Errors running LimeSDR on GNUradio

Projects LimeSDR
1

Hello,

We will be running a basic flow graph to test our antenna with the LimeSDR.
The flowgraph is basically an osmocom source–> WX GUI waterfall sink.

It will run perfectly fine for some operations and then every once in a while we will run it and get this error. It then works fine after we hit the reset button on the LimeSDR.

We will get this error.

Ocassionally, we also get this error as well:

If anyone knows what is going on, that would be great.

Looks as though you are using USB 2.0 and so it may not be getting enough power. This is often the case when not using USB 3.0 and you see the gateware mismatch error “But found version 0, revision 0”.

On the other hand, I got similar symptoms even when using USB 3.0 ports on different computers, and in the end was advised to contact CrowdSupply for a replacement.

That may be the case, but I think we need to first exhaust all other remedies before we start arranging RMAs, otherwise we risk wasting the time of board owners, Crowd Supply and the engineering team.

You are absolutely right! :slight_smile:

Thank you, we will order a power supply for the LimeSDR and test it out. Any recommended power supplies? I know it has to be in between 6 and 12 v.

I’ve not had cause to use one yet. @Zack, is their a particular power supply you have used or would recommend?
