[USRP-users] Cross Compiling for N310

[Tellrell White via USRP-users]

I'm currently building an application that I want to run on the N310. I'm 
following the link attached

where I've downloaded and installed the sdk toolchain and set the necessary 
paths, however, is it necessary as well to cross-compile UHD as well for the 
N310??

Do you really need to install uhd on a machine to install an sdk on it?

Re: [USRP-users] cross-compiling for N310

[EJ Kreinar via USRP-users]

If I recall correctly the only place QT is used would be in the RFNoC
Fosphor host code to display the fosphor output. This typically runs on a
PC, not an embedded device like E310 or N310. Unless you really need to use
QT on the N310, definitely the easiest solution here would be to just
disable qt for gr-ettus.

I usually disable QT in gr-ettus for my cross compile builds using `cmake
..  -DENABLE_QT=OFF`

Hope this helps,
EJ

Re: [USRP-users] cross-compiling for N310

[Jason Matusiak via USRP-users]

I got it by running: uhd_images_downloader -t sdk -t n3xx
 
based on instructions here: 
https://files.ettus.com/manual/page_usrp_n3xx.html#n3xx_software_dev_sdk
 
It does not appear to have gnuradio installed
 
OK, gnuradio seems to build fine for cross-compile, it is when I get to the 
gr-ettus step which is next (needed for RFNoC).  I haven't tried running 
gnuradio, but it builds.

 Where did you get the toolchain? Does the N310 have gnuradio installed?
 Feels like the sdk may not have the packages you need to build gnuradio
 installed.
 
 Try disabling qt4 and seeing if you can get gnuradio to build like that
 as a test.

Where did you get the toolchain? Does the N310 have gnuradio installed?
Feels like the sdk may not have the packages you need to build gnuradio
installed.

Try disabling qt4 and seeing if you can get gnuradio to build like that
as a test.

Re: [USRP-users] cross-compiling for N310

[Jason Matusiak via USRP-users]

It looks like qt4 was not included in the cross-compile build.  If I look at my 
working e300 cross-compile, I have a folder: 
/opt/gnuradio/e300/sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/include/qt4/
 
(in fact, there is a tone of stuff in that include).
 
If I look in the N310 directory, it doesn't exist: 
/opt/gnuradio/N310/sysroots/armv7ahf-neon-oe-linux-gnueabi/usr/include/
 
(and there are very few files/folders in there at all.
 
I will look into building it by hand, but I am guessing that it will just lead 
to more things needing to be cross-compiled

 Has anyone successfully created a new build for an N310 (RFNoC version in 
particular)?  I was going to bring it up to date, but seem to be having issues.
 
I ran: uhd_images_downloader -t sdimg -v
To get the *.sh image for cross-compiling: 
oecore-x86_64-cortexa9hf-neon-toolchain-nodistro.0.sh
 
I then install it like I do for the E310.
 
I create a src directory and pull down uhd and its sub-module fpga-src.  I've 
tried main, master, and UHD-3.13, and they all build fine, but give me issues 
later on.  In my cmake I make sure to have -DENABLE_RFNOC=ON and I see it 
checked when I run cmake-gui.
 
I then pull down gnuradio, and build like I normally do.
 
Lastly, I pull down gr-ettus.  When I run: cmake 
-DCMAKE_TOOLCHAIN_FILE=$PREFIX/src/gnuradio/cmake/Toolchains/oe-sdk_cross.cmake 
-DENABLE_DOXYGEN=OFF -DCMAKE_INSTALL_PREFIX=/usr ..
 
It mostly works and then errors out with:
 
-- Found PkgConfig: 
/opt/gnuradio/N310/sysroots/x86_64-oesdk-linux/usr/bin/pkg-config (found 
version "0.29.2")

 In the past, I thought that that usually means uhd was not built properly to 
have RFNoC enabled, but it looks to me like it is here.
 Anyone happen to see what I am missing here?

Re: [USRP-users] cross-compiling for N310

[Jason Matusiak via USRP-users]

OK, I see the first mistake.  I was copying-and-pasting my notes for the E310 
which had a different sysroot.  Once I made the change to the proper one, it 
seems like it got past the rfnoc issue (or I haven't hit it yet with this new 
error).
 
I am not getting:
- Found PkgConfig: 
/opt/gnuradio/N310/sysroots/x86_64-oesdk-linux/usr/bin/pkg-config (found 
version "0.29.2")
