In the above line there is an error causing gdb to print this error:

Python Exception <type 'exceptions.AttributeError'> SVDRegisterCluster instance has no attribute 'parent': 
Error occurred in Python: SVDRegisterCluster instance has no attribute 'parent'

when accessing register cluster.

Tested on nrf52840 chip + black magic probe. With command:

svd POWER RAM[0]

changing line 273 to:

container = peripheral.name + ' > ' + cluster.name

solves the issue

Good catch. The fix should work as far as I can tell.
