Zephyr NVS sample on nrf52840dk produced hardfault

[BvdP4Celsius]

I build the Zephyr NVS example that came with nRF Connect SDK version 2.7.0.

When using the nRF52840-DK and in my build config selected nRF52840 DK nRF52840, the application will crash.
I get an hardfault when using the Ozone debugger. The hardfault occurs at nvs_recover_last_ate(fs, &addr); in nvs.c 

Any idea how to solve this?

Hi,

 

Can you share the stack trace and possibly the debug assert message from RTT/serial terminal?

 

Kind regards,

Hope this helps.

Thank you for sharing these details, Bob.

It seems that your main stack size is going out-of-bounds. This is usually due to the stack size that is given to the main thread.

Could you try to adjust CONFIG_MAIN_STACK_SIZE to a higher value and see if this assert disappears?

 

Kind regards,

Håkon

Thanks Hakon,

CONFIG_MAIN_STACK_SIZE=2048

seems to work!

regards,

Bob
