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.
