Hi All, Sorry for starting new thread, I've just subscribed to the list and can't repy to old thread.
I also see a lot of aforementioned errors when I try to run OpenBTS. And I see them regularly, not occasionally. I use Ubuntu 9.04 x64 on IBM/Lenovo ThinkPad T60. It uses ICH7 for USB. I can provide 'lspci -v' later if needed. I experienced these errors when I ran OpenBTS's transceiver with non-realtime priority. When I run it with realtime priority (Round Robin with 80 priority) I do not recall to see them. Even then I still see regular "TRX-> USRP Underrun" messages, but that's for another topic, I think. So my guess is that this is somehow related to scheduling and may be caused by bursts of writes to USB. PS I use OpenBTS 1.6 which use its own fpga code. -- Regards, Alexander Chemeris. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
