Hello,
I'm developing a BLE application under nRF51422 based on SDK12.2 using softdevice S130.
Now, I'm porting the application from Keil to IAR 8.11.
There is no compilation I could download the generated binary file to the nRF51 but when debugging,
I see that the software maintaining blocked under the function nrf_delay_us(see the picture below).

Knowing that all of NRF51, NRF52840_XXAA, and NRF52832 symbols are not defined, I want to know the cause of this issue and how to fix it.
Best Regards,
Mehdi.
