My LimeSDR Mini (v1.2) seems to have suffered a failure.
I had it running successfully for a few hours with CubicSDR. I paused the radio receive process, then came back to find the LimeSDR’s LEDs were off and CubicSDR had crashed.
I reconnected the LimeSDR - the LEDs remained off.
I tried LimeQuickTest – this reports “TransferPacket: Read failed” and “TransferPacket: Write failed” errors.
I’ve since bought a USB Blaster and set it up per this article:
And used Quartus Prime Programmer to reprogram the gateware with the image from:
If I load the HW1.2 POF file, the behaviour of the board doesn’t change - when plugged into the USB port the LEDs stay off.
If I load the HW1.2 SOF file, the LEDs light up and the board works okay. When unplugged from the USB port and reconnected, it goes back to the no-LEDs and USB-errors behaviour.
… Well, I say it works okay – I just tried again and I get a failure on the RF loopback test:

Is there anything else I can try to fix this board – or if not, how can I get it replaced?
