This is a good resource, but you should also note that the SoftDevice will trigger a HardFault purposefully when a stack fault happens. Before it happens, the fault handler given to sd_softdevice_enable should be called though. If this is not the case, it's one of the default ARM HardFault reasons (unaligned access or overflow most likely).

Hard Faults and their handling are part of the ARM Architecture - not specific to Nordic.

I collected some references here: community.arm.com/.../5414

When working with ARM Cortex-M, you should certainly have a copy of Joseph Yiu's "Definitive Guide" book - they have sections about fault handling ...

There has been a lot of post regarding it. I am just pointing to few of them.
