[What happens instead e.g. error message]

Steps to reproduce the problem

[Tell us how to reproduce this issue e.g. RF setup, application config files]

Additional Information

[Any additional information, configuration or data that might be necessary to reproduce the issue]

[TheDuchy]

Same here with a x40 board. Previously discussed here: #373. Issues looks like an upstream issue with libbladerf.

[andrepuschmann]

The issue is currently investigated by the folks at Nuand. See here.

[jarek556]

Temporary solution: use FPGA firmware version 0.9.0.

[yesimxev]

Temporary solution: use FPGA firmware version 0.9.0.

Does not help for me, still experiencing the same issue

Using the latest github repos, and also tried fpga from 0.12 to 0.8

  bladeRF-cli version:        1.8.0-git-e09200c3

[bmigunov]

Same(?) issue when I'm trying to set eNB up with bladeRf x40 as the RF-frontend.
srsenb output:

The new version of SRS does not give me this issue anymore. Update everything on the blade and SRS
