NRFJPROG ERROR return code 9

[Chris Alfred]

We are developing a test jig that also programs the Nordic nRF51822 on our board.

We are receiving the following error message from the command line programmer: NRFJPROG ERROR: nrfjprog encountered an error condition that should not occur. Please report the error to Nordic Semiconductor support with the text "write_and_verify_hex_file: return code 9"

What are the conditions that cause this error?

[Chris Alfred]

We have generated non-overlapping hex files and we have not seen the return code 9 reported.

However, we are very concerned that the programmer was not consistently failing if it really can not handle overlapping files - what was it doing when it did not produce the error!

As we a programming thousands of the nRF chips in production, we need to absolutely sure the programmer is programming correctly.

I am glad that your problem is now sorted out. Don't be too worried about the inconsistancy of that behaviour, IF the tool did something that it was not supposed to do, then you will see it immediately when your application does not do what it was supposed to do. And We have not seen any such things yet. Keep an eye for new releases, we are always improving :)
