https://devzone.nordicsemi.com/f/nordic-q-a/7578/readback-protection-and-bootloaderHi, I have a problem configuring readback protection using boot. It seams that the BOOTLOADER stops when trying to read some information from the softdevice if readback protection is enabled. May this be the issue? How to solve the problem?

Lock, release and lock again.</p> <p>Thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/27018?ContentTypeID=1Fri, 12 Jun 2015 09:23:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:68509013-6753-4da1-ad61-b835b9ddddb6Susheel Nuguru<p>The bootloader will have no problems trying to read softdevice information if readback is enabled. What kind of problem do you see here?</p> <p>you cannot release the Lock one you have done RBPCONF-&gt;PALL. This is because once you have written to this register, you have to erase the whole chip to unlock.</p><div style="clear:both;"></div>
