Code protection

[[email protected]]

We want to protect our firmware code from hacking/reading back. Is there a way to configure this inherently in the application or bootloader code so when it is loaded into the chip, it automatically is locked from the code being read out of the chip?

Hi, 

What build codes of nRF52811 are you using? You can take a look at the nRF52811 Access port protection.

Not sure where to locate the "build codes"

Is this what you mean?

NRF52811-QCAA-R

So if I understand this (which is an overstatement) - it inherently protects it unless otherwise disabled/changed?

Thanks,

Kevin Lamb

Hi, 

See SoC revisions and variants

the top of the chip reads;

N52811

QCAAA0

2242AF

I take it that means it's revision 1; Ax0?

I think so. Then, you can use the command "nrfjprog --rbp ALL" to enable the readback protection mechanism.
