Hello All,
We have custom PCB having ATSAME54P20A microcontroller. Suddenly today I started getting CPU Status - LOCKUP error and I am unable to download the code to the microcontroller. Before, that I am able to download the code to controller but it is giving me various BusFault and HardFault handler errors.
I am using IAR Embedded workbench environment and ATMEL ICE debugger to download the code to controller.
How can I download the code to controller again ?? How to remove the LOCKUP state of Cortex M4 device ATMSAME54P20A ?? What steps I need to take to resolve this issue ??
Please, help.
Thanks.

So why have you posted in the ARM Development Studio forum ?
You'd be better on Microchip's dedicated SAM forum:

Hi Andy Neil , Because the problem is related to Atmel ATSAME54P20A device, which uses ARM Cortex M4 architecture and the given problem is related to the LOCKUP state of controller which is mentioned in the link below:-
https://developer.arm.com/docs/dui0553/a/the-cortex-m4-processor/fault-handling/lockup
So, that's why I posted it over here.
The article in the link given above doesn't provide in detail how to solve this error. If you know how to solve this behaviour of controller please help me out.
But you have posted in a forum specifically for the ARM Development Studio - and you are not using the ARM Development Studio
OK I will move it from here. Anyways, do you have any idea about the above issue then please help.
I have moved it to Community help forum. Can you help me with above issue if you have any idea ??
