Warnings that UICR has not been erased just after I erase it

[Scott Althoff]

I called these command:

nrfjprog -f NRF52 --eraseuicr
nrfjprog -f NRF52 --program app.hex --sectorerase

During the eraseuicr I see:

Erasing UICR flash area.
Applying system reset.

During the program I see:

WARNING: A UICR write operation has been requested but UICR has not been
WARNING: erased. Please verify that the result is correct.

Is there a way to properly erase the UICR so I don't get these warnings?

Yeah I missed that. Good to know :)
