Hi, I’ve been trying to use my limesdr mini v2 and I always get “TuneVCO(CGEN) - failed to lock (cmphl!=0)”, I’ve tried to update the device using LimeSuite --update and it says it’s already at the newest version of the gateware:
Connected to [LimeSDR Mini [USB 3] 1D90ED1C8222F5]
Existing gateware is same as update (2.2)
Using the CLKGEN tab on LimeSuiteGUI, Calculate and Tune yield the same error…
UPDATE: If I enable “Charge Pump” on the Power Down Menu, the Tune works and the High Vco Comparator turns to 1… But the issue still remains if I disable that option or if I use any software to access the device…
Is it possible to ‘‘fix’’ the device ? Thanks! All help is welcome!
Question, is there a document that talks about using LimeSuite? I am not a software person (primarily hardware?) and am having a problem relating to what I am looking at. Where can I find out what the configuration functions are, what they do and what the function’s limits are? In the case of configuring the correct antenna position, I can’t find the location on LimeSuite where I can make the change to the antenna. I have no receive signals of any strength using my Mini 2.4 board but have great signals using a different SDR board. My use of the Lime Mini 2.4 at the moment, is to track satellites in the 137.x MHz range and also in the S-band location - 2.2 GHz-2.3 GHz range. I noticed on the board spec’ sheet it says receive 2.2 GHz-2.3 GHz and 700 MHz to 900 MHz have a configuration for the filtering. What about the general coverage of 100 MHz to 3.7 GHz? I guess what I am looking for is a “LimeSDR Mini 2.4 Configuration Manual for Dummies” manual. Is there anything that fills that need?
I have never used this method of help before and could also use some instructions if there is any, so I use it correctly. I thank everyone for their assistance. I have also done something to my other board than has affected its ability to link, plus when I do try to link to anything it crashes my laptop. But that’s for another entry. – Gary
If you mean LimeSuiteGUI this is an engineering tool and not for general use.
End users should use SDR applications, along with plugins such as as the source/sink blocks for GNU Radio, which take care of all the underlying settings and leave you to just configure the operating frequency and bandwidth etc.
It is general coverage with no tuning gaps. However, different LNA inputs are optimised for different frequencies and sometimes the optimal range is shown in the documentation. This can lead to confusion and you should simply pick the LNA input with a stated range which is closest to your operating frequency.
So to sum up:
Don’t use LimeSuiteGUI
Pick an application with Lime Suite or SoapySDR support, else based on GNU Radio, which meets your requirements and read its documentation
When it comes to selecting an LNA input in said application, pick the one with a stated range which is closest to your operating frequency
