Zigbee_coordinator and Light_bulb cause BUS FAULT on nRF5340dk

[CrisT]

Hello,

I've been trying to learn to develop an app based on ZigBee, it's the first time i'm working with nRF hardware and the only things i've done so far was to run some examples. 

When running either of the two ZigBee examples, I noticed the boards are not working so i checked TerraTerm and the board is just continuously writing this:

I am patiently waiting your advice and thank you in advance for support

Hi,

What error are you getting? In the Output window in SES (Segger Embedded Studio) you can select to show Transcript and Output, and it will show you a log of the build process. Please copy the log and add it here by either uploading it as a .txt file or using Insert -> Code, so I can help you with this error.

I tested compiling for cpunet now myself to make sure it works, using SES and NCS v1.5.1, and I did not get any errors. I have not made any changes to this project, so it should work out of the box. Be aware that it is only the nRF IEEE 802.15.4: Serialization RPMsg sample you should build for cpunet. The build target for the network coordinator should still be cpuapp.

Best regards,

Marte
