Title: YateBTS + bladeRF unstable
Post by: sertys on August 22, 2016, 08:05:58 AM

I am running the latest Yate + YateBTS from releases page and trying to run my little base station.
Going through a lot of combinations of FPGAs and firmwares got stuck with :
bladeRF-cli version:        1.4.0-2016.06-1-ppatrusty
  libbladeRF version:         1.7.2-2016.06-1-ppatrusty

  Firmware version:           1.6.1-git-053fb13-buildomatic
  FPGA version:               0.0.3
as it at least starts my BTS and i can find it on the phones.
The problem however is that it is extremely unstable, runs for a couple of minutes and then gives me :

Which basically kills the transceiver and restarts it over. Can you shoot me some pointers onto how to fix the issues and have a stable BTS at hand?

As pointed in the IRC channel, this issue is due to a low cpu and/or usb3 drivers on a ubuntu system.
I changed the host to a more powerful one (i5 cpu and proper usb3) and it is running without a hitch now.

Hi there,

Experiencing the exact same problems. I am running an i5 so CPU is not a problem. Looking at lsusb -t and usb-devices it looks like Im running USB3. Switching to "proper usb3" was a recommendation in the thread - in an ubuntu-context; what is proper USB3? External drivers not part of Ubuntu distro?
