I have searched a lot and still could not find the necessary documentation to compile the vx_delegate for the A311D on linux.

To verify, these are the commands I used to build the delegate.

cmake .. -DCONFIG=A311D -DEXTERNAL_VIV_SDK=$(pwd)/aarch64_A311D_6.4.8/include

Could someone provide details on how to compile for the A311D ? All I see are mixed experiences of some unable to build and others able to build it without any step by step instructions.

Thank you in advance!

@ZephyrLabs ,

Please try to build & install TIM-VX firstly, then build vx-delegate with cmake -DTIM_VX_INSTALL=

Thanks

Please try to build & install TIM-VX firstly, then build vx-delegate with cmake -DTIM_VX_INSTALL=

Thanks

@sunshinemyson I built TIM-VX with the right configuration for A311D and it successfully was built however back to building vx_delegate with cmake -DTIM_VX_INSTALL= pointing to the right directory ,

[100%] Linking CXX shared library libvx_delegate.so
/usr/bin/ld: /home/zephyr/Documents/npu/tflite_vx/tim-vx/build/install/lib/libtim-vx.so: error adding symbols: file in wrong format
collect2: error: ld returned 1 exit status

make[1]: *** [CMakeFiles/Makefile2:1276: CMakeFiles/vx_delegate.dir/rule] Error 2
make: *** [Makefile:169: vx_delegate] Error 2

It seems It's using the wrong linker, is there any additional configuration missing, perhaps relating to the toolchain directory ?

Hello @sunshinemyson could you provide any guidance towards this issue ?

I've solved this issue by just making the necessary changes to cross compile.
I will share what I did for anyone trying to build the vx_delegate for the A311D or S905D3.

Cloning repo

Follow the official instructions to first download TIM-VX and TFLite VX delegate repositories.

mkdir wksp && cd wksp
# tim-vx is optional, it will be downloaded by CMake automatically for none-cross build
# if you want to do cross build with cmake, you have to build tim-vx firstly
git clone https://github.com/VeriSilicon/TIM-VX.git tim-vx
git clone https://github.com/VeriSilicon/tflite-vx-delegate.git

Build TIM-VX

Build the necessary Binaries TIM-VX, the -DCONFIG will change based on the SoC.

cd tim-vx
mkdir build && cd build

If you plan on building for the

  • A311D -> run the cmake configuration cmake .. -DCONFIG=A311D
  • S905D3 -> run the cmake configuration cmake .. -DCONFIG=S905D3

after the configuration, run make -j4 and make install to build TIM-VX appropriately. The prepared TIM-VX install location is in wksp/tim-vx/build/install/

Also you need to make sure you have the cross compiler in an appropriate location, so that the next steps can have access to it. here we will copy the cross compiler to /opt
run cp gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu -r /opt/


Build Tflite-vx-delegate

Configure cross compiling

Now proceed to build the vx delegate, say you are in the wksp/tim-vx/build, you will need to navigate to the tflite vx delegate directory with

cd ../../tflite-vx-delegate

Here is where you make the crucial changes to enable cross compiling. Copy this patch into a cross_compile.patch file in tflite-vx-delegate folder and git apply cross_compile.patch

+set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
+set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)
+
+add_definitions(-mtune=cortex-a53)

Note that this patch depends on the cross compiler being in /opt/

For the S905D3 alone, you will need to remove the add_definitions(-mtune=cortex-a53) line as it uses A55 cpu cores

Cross compile

now you can cross compile the delegate easily with the rest of the steps,
remember to use the right path to the installed tim-vx, ie wksp/tim-vx/build/install/

mkdir build && cd build
cmake .. -DTIM_VX_INSTALL=../../tim-vx/build/install/
make vx_delegate -j4

The libvx_delegate.so file should be present in the build folder you are in.

Enjoy.

@ZephyrLabs ,

Thanks for the proposal, we will try to make a formal solution.

Hello @sunshinemyson it seems there is a new issue

cc1: error: invalid feature modifier in ‘-march=armv8.2-a+bf16’
make[2]: *** [_deps/xnnpack-build/CMakeFiles/all_microkernels.dir/build.make:40242: _deps/xnnpack-build/CMakeFiles/all_microkernels.dir/src/bf16-gemm/gen/1x4c8-minmax-neonbf16-bfdot.c.o] Error 1
make[2]: *** Waiting for unfinished jobs..

Is there a newer cross-compiler which is recommended to use which supports this ?

Sorry for late reply. You need to ask your SoC for latest toolchain files. Besides that, A311D and S905D3 are two different chips, what toolchain to used is determined by chip manufacturers ,thanks.

HI @chenfeiyue-cfy , sorry there must be confusion, I am not able to build tflite-vx-delegate with default steps and the toolchain specified by yourself. can you verify if it works on your side ?

Regards.

Here are some notes:

  1. The toolchain is not provided by us, we only received it from the manufacturer. It was generated by SoC vendor.
  2. Looks like you met build issue in XNNPack building, try disabling xnnpack build with -DTFLITE_ENABLE_XNNPACK=OFF and perhaps you will compile sucessfully.
  3. If it still not works, pelase Do Not set "-march=armv8.2-a+bf16"
    Thanks!

@chenfeiyue-cfy @ZephyrLabs ,

"-march=armv8.2-a+bf16" this is depends on your toolchains version. I have such failure before because given "arch" is not compatible with toolchain compiler version.

@ZephyrLabs , Please try @chenfeiyue-cfy 's suggestion.

Thanks
