It takes a super long time to build and run nRF5340 code

[StevenW807]

Previously, I used SEGGER to build and run programs on nRF52 DK very quickly (5-20 seconds).

However, for nRF5340 DK, it usually takes about 8-15 min to build and run just 1 example program. For example, here is the nRF5340 DK beacon example project build and run time duration (17min 45sec in total):

Especially for this step, it takes a long time: 

Is that normal? Why nRF5340 DK takes so long time to build and run the program, please? If I need to upgrade my laptop hardware, what's the key performance which my new laptop need to improve (such as better CPU, multiple processors)? Here is my laptop performance data: 

Thanks!

Hello Steven,

However, I cannot use SEGGER to directly download the "build and run" project to the board (see screenshot). Any idea why, please? Thanks! 

 have you installed the nRF Command Line Tools?

 Just a little thing to double-check, though: is it on purpose that your are building for the network and not the application core?

If you build the same program outside of SES from a terminal, does that make any difference?

 What I actually meant here was something like this:
