Fail to readback protection

[dong li]

I program the nRF2727 module with the "Block readback of mainmemory" seleted using nRFgo studio tool. After that, I can still read out the content of flash. What's the root cause?

The device must be reset in order to activate the block protection. Try power cycling the nRF6310 motherboard or pushing the reset button, then read out the memory.
