When I run the UART app nRF5_SDK_12.3.0_d7731ad\examples\peripheral\uart in debug mode, the disassembly window opens, and I seem to get stuck on the first instruction. Step over doesn't step past the first instruction. Why is that? Thank you.

Here are the instructions I've following for setting the J-link debugger settings

I've tried flashing the soft device before flashing the app, but the flash fails in that case. The app only flashes if I erase the chip first indicating the soft device is flashed with the app (right?).

I think the problem is that you had run a project need softdevice.

And you should find the reason why you can't flash that softdevice.

Then, you should make sure the start address of burning is compatible with the softdevice.
