Approtect with zephyr

[Dymek117]

I'm not sure if zephyr questions can be also asked here.

Problem I am struggling with is approtect mechanism to prevent flash readout. I am trying to use Zephyr config files to eneble such options (doing this by register can be ovewritten by zephyr), so according to zephyr docs i'm setting up this options in it's config files:

CONFIG_NRF_APPROTECT_LOCK=y

But anyway, after build and flash, NVM can be easily readable by nrf programmer. So i guess I'm missing something.

Hi,

Which versions of the nRF SDK and which board are you using?
Please note that you could use command nrfjprog --rbp ALL for disabling readout protection.
