nrf52832 hardfault after disconnection

[GordonHuang]

We are testing our custom board using the the dimming_server example from mesh 5.0 sdk. This example runs fine on the PCA10040 board. On our board, the provision runs normal using the Nordic Android mesh app. However, when we disconnect the node after provision, the code will crash and hit the 0x00000A60 after couple seconds.  And no trace information available for debugging.  All the operations and communication between android app and device are normal if we do not disconnect the node after provision. Please give us some advice on this problem. Thanks

Hi.

Hard to say what could be the root cause without any more specific information.

Is it possible to debug the node while disconnecting?

You can use the addr2line tool to see which part of the code that 0x00000A60 matches.

As the example is running fine on the nRF52-DK I would suspect something with your custom board.

You can upload your schematics and I can have one of our engineers review it.
