nrfutil fails with " Application file not found." but return code is 0

[dgerman]

nrfutil version 2.3.0 correctly fails with message  " Application file not found." but incorrectly sets the return code to 0

Hello,

Do you have a particular reason to use such an old nrfutil?
I tested using nrfutil v6.1.0 (current version), and in that case nrfutil settings generate returns 1 when the application .hex file doesn't exist.

Either way, I guess it is fixed at this point. I don't see it very likely that our nrfutil team will go back and create a new nrfutil 2.3.1 version.

Is upgrading nrfutil an alternative for you? Or do you have another way of working around this issue? To be fair, I wasn't aware that this returned anything until now.

Best regards,

Edvin

Sorry. I didn't realize the version I was using was old.
Thank you.

I updated nrfutil (under Mac OS Big Sur (oops)) and now I can not longer run nrfutil !

From the  pyserial (rather lengthly) issue at GitHub :

It seems that Apple has removed kIOMasterPortDefault from the iokit library.

From the macOS Big Sur release notes (https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11-beta-release-notes): ...attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail....

Is this something that Nordic development needs to address?

Should I create a new problem :"nrfutil fails on Mac OS Big Sur" ?

[Edvin]

Try updating to python 3.8.x. I use v 3.8.7.  I don't have any knowledge with Mac OS, but please check the discussion in this ticket:

https://devzone.nordicsemi.com/f/nordic-q-a/68518/nrfutil-on-osx-big-sur-fails-to-execute-symbol-not-found/286199#286199

I noticed that your Big Sur release notes link is a beta release. Do you have the beta release, or the final version? If not the final, can you try to upgrade? 

And yes, check the discussion on pyserial in the link above, and let me know if updating pySerial doesn't work either.

Best regards,

Edvin
