Cross-Compile ArmNN on x86_64 for arm64

fatimak over 6 years ago

Hi ,

I am looking for someway of using the armNN SDK on a Xilinx Zynq Platform which has Quad-core ARM® CortexTM-A53 MPCoreTM up to 1.5GHz and an ARM MALI 400 MP2 GPU. With ARM Mali GPU noted off in a previous question my next task is to look into if it is possible to run the SDK on the Cortex processor but lloking at the guides I would only be able to cross compile it. So my first question is that is it possible to run it on the ARM A53 on the Zynq Platform and also if tensorflow would run on it as well.

Regards

Fatima

Hi Fatima, Please have a look at the Arm github area: https://github.com/ARM-software/Tool-Solutions The script to cross-compile is in: https://github.com/ARM-software/Tool-Solutions/tree/master/ml...

Hi,

I am cross-compiling x86 for arm-v8a

while doing cmake command it shows that it cannot find caffe.pb.cc file but while going through the path for caffe which i provided in cmake command it is visible in the file-system

about the setup ; the command i followed

0.Prerequisites
   sudo apt-get install git
   sudo apt-get install scons
   sudo apt-get install gcc-arm-linux-gnueabihf
   sudo apt-get install g++-arm-linux-gnueabihf
   sudo apt-get install curl
   sudo apt-get install autoconf
   sudo apt-get install libtool
   sudo apt-get install cmake

1.Downloaded the repositry and bundles
   git clone github.com/.../ComputeLibrary.git
