

When building a project that compiles the hal_nfc_t2t.c, it errors for nRF52840, but works for nRF52832.

For the nRF52840, I get these errors:

Looking for some of the missing masks, I get that they are defined in nrf52_bitfields.h:

$ grep -nrEe 'NFCT_ERRORSTATUS_NFCFIELDTOOWEAK_Msk' ../nRF5_SDK_15.0.0_a53641a/components/
../nRF5_SDK_15.0.0_a53641a/components/nfc/t4t_lib/hal_t4t/hal_nfc_t4t.c:153:    #define NRF_NFCT_ERRORSTATUS_ALL (NFCT_ERRORSTATUS_NFCFIELDTOOWEAK_Msk   | \

$ grep -nrEe 'NFCT_ERRORSTATUS_NFCFIELDTOOWEAK_Msk' ../nRF5_SDK_15.0.0_a53641a/modules/
../nRF5_SDK_15.0.0_a53641a/modules/nrfx/mdk/nrf52_bitfields.h:4480:#define NFCT_ERRORSTATUS_NFCFIELDTOOWEAK_Msk (0x1UL << NFCT_ERRORSTATUS_NFCFIELDTOOWEAK_Pos) /*!< Bit mask of NFCFIELDTOOWEAK field. */

But that is not included for nRF52840 by ../nRF5_SDK_15.0.0_a53641a/modules/nrfx/mdk/nrf.h:

...
     78     #elif defined (NRF52840_XXAA)
     79         #include "nrf52840.h"
     80         #include "nrf52840_bitfields.h"
     81         #include "nrf51_to_nrf52840.h"
     82         #include "nrf52_to_nrf52840.h"
     83     #elif defined (NRF52832_XXAA) || defined (NRF52832_XXAB)
     84         #include "nrf52.h"
     85         #include "nrf52_bitfields.h"
     86         #include "nrf51_to_nrf52.h"
     87         #include "nrf52_name_change.h"
 ...

Is this a bug in the mdk for nRF52840, or am I missing something?

    what example are you trying to compile?

     By "This is just my project, but the compilation for the SDK file fails", I believe that you are creating a custom file, is that right?

    As the compiler says, you are missing a bunch of declarations. Are they included in your project? It is typically a missing file, or a define that is not set correctly, so that the declarations are skipped. E.g.:

    #ifdef NRF52840
#define A_BUNCH_OF_VARIABLES
#endif

    Can you try to add the define BOARD_PCA10056 to your preprocessor defines?

    I see that the NFCT_ERRORSTATUS_NFCFIELDTOOSTRONG_Msk (and the other defines that are not present) are only used if HAL_NFC_NRF52840_ENGINEERING_ABC_WORKAROUND is not defined. HAL_NFC_NRF52840_ENGINEERING_ABC_WORKAROUND is defined is BOARD_PCA10056 is defined. If you are not using the nRF52840DK, and hence don't have the define BOARD_PCA10056, you must then define HAL_NFC_NRF52840_ENGINEERING_ABC_WORKAROUND in your preprocessor defines.

    Hi Edvin,

    Yes, I am compiling a custom project, not an example. Although, given the command line, it should not matter, as it should be the same for any project that uses NFC in the nRF52840... unless I am missing something.

    The command line should tell you what I am using and should allow you to identify what is missing.

    I did my little investigation about what is missing after the first block, so that you can tell me why this happens.

    If you look at what I put after the compiler errors, you can see why those are missing. They are defined for nRF52832, but they appear not to be defined for nRF52840.

    OK, that seems to be the define that I am missing.

    If you are saying that that define is just done inside the #ifdef BOARD_PCA10056 clause for the boards.h, then it seems clear why I am missing it, as I was assuming that that define should not be in that file at all, but either in the Makefile instead.

    I thought that boards.h and custom_board.h only have GPIO define aliases to have the same firmware working across different pcb hardware versions.

    Anyway... I'll check all that now and retry.

    I wonder, why the grep did not find those in any other file though...
