nRF52832 Custom Board External Crystal not working.

Hello All.

Recently we developed a custom board for a Node using nRF52832. Due to availability we used the nRF52832 QFAA Rev 2 on out board. This custom board was designed by using the reference design for the nRF52832. During testing we found that the External Crystal (32MHz) was not working and neither was the code or any sample code. We have confirmed that all components and their values used were according to reference design.

As of defining the custom board, we did define the custom board as the board porting guide suggested. We are not sure if there are any extra configuration options necessary to enable the External crystal, but scouring through the documentation I was not able to find any information.

The applications developed for the board used nRF Connect SDK 2.1.2 and onwards which did not work unless we forcefully switch to the internal LFCLK. On this thread we saw that the nRF Connect SDK 1.6.0 might utilize the external crystal attach Revision 2 of the SoC in question. But that was not the case as our board did not work. One board without the crystal dd show the initial prints for the Mesh Sensor Server sample code.

Are there any points we might have missed out or are there any software side configurations, etc that we might need to check?

SDK used: nRF Connect SDK v1.6.0
