Re: [Discuss-gnuradio] GNURadio on Zync: thanks for the excellent tutorial

Damn I missed all these replies to my initial post due to not being familiar
with our webmail interface and not having access to the lab for the last
8 days. I hope I have not done anything stupid by not taking into account
the comment about having to wait for the OE update: I have tried to add my
own comments to the Zynq wiki page but not being familiar at all with OE, some
of these comments might be overly naive (I believe not wrong, since these are
the steps I took to get to the point of compiling the FIR on FPGA example).
Some knowledgeable person should definitely review these updates to the wiki
page.

At the moment, I am stuck with two issues:
1/ eth0 will not start when booting linux on the Zynq with the current kernel,
so no git/opkg install from the web at the moment (makes the software update a
bit complex by keeping on putting the SD card back in the PC connected to the
internet)
2/ cmake does not find gnuradio-runtime: I am pretty sure this is an issue
with the outdated FindGnuradioRuntime.module issue but I have not yet managed
to get gr_modtool to run ... still working on it.

I assume my addition to the wiki on the installation of cmake is not
erroneous,
but should be checked as well.
