I was following this [quicktest](https://wiki.myriadrf.org/LimeSDR-USB_Quick_Test), selecting the LimeSDR Mini is OK, but when I open the [self\_test.ini](https://raw.githubusercontent.com/myriadrf/LimeSDR-USB/master/test/limesuite/self_test.ini) file, it failes with these errors :

```auto

That guide is for LimeSDR USB, so it’s .ini file is not going to work for LimeSDR Mini, it needs different settings.

ok (should be specified in this online documentation) -\> is there a quicktest for LimeSDR Mini ?  
I’ve seen there is a huge [post](https://discourse.myriadrf.org/t/problems-with-limesdr-mini/2394/94) with similar error -\> let’s start a new one with a clear step by step quicktest for LimeSDR Mini with LimeSuiteGUI.

As far as I know, no.

I guess this one should be directed to @andrewback

There is a standalone self-test utility for Windows. See:

> [@Problems with LimeSDR mini](https://discourse.myriadrf.org/t/problems-with-limesdr-mini/2394/26):
>
> [Here](https://1drv.ms/u/s!AsTX3WCH_RLChkcEP2wP-RhKL8a0) is a link to test software for Win platform. There is a Visual C redistributable package included as well (just in case). Connect LimeSDR-Mini board and push Start test button to start testing. Log file will be created after test is complete. Share the log file, please. Regarding LimeSuiteGUI - yes, you have to push Default button after you connect to the board in order to set configuration for LimeSDR-Mini board.

Thank you @andrewback, but my platform is OS X 10.12.6 😉

This [post](https://discourse.myriadrf.org/t/self-test-not-working/2584) covers Windows only.

@Zack, do we have a Linux/Mac version of this utility in the works?

Is there an update on this? Any non-Windows quick- or self- test for the LimeSDR mini? @Zack
