Add aarch64/arm64 shared libs

[pquimby]

Please build shared libraries for 64b ARM platforms. This will add to the range of mobile computers that can be used with the onboard SDK and increase the computational resources available to users.

[longlong2010]

You may try to use so/XU3/ibDJI_guidance.so. It works for Raspberry PI 3 Model B.

[JJJJJJJack]

I think XU3 is Armv7 and boards come after that, like the C2, is Armv8 and the library provided is not compatible.

[tangketan]

@pquimby Would you please provide the exact compiler? We can try building the library with specified compiler.

[JJJJJJJack]

Hi Tangketan,

Thanks for the reply. The compiler I'm using on the Odroid C2 is as follow:

odroid@odroid64:~$ gcc -v Using built-in specs. COLLECT_GCC=gcc COLLECT_LTO_WRAPPER=/usr/lib/gcc/aarch64-linux-gnu/5/lto-wrapper Target: aarch64-linux-gnu Configured with: ../src/configure -v --with-pkgversion='Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.1' --with-bugurl=file:///usr/share/doc/gcc-5/README.Bugs --enable-languages=c,ada,c++,java,go,d,fortran,objc,obj-c++ --prefix=/usr --program-suffix=-5 --enable-shared --enable-linker-build-id --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --libdir=/usr/lib --enable-nls --with-sysroot=/ --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --with-default-libstdcxx-abi=new --enable-gnu-unique-object --disable-libquadmath --enable-plugin --with-system-zlib --disable-browser-plugin --enable-java-awt=gtk --enable-gtk-cairo --with-java-home=/usr/lib/jvm/java-1.5.0-gcj-5-arm64/jre --enable-java-home --with-jvm-root-dir=/usr/lib/jvm/java-1.5.0-gcj-5-arm64 --with-jvm-jar-dir=/usr/lib/jvm-exports/java-1.5.0-gcj-5-arm64 --with-arch-directory=aarch64 --with-ecj-jar=/usr/share/java/eclipse-ecj.jar --enable-multiarch --enable-fix-cortex-a53-843419 --disable-werror --enable-checking=release --build=aarch64-linux-gnu --host=aarch64-linux-gnu --target=aarch64-linux-gnu Thread model: posix gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.1)

I just update a so file compiled on 64-bit TX1. Yet the Ubuntu is 14.04. See if you can use that so file.

it seems there is no enough memory left. Could you try make -j1 ?

Can a shared library be built for 64b ARM platforms, specifically the NVidia TX1 with Ubuntu 16.04? I tried the TX1, arm, and xu3 ones available but it did not work. Thanks!

What parameters effect pitch of aircraft in the air. Inside flyc_param 800+ parameters, which ones directly effect tilt of aircraft in the air

The so library file under so/tx1/ is not working on nvidia tx1, ubuntu 64.

[TheRobotStudio]

@tangketan Hello, I'm also interested to run the SDK on a 64bits Jetson TX2. Would it be possible to build and add the so library for aarch64 TX2 ? That would be great !

[saurabh984]

What's the point of Open Sourcing something which you don't really support! Could you please update the libraries?

[lanyusea]

sorry :(

any updates of the libdji_guidance.so library file for Jetson Tx2 arm architecture. please let me know,

Thanks

[saurabh984]

@lanyusea Can you please recompile and upload the new libdji_guidance.so?

[TheRobotStudio]

Any update on this topic ? Thanks!

[samsdolphin]

Dose any of you find the compatible library for the Jetson TX2? Thanks!
