LimeSDR Mini RF Loopback Test Failure

Hi, there

I got a LimeSDR mini a couple weeks ago, but it won’t work properly.
The LimeQuickTest always fails with the error “SetPllFrequency: error configuring phase”.

I found the following thread and tried to change USB power supply but it didn’t help.

The followings are LimeUtil and LimeQuickTest log.
I got the same error on a Window10 host.

I would very appreciate your help.

Hi @minoru,

It looks like there is interface issue between FPGA and RF transceiver on your board. Contact Crowd Supply for replacement, please. Sorry for inconvenience.

Hi Zack,

I’ll contact Crowd Supply soon.
I appreciate your help.

Thank you,
