Hello @Aarti_18

This is the setup sequence I’ve used for all the involved SW:

**01-windows-usb-driver**  
that you can download from [this page](https://wiki.myriadrf.org/Lime_Suite#USB_driver)  
on windows this driver is needed to have the board properly recognized

**02-PothosSDR**  
that you can download from [this web folder](http://downloads.myriadrf.org/builds/PothosSDR/?C=M;O=D)  
after this setup you can download just the LimeSuiteGUI exe file downloading the most recent one from [this web folder](http://downloads.myriadrf.org/builds/limesuite/)

**03-SDR-Console V3**  
you can download this wonderful program from [this web page](http://sdr-radio.com/v3_preview_downloads)

**04-quick-test-files**  
you can download the files from the [quick test page](https://wiki.myriadrf.org/LimeSDR-USB_Quick_Test)

**05-FPGA-fw-update**  
I have performed this step from within the LimeSuiteGUI

**06-HF-MOD**  
I did this just because I’m working at HF frequencies. Seems not needed at other (higher) frequencies.  
Instructions are [at this web page](https://www.crowdsupply.com/lime-micro/limesdr/updates/optimising-performance-on-hf)

**07-IQ-calibration**  
you can run the Python calibration program \PothosSDR\bin\LimeSuiteCalibrate.py

bye,  
mario

@mariocannistra : Thanks for your reply. One more question, I am planning to install eNodeB Stack from OpenAirInterface using ubunut 16.04 OS. Is there any pre-requirement for the same ? Thanks In advance.

Sorry, I don’t know OpenAirInterface, but i see here a link to hw and sw requirements: [http://www.openairinterface.org/?page\_id=25](http://www.openairinterface.org/?page_id=25)

…actually…seems there are lots of details to check and set…

Hello @martywittrock you’re welcome ! 😄

When I install something new, I usually create separate folders with bookmarks, then I number them when I’m sure of the sequence… you know… sometimes i have to reinstall after months when changing PC or OS and… I can’t remember everything… 😄
