[srslte-users] srsLTE on raspberry pi 4

Mon Dec 2 12:52:49 UTC 2019

Hi List,

After your successful messages regarding PI 4, I thought I should give it a try (together with a B210).

But it looks like it does not have enough buffers/speed/etc..
Any ideas?

The first start after compiling the software took also a few minutes, I have no idea what the software does, but only after waiting that long it started transmitting. All further starts went almost immediately.

I got the LimeSDR-mini and enodeb is not starting(same with LimeSDR in USB 2.0 port ).

Here is the info:

I have found that the LimeSDR works fine when I connect it to an USB2.0 port, and only makes trouble on the RasPis USB3.x ports.

Thanks srsLTE is compiled, have you managed to run it with the LimeSDR or with the LimeSDR-mini only?

SoapySDR and Lime softawre are installed  i even tried with a power supply to the SDR, but the eNodeb is not starting.

I did with RasPi 4 and Raspbian. At least it was necessary to comment out some stuff; however just search earlier threads in the archive, it is all there.

Hi,

Has anyone been able to compile srsLTE in raspberry pi 4, OS:Ubuntu 19.10, arm64.

Best regards.
