Hard Fault when using bluetooth mesh examples

[SørenHN]

When programming the bluetooth mesh light control demo example found in the bluetooth mesh SDK, i get this error using J-Link RTT Viewer:

0> <t:          0>, main.c,  116, ----- BLE Mesh Light Control Server Demo -----
0> <t:       1391>, main.c,   84, Initializing and adding models
0> <t:       1441>, nrf_mesh_sdk.c,   76, HARDFAULT...

I am programming the server part of the example to nRF51422 on a PCA10028 dev-board, using S130 Softdevice.

I have not altered the source files and can't figure out what the problem seems to be.

Edit It seems to be this function causing the hard fault:

nrf_mesh_node_config(&config_params);

When commenting out the function i don't get any errors, but of course the program won't run then.

Hi Hvem,

Please make sure you erase the flash completely (use ERASEALL) before you test. Most likely this error occurred because of the wrong data in flash.

@Hung Bui. I have done that, and i still get the hardsfault error when using J-Link RTT Viewer.

How did you flash the softdevice ? Please don't use nRFGo Studio and don't select softdevice protection. Try to use SES to flash (it will flash both the softdevice and the application) instead of nRFGo Studio. I attached the light control server I compiled on my computer, if you need to test.

light_control_server.hex

What is SES? I have never heard of it. And why should i not use nRFGo Studio to flash the chips?

SES is Segger Embedded Studio. nRFGo Studio is deprecated soon, you should consider use nrfjprog for programming, especially when testing mesh.
