Can't run Blinky on NRF9160-DK using nrf_connect toolchain and Zephyr

[Hash5422]

Hello, 

I've been trying to run both Blinky & Hello_WORLD examples given with NCS 1.6.1 on an NRF9160-DK but I don't see any output. I was able to build & run successfully using SEGGER and WEST commands from the command line, but on debugging, it seems to be getting a hard_fault error before hitting main(). Am I missing something here?

So I am unable to run it even without debugging, I see that Segger flashed it correctly, but the LEDs don't blink on the board. Is there a startup sequence that I should be following for firmware download? Does it require a bootloader update or something, I'm just trying to understand why the example project wouldn't hit main().
