limesdr-mini's Issues

LimeSDR-Mini firmware

Hello world :-)

We are porting LimeSuite to FreeBSD. Working on LimeSDR-Mini. There seems to be a set of issues with LimeSDR both USB and radio part. Where can we find source code repository and support for those issues?

Identified issues so far:

1. LibUSB open / reset impossible on FreeBSD when working as user (only root can reset hardware USB ports).
2. Hardware Self-Test fail with LimeQuickTest.
3. MCU error 3 / Tx Calibration: MCU error 3 (SXR tune failed).
4. MCU error 5 / Tx Calibration: MCU error 5 (Loopback signal weak: not connected/insufficient gain?).

The work in progress is documented here:

Step File doesn't show mounting holes

I am attempting to create a 3d printable case for my new Mini. I downloaded the STEP file for the board and noticed it does not have the two mounting holes up near the USB connector nor the 4 side cutouts. Would it be possible to get a new STEP file that has these in it so I can build my case around them?
