Hello,

I updated my N320 to UHD 4.6, however now I am getting an error in GNURadio:

"RuntimeError: RuntimeError: MPM major compat number mismatch. Expected:
4.2 Actual: 5.3. Please update the version of MPM on your USRP device."

Any suggestions on how to fix?

Thanks,

Steve

You need to install a new image on your USRP via mender or manually. I had to do this recently to fix the same issue. See "updating filesystems with mender" in the docs.

Yeah, that is what I figured. Any suggestions on what to do? I tried uninstalling and reinstalling gnuradio as well as installing UHD4.6 on my host PC. I'll ask the gnu-radio mailing list too.

Thanks,

Steve

Your Gnu Radio install probably is linked against an older version of UHD, hence the mis-match.

If you’re going that way, you need to revert yuur N320 to an older version. LookMore closely at the error message.

Oh, you’re right, the other direction. Look at your host binaries with “ldd” or another tool to see which libraries are getting linked in. My guess is that you’re still linking to the older version.
