The circular dependency is still a problem, whether the softdevice is programmed or not. This seems to be because MAKECMDGOALS is not defined. I had to change it to flash: nrf52832_xxaa_s1xx_iot to make it work.

Great! It works now. Thank you very much!

But I still have this warning with "Circular flash"

In order for IoT applications to function you have to flash the SoC with the SoftDevice before you flash it with your application. The IoT SoftDevice is part of the nRF51-IoT-SDK-zip under Nordic\nrf51\components\softdevice\s1xx_iot. Flash the s1xx-iot-prototype2_softdevice.hex using for example nRFgo Studio or nrfjprog.
