The Question of app_error_fault_handler.

[hongpal]

Hello Nordic!

I'm developing with nrf52840, s340, and SDK 15.3.0

Sometimes, I got an error in app_error_fault_handler. 

This is information that gives me in app_error_fault_handler.

Received a fault! id: 0x00001001, pc: 0x00061c94, info: 0x00000000

SOFTDEVICE: INVALID MEMORY ACCESS

I know this problem is violate at softdevice section. 

pc location is memset fuction.  I want to know return address sins memset finised.

How to do that ? 

[hongpal]

If I do memset start at 0x1000, I don't need to check out and I don't get any error. is it right?

I don't understand yet. Why do the starting point indicate crossing the Softdevice boundary.

[Vidar Berg]

The starting point may point to one of your variables. Then you could check where that variable is set in your code. Anyway, have you reviewed each call to memset. And to you know the exact steps to trigger this fault? 

[hongpal]

I will try to review each call to memset next day. 

But, I don't know the exact steps to trigger fault.

[Vidar Berg]

Ok, I think it's a good start. Let me know if I can help with reviewing these calls, or debug your code.
