Projects LimeSDR

Hello

I just removed my LimeSDR Mini V2 from my PortDown Box which had been working
very well, as I was going to mount into a metal case, until this is had been
working extremely well since I received it

When I plugged the lime back into my computer later on I have found that it
does not how any LED’s and also is UNKNOWN
Is there a version of firmware that I can try and reflash this with and how do
I got about this

Any assistance would be greatly appreciated
Regards

Hi Ray,

Sounds like we know what the answer will be, but as a first step can you run LimeQuickTest and post the results. There should be nothing connected to the RF connectors when you do this and it should be plugged directly into a USB 3.0 port on your computer.

Cheers,

Andrew

This is a really old version of Lime Suite and dates back to before LimeSDR Mini v2. The Pothos Windows installer needs updating and in the meantime is there a Linux computer you could try this from? You should have the latest version of Lime Suite, v23.11.0, installed.

Hello Andrew,

Where do we find the latest version of the pothos installer, the website downloads.myriadrf.org/builds/PothosSDR/
installs “LimeSuite version: 20.10.0-PothosSDR-2021.07.25-vc16-x64”

The Pothos software is maintained by a third party and as I say, the Windows installer needs updating and if you could please try using a Linux computer, unless you are comfortable compiling Lime Suite for Windows.

Hello Andrew

I have the same test on a Linux Machine and the only difference was the last 3 lines as show above

Just wondering if the process is any different for a V2.4 board to what I have been reading, as I dont seem to be able to reflash the SDR ATM

This indicates that either board is not receiving power or FPGA gateware is not loaded properly from FLASH memory.

Check FAQ section:
I cannot connect board to LimeSuite GUI, no LEDs are blinking how can I recover my board?
