Alexander Chemeris alexander.chemeris at gmail.comHi Stephane, Glad to see first users starting to play with UmTRX. :) Please use OpenBTS from our repository and use branch "umtrx" instead of "master". UmTRX support is not merged into master yet. git://github.com/fairwaves/openbts-2.8 umtrx "Failed to set master clock rate" error is thrown because it thinks you're using USRP N and tries to set frequency accordingly. FPGA image should be the latest. You could download it here as well: http://people.osmocom.org/ipse/umtrx-v2/fpga_bitsream/2013-02-03-394f48b7/ We'll look into the FPGA compilation issue - may be Andrew forgot to check in that file. Thank you for reporting this.
