How is the calibration routine in the Ghz ranges … 2 & 3Ghz ?
i calibrated a few months ago and have not since …
Is it time to run it again ?
I used the CLI
LimeSuiteCalibrate --freqStart 500000 --freqStop 3800000000
Is that still used ?
@joshblum has just merged some updates to calibration into the git master branch and should be able to comment further on this.
There were updates to the calibration routines on the master branch. In trying to match this, the SoapySDR wrapper now calibrates when the streams are first started using the LMS7002M::CalibrateRx/Tx()
The old cache may be an issue, I would try to delete ~/.limesuite/LMS7002M_cache_values.db
and should be be any lingering issues with the calibration cache, it can be disabled by passing “cacheCalibrations=0” in the device args
Iv tried the update from git …
Should the old cash be deleted?

Yes.
OK, im sure that the location of that cash is listed in the forum …
where is it located?
On Linux there is a db in the .limesuite dir (note preceding dot - meaning hidden) under your home directory.
.LimeSuite or .limesuite

Hey … does the calibration work for the microwave areas yet?
Just did a new calibration and noticed that even at 2.8Ghz calibration failed …

So, it looks as though something broke between these versions.
Try renaming or removing the only .db file in /home/.limesuite/
Also a reboot / sudo ldconfig …
Yup, did all those things.
Because unknown setting key seems suspect
And after trying on a more stable system … im still getting tge same error as you …
Im confused as to why this is happening … os it a bug or just a failure in the process of updating.
@joshblum any advice on how to proceeded?
Or @andrewback …
I got a segfault from LimeSuiteCalibrate. I’m using LimeUtil --cal instead. I just updated and recompiled from git.
After a sudo apt-get update / upgrade / dist-upgrade, it was working again … BUT
after starting a limited calibration 1ghz to 1.5ghz i wanted to do a single frequency – so i hit “Ctrl-C” to stop the program … it WAS working with out error.
after that i could not get the calibration program from having the for mentioned error !!! — ahhh COME ON !!!
I removed the .db file from .limesuite and made sure that the date/time was updated before the calibration routine was started …
tried the same thing with the Odroid-X2 — did not work.
Still not sure what the dividing line is …
Does Limesuite --cal do both DC offset AND I/Q image calibration?
hi
i get this error. how pair it?
