nRF Progammer v2.3.3

[Learner]

Hello,

While programming my board with a merged.hex I sometimes see some differences at the end of the Programmer log.

Sometimes the log ends like this,

2022-03-25T14:05:24.026Z DEBUG Usage data has been sent
2022-03-25T14:05:24.026Z INFO Loading readback protection status for Application core
2022-03-25T14:05:24.662Z INFO Readback protection status: NRFDL_PROTECTION_STATUS_ALL
2022-03-25T14:05:24.671Z INFO Parse memory regions for Application core
2022-03-25T14:05:24.675Z INFO Device is loaded and ready for further operation

and other times it ends like this,

2022-03-25T13:49:15.964Z DEBUG Usage data has been sent
2022-03-25T13:49:15.964Z INFO Loading readback protection status for Application core
2022-03-25T13:49:16.725Z INFO Readback protection status: NRFDL_PROTECTION_STATUS_NONE

The programming of the target board looks as if it succeeded but I am concerned something else went wrong e.g. the SoC protection is not enabled.

Which of the two programming sessions have completed successfully?

Does it mean I need to reprogram the boards when I get NRFDL_PROTECTION_STATUS_NONE?

Can someone please explain what is going on here? 

Thank you.

Kind regards

Mohamed

Hi Mohamed

The PROTECTION_STATUS_NONE should mean that the readback protection is disabled (not protected). Please double check whether you are able to get this not protected message with a board where you have enabled readback protection in the application, I don't think that should be possible.

If you do, please open the console in nRF Connect for Desktop by pressing ctrl+Shift+I and take a screenshot so we can take a look, and we'll investigate.

Best regards,

Simon
