Hardfault at 00000008 CONFIG_NUM_MBOX_ASYNC_MSGS

Hello,

I have an application and I am using a nrf52833, as soon as i flash my application I am getting a hardfault prior to the main call.
As in below snap:

I do not know what to make of this, kindly suggest.

Thanks,

  • Hello,

    I found the source of hard fault issue.

    I wanted to have memory partitioning, for which I edited the "pm_static.yaml" file and "bl653_dvk.dts" files

    As soon as I removed the "pm_static.yaml" from my project, The restart was not happening and image is working fine.

    Please fine the below attached files and kindly suggest what is wrong with my "pm_static.yaml" file:

    Regards,

  • Yes, I added a new pm_static.yaml into project

    pm_static.yaml" file:

    I think something wrong here

  • Can you check my pm_static.yml file and see if anything wrong there..?

    As soon as I removed the "pm_static.yaml" from my project, The restart was not happening and image is working fine.
  • Have you made any changes to the pm_static.yaml file?

    Hi ,

    Can you help me figure out what is wrong with the defined file..?

    "pm_static.yaml" file:
