nrfjprog --readcode returns error

[Robin]

I am trying to use nrfjprog.exe (for the first time) to see if my code is being corrupted on a power fail.  It keeps returning an error that I can find documentation on.

Here is the command and the errors:

C:\Program Files (x86)\Nordic Semiconductor\nrf-command-line-tools\bin>nrfjprog --readcode after.hex
ERROR: The file specified is not a valid hex file, has data outside valid areas
ERROR: or does not have data in valid areas.

Please help

that exact command works fine here.

Try to see if any other commands are working and try to get some logs out of it and post the logs here

nrfjprog --readcode after.hex --log log.txt

Hello Susheel,

I found the version of the command line tools that aligns with the Segger install I am using. So it appears all in working now.

There is an issue with finding this alignment though.  I was pretty lucky in my choice.  The change notes on the site are not all consistent in there content.  I would recommend that the site have this alignment clearly stated somewhere.

I will close this case when I hear from you on this software alignment concern.

Thanks endlessly,

Thanks for letting us know about this Robin. Do you mean that command line tools have a specific segger driver version to be installed to work? Normally, command line tools also prompts to install segger drivers. I am guessing that there was some change in either command line tools or segger that happened to be incompatible. Good that you figured it out and got it working.
