Hello
I'm trying to get the osmo-trx-lms to work with my LimeSDR. the setup is the latest version of LimeSDR and osmo-trx built from source with the command (./configure --with-lms) . I can see the device through LimeUtil but when I try the command it fails with the following error

I tried using the configuration file from the osmo-trx git url and the below file as well. both gave the same result.

Any ideas? Thanks Bahaeddin Sagar
Hi Baja,
this questions is better discussed at openbsc@lists.osmocom.org, where we discuss the GSM stack related projects. The osmocom-sdr mailing list is for osmo-sdr, rtl-sdr, osmo-fl2k, gr-osmosdr and related projects.

It is a permission problem. You need to be root to set a SCHED_RR priorirty.
