Yes, I understand its for testing only.

If the CC3XX driver wont even compile on the nrf5340ns then it probably shouldn't automatically be enabled for that target.

Hi,

I want to mention that in case it was not clear, using CONFIG_TEST_RANDOM_GENERATOR gives you pseudo random numbers and not true random numbers. So it enables you to develop and test your code, but you cannot use this in production.

There will be support for using the CC312 from non-secure region in the future, but I cannot say exactly when that will be.

I was able to get it to compile by adding

CONFIG_TEST_RANDOM_GENERATOR=y CONFIG_ENTROPY_CC3XX=n

to the prj.conf.
