Readback protection and bootloader

[Lorens]

Hi, 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? I am thinking about this kind of solution: Lock the readback using UICR RBPCONF->PALL at the beginning of the application and Release the Lock when the boot starts. Could it work? Is there a better solution?

Thanks

The bootloader will have no problems trying to read softdevice information if readback is enabled. What kind of problem do you see here?

you cannot release the Lock one you have done RBPCONF->PALL. This is because once you have written to this register, you have to erase the whole chip to unlock.

The problem I saw was that using the Bootloader I couldn't Upgrade the fw, while configuring the register as I told You it seems to work. Lock, release and lock again.

Thank you
