Hi, I am trying to compile dtv module for gnuradio on E312 target hardware.
I am following below grc code for reference: https://github.com/gnuradio/gnuradio/blob/master/gr-dtv/examples/dvbt_tx_8k.grc https://github.com/gnuradio/gnuradio/blob/master/gr-dtv/examples/dvbt_rx_8k.grc After few parameter modifications, these examples were successfully executed using Ubuntu host and UHD sink/source specified as two E312 hardware. However since dvt module is not available on E312 by default, I tried using cross-compilation sdk from below path: http://files.ettus.com/e3xx_images/e3xx-release-4/ I have followed below steps for cross compilation: https://kb.ettus.com/Software_Development_on_the_E310_and_E312 However, after installation of cross-compiled code (make install DESTDIR=<sshfs root mount>), manually executing the generated python file gives below error: root@ettus-e3xx-sg3:~/Kailash# python dvbs2_tx.py linux; GNU C++ version 4.9.2; Boost_105700; UHD_003.009.002-0-unknown -- Detecting internal GPSDO UHD Error: An error occured making GPSDd interface: RuntimeError: Failed to connect to gpsd: can't connect to host/port pair Initializing core control... -- Performing register loopback test... pass Traceback (most recent call last): File "dvbs2_tx.py", line 130, in <module> main() File "dvbs2_tx.py", line 124, in main tb = top_block_cls() File "dvbs2_tx.py", line 45, in __init__ channels=range(1), File "/usr/lib/python2.7/site-packages/gnuradio/uhd/__init__.py", line 122, in constructor_interceptor return old_constructor(*args) File "/usr/lib/python2.7/site-packages/gnuradio/uhd/uhd_swig.py", line 2074, in make return _uhd_swig.usrp_sink_make(*args) RuntimeError: RuntimeError: Expected FPGA compatibility number 14.x, but got 16.0: The FPGA build is not compatible with the host code build. Please run: "/usr/lib/uhd/utils/uhd_images_downloader.py" Executing /usr/lib/uhd/utils/uhd_images_downloader.py python script is no help as FPGA version still remains the same. Any help here would be appreciated. Thanks in Advance. Regards Kailash
