[Discuss-gnuradio] Gnuradio over Zynq

   I would like to run the example from the GNURadio adaptation for Zynq (http://gnuradio.org/redmine/projects/gnuradio/wiki/Zynq), but I am not able to run it, it gives me a coredump.

 I managed to create the bootable card, at least I think so as the example does not work.

 What I did:
zedboard> cat zedboard.bin > /dev/xdevcfg
zedboard> cat /sys/devices/amba.0/f8007000.ps7-dev-cfg/prog_done

zedboard> ./zynq_fir_filter_example
Read the FPGA status...
/sys/devices/amba.0/f8007000.ps7-dev-cfg/prog_done = 1
Setup the driver...
Segmentation fault (core dumped)

zedboard> file zynq_fir_filter_example

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

The compilation of the example was OK, no error, the compilation and installation of gr-zynq module, the same.

Have some one else tried this zynq  implementation recently?
