identifier "APP_IRQ_PRIORITY_MID" is undefined using spi_5W_master and softdevice

[SG1]

I am trying to update an older application use the spi_5W_master and receive the error: (SDK11, using S210 softdevice)

:RTE\nRF_Drivers\nRF51422_xxAC\spi_5W_master.c(346): error:  #20: identifier "APP_IRQ_PRIORITY_MID" is undefined

I've traced it to app_util_platform.h  where the following is a part of the file definitions:

#ifndef SOFTDEVICE_PRESENT
    APP_IRQ_PRIORITY_HIGHEST = 0,
#endif
    APP_IRQ_PRIORITY_HIGH    = 1,
#ifndef SOFTDEVICE_PRESENT
    APP_IRQ_PRIORITY_MID     = 2,
#endif
    APP_IRQ_PRIORITY_LOW     = 3
} app_irq_priority_t;

If the softdevice is defined (which it is) APP_IRQ_PRIORITY_MID is not defined.

in spi_5W_master.c the following is present :

    NVIC_SetPriority(p_spi_instance->irq_type, APP_IRQ_PRIORITY_MID);

In the previous spi master, it was set to low if a softdevice was present.

Hi,

What SDK version is that app_util_platform.h file from? This is the default from SDK 11:

/**@brief The interrupt priorities available to the application while the SoftDevice is active. */
typedef enum
{
#ifdef SOFTDEVICE_PRESENT
    APP_IRQ_PRIORITY_HIGHEST = _PRIO_SD_HIGH,
#else
    APP_IRQ_PRIORITY_HIGHEST = _PRIO_APP_HIGH,
#endif
    APP_IRQ_PRIORITY_HIGH    = _PRIO_APP_HIGH,
#ifndef SOFTDEVICE_PRESENT
    APP_IRQ_PRIORITY_MID     = _PRIO_SD_LOW,
#else
    APP_IRQ_PRIORITY_MID     = _PRIO_APP_MID,
#endif
    APP_IRQ_PRIORITY_LOW     = _PRIO_APP_LOW,
    APP_IRQ_PRIORITY_LOWEST  = _PRIO_APP_LOWEST,
    APP_IRQ_PRIORITY_THREAD  = _PRIO_THREAD     /**< "Interrupt level" when running in Thread Mode. */
} app_irq_priority_t;

Best regards,
Jørgen

Hi,

The board support shows 11.0.0-2.alpha, NRF drivers and NRF libraries are all 4.0.0-2.alpha.

Thank you for responding,

I do recommmend that you upgrade the SDK version to the final version of SDK 11 (can be downloaded here), or better, upgrade to the latest SDK with support for nRF51 series, SDK 12.3 (can be downloaded here). From your last comment I suspect that you are using CMSIS packs version of our SDK. Note that we deprecated support for CMSIS packs a while ago, and you are not able to get the latest releases this way.
