"twi + softdevice" not working !!! makefile build fails

Brook Gebremedhin

hello,

my makefile use to work before i add the twi nrf_drv_twi.c file and included the directory INC_PATHS += -I$(abspath ../../../../../../components/drivers_nrf/nrf_soc_nosd)

i get the error below when building at app_util_platform.c:

 app_util_platform.c: In function 'app_util_critical_region_enter':
/Users/brookgebremedhin/nordicSDK11/components/libraries/util/app_util_platform.c:36:3: error: implicit declaration of function 'sd_nvic_critical_region_enter' [-Werror=implicit-function-declaration]
   (void)sd_nvic_critical_region_enter(p_nested);
   ^
/Users/brookgebremedhin/nordicSDK11/components/libraries/util/app_util_platform.c: In function 'app_util_critical_region_exit':
/Users/brookgebremedhin/nordicSDK11/components/libraries/util/app_util_platform.c:49:3: error: implicit declaration of function 'sd_nvic_critical_region_exit' [-Werror=implicit-function-declaration]

if i tell the makefile that i am not using the soft device then it can build. cam anyone show me a working makefile that uses twi and soft device together ?

my makefile is attached below

thanks

    Do not add the directory ../../../../../../components/drivers_nrf/nrf_soc_nosd to your include path if you are using the SoftDevice. That directory is only for projects that don't use the SoftDevice.

    Instead, add the directory ../../../../../../components/softdevice/s130/headers to your include path.

    The project needs to have the file nrf_drv_config.h added, and then edited to enable the TWI interface. Either set TWI0_ENABLED to 1 or TWI1_ENABLED to 1, depending on which of the two TWI peripherals you want to use. And set TWI0_USE_EASY_DMA or TWI1_USE_EASY_DMA to 0, since Easy DMA is only supported for nRF52.

    One of my habits is to search the Nordic SDK for certain file names when they appear in my compiler error messages. This has taught me things that I have trouble finding in the SDK documentation or tutorials.

    I'm using the PCA 10036 board and SDK 0.9.2. There are THREE versions of the file nrf_error.h in SDK 0.9.2. They are located in the following directories:

    components/softdevice/s132/headers
components/softdevice/s212/headers
components/drivers_nrf/nrf_soc_nosd

    Eventually I figured out that "nosd" stands for "NO SoftDevice." Hope that helps someone else.
