Is the RTT functional when APPROTECT is enabled?

With the nRF52, is the RTT functional when APPROTECT is enabled?

I would expect not since the RTT relies on memory accesses which should be disabled with APPROTECT

A ran a quick experiment and confirmed that the RTT is not functional when APPROTECT is enabled.

What do you mean by 'production build'? Do you have specific flags to indicate a production build?
