SDK15 NRFX error numbering

[keith v]

Maybe there's a secret I'm missing but this looks like a development / debug flag that got left in.

I'm porting an app from SDK11 to SDK15, when I call app_button_init() it calls nrf_drv_gpiote_init() which is mapped to nrfx_gpiote_init()

Everything works and nrfx_gpiote_init() returns NRFX_SUCCESS.

But NRFX_SUCCESS is not zero.

So nrf_drv_gpiote_init() returns NRFX_SUCCESS which is then checked by VERIFY_SUCCESS(err_code), and promptly blows up and lands in the app error handler.

Since this is happening in the SDK code it's a problem

From app_button.c

if (!nrf_drv_gpiote_is_init())
{
    err_code = nrf_drv_gpiote_init();
    VERIFY_SUCCESS(err_code);
}

from nrfx_errors.h

#define NRFX_ERROR_BASE_NUM         0x0BAD0000
#define NRFX_ERROR_DRIVERS_BASE_NUM (NRFX_ERROR_BASE_NUM + 0x10000)

/** @brief Enumerated type for error codes. */
typedef enum {
    NRFX_SUCCESS                    = (NRFX_ERROR_BASE_NUM + 0),  ///< Operation performed successfully.
    NRFX_ERROR_INTERNAL             = (NRFX_ERROR_BASE_NUM + 1),  ///< Internal error.
    ...

So sorry, I should have been clearer. I was refering to the nrfx_glue.h located at "nRF5_SDK_15.0.0_a53641a/integration/nrfx" in the nRF5 SDK. It is based on the template from nrfx, but with changes required to use it with the nRF5 SDK. This section here is what you are missing:

#include <sdk_errors.h>
/**
 * @brief When set to a non-zero value, this macro specifies that the
 *        @ref nrfx_error_codes and the @ref ret_code_t type itself are defined
 *        in a customized way and the default definitions from @c <nrfx_error.h>
 *        should not be used.
 */
#define NRFX_CUSTOM_ERROR_CODES 1

typedef ret_code_t nrfx_err_t;

#define NRFX_SUCCESS                    NRF_SUCCESS
#define NRFX_ERROR_INTERNAL             NRF_ERROR_INTERNAL
#define NRFX_ERROR_NO_MEM               NRF_ERROR_NO_MEM
#define NRFX_ERROR_NOT_SUPPORTED        NRF_ERROR_NOT_SUPPORTED
#define NRFX_ERROR_INVALID_PARAM        NRF_ERROR_INVALID_PARAM
#define NRFX_ERROR_INVALID_STATE        NRF_ERROR_INVALID_STATE
#define NRFX_ERROR_INVALID_LENGTH       NRF_ERROR_INVALID_LENGTH
#define NRFX_ERROR_TIMEOUT              NRF_ERROR_TIMEOUT
#define NRFX_ERROR_FORBIDDEN            NRF_ERROR_FORBIDDEN
#define NRFX_ERROR_NULL                 NRF_ERROR_NULL
#define NRFX_ERROR_INVALID_ADDR         NRF_ERROR_INVALID_ADDR
#define NRFX_ERROR_BUSY                 NRF_ERROR_BUSY
#define NRFX_ERROR_ALREADY_INITIALIZED  NRF_ERROR_MODULE_ALREADY_INITIALIZED

#define NRFX_ERROR_DRV_TWI_ERR_DNACK    NRF_ERROR_DRV_TWI_ERR_DNACK

For convenience, here is the file: nrfx_glue.h
