How to build and test AI on SB52¶
Please follow the below steps to complete AI simple test.
(1)Download the test APP package linux_sample_2019_10_25_UTC.rar from
https://onlinedcc.innocomm.com/seeddms/out/out.ViewFolder.php?folderid=1464&showtree=1
(2)Extract linux_sample_2019_10_25_UTC.rar you will have folder named linux_example
(3)After fully built SB50 Yocto linux, we'll export toolchain path as below:
This is my compile environment for your reference:export PATH=/home/inncomm/root/sb50/build/tmp/work/aarch64-poky-linux/apunn/1.0-r0/recipe-sysroot-native/usr/bin/aarch64-poky-linux/:$PATH export SDKTARGETSYSROOT="//home/inncomm/root/sb50/build/tmp/work/aarch64-poky-linux/apunn/1.0-r0/recipe-sysroot" export OECORE_NATIVE_SYSROOT="/home/inncomm/root/sb50/build/tmp/work/aarch64-poky-linux/apunn/1.0-r0/recipe-sysroot-native" export CXX="aarch64-poky-linux-clang++ --sysroot=$SDKTARGETSYSROOT" export CC="aarch64-poky-linux-clang --sysroot=$SDKTARGETSYSROOT"
(4)make makefile under linux_example
(a) Modify linux_example/CMakeLists.txt
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
(b) If you meet lack of libcxx.so
Please add extract and copy the attached lib_1.rar to linux_example/
And add the below to linux_example/CMakeLists.txt
LINK_LIBRARIES("${CMAKE_CURRENT_LIST_DIR}/lib_1/aarch64-poky-linux/libc++.so.1")
LINK_LIBRARIES("${CMAKE_CURRENT_LIST_DIR}/lib_1/aarch64-poky-linux/libc++abi.so.1")
(c)Move to /linux_example
inncomm@inncomm-Dell-System-XPS-L502X:~/yocto/SB50/linux_sample$ mkdir build
inncomm@inncomm-Dell-System-XPS-L502X:~/yocto/SB50/linux_sample$ cd build
