Symbol SWI2_EGU2_IRQHandler multiply defined

[msquizzato]

Hello,
I updated the SDK and related SoftDevice of a project based on nRF52832_xxAA

from:
14.2.0 nRF5 SDK - 5.0.0 SoftDevice S132 (compiled  works with #define NRF_SDH_DISPATCH_MODEL 0)

to:
16.0.0 nRF5 SDK - 7.0.1 SoftDevice S132  (www.nordicsemi.com/.../Download nRF5SDK160098a08e2.zip)

after compilation the linker gives me the following error:

Linking ...
. \ _ build \ app_nrf52832_xxaa_s132.axf: Error: L6200E: Symbol SWI2_EGU2_IRQHandler multiply defined (by nrf_sdh_freertos.o and nrf_sdh.o).

how can you solve it?

I have found several blogs that talk about the same problem but have not been helpful anyway
Thank you

Did you try just removing nrf_sdh.c from the Makefile/project/solution?

but in the example
SDK \ examples \ ble_peripheral \ ble_app_hrs_freertos
there are both (nrf_sdh.c nrf_sdh_freertos.c) and it works



if I eliminate nrf_sdh.c other numerous errors are generated, as in my project

Hi,

nrf_sdh_freertos.c implementation is meant to be used in 'NRF_SDH_DISPATCH_MODEL_POLLING' mode. I just verified that the example in sdk 14.2.0 will produce the same error if you change it from the default NRF_SDH_DISPATCH_MODEL_POLLING setting to NRF_SDH_DISPATCH_MODEL_INTERRUPT.

you are right
#define NRF_SDH_DISPATCH_MODEL 2
it is necessary
thank you
