Hardfault at 00000008 CONFIG_NUM_MBOX_ASYNC_MSGS

[Ubaid_M]

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:

Have you made any changes to the pm_static.yaml file?

[Ubaid_M]

Yes, I added a new pm_static.yaml into project

I think something wrong here

[Ubaid_M]

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