LimeNET Micro 2.0 DE Initial Setup

General Discussion
1

Hi all,

I ordered a LimeNET Micro 2.0 DE from mouser. After installing LimeSuite NG with the instructions given in https://limesuiteng.myriadrf.org/gettingstarted/linux/packages, I can open LimeGUI. However, when I try opening the FFT module, it segfaults. Trying to receive using the CLI also throws an error. I suspect it is a driver issue. Following the default instructions for building from source resulted in the same errors. Any idea how this can be fixed, or is there a raspberry pi image with LimeSuite NG already working available?

Thank you!

Hi, can you check the gateware version using clilimeDevice -f?

I suggest you update the gateware https://github.com/myriadrf/LimeSDR_GW/raw/refs/heads/master/bitstream/LimeSDR_XTRX/LimeSDR_XTRX_user.bin

limeFLASH --target FPGA/user-image LimeSDR_XTRX_user.bin

What is your OS and kernel version (uname -a)? Did you remove the limesuiteng packages before installing it from source?

It seems that I did not properly remove the limesuiteng packages before installing from source, and now that I have done so + updated the gateware, it seems to work! Thank you.

For reference for others, below is uname -a. Everything was straight out of the box, no modifications.

lime@raspberrypi:~ $ uname -a
Linux raspberrypi 6.12.34+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.12.34-1+rpt1~bookworm (2025-06-26) aarch64 GNU/Linux

LimeNET Micro 2.0 DE comes pre-installed. Why you opted to install LimeSuiteNG again?

I guess I did not try it initially and assumed it was not. Whoops.
