Hi @samvidh,

Which RTD revision do you use?

Can you provide more information about the fault exception?

Hello @samvidh,

The image you posted does not say anything.

You should be able to identify the type of the fault exception.

Since you changed the linker file, it can be caused by the MPU (MemManage Fault exception).

Is this the only change you made in the linker file?

Can you share the whole project?

Regards,

Daniel
