RISC-V P Extension v0.5.2

Toolchain

Suggested Version: v5_1_1

nds-gnu-toolchain

Prebuilt Releases: Andes-Development-Kit

./build_linux_toolchain.sh

TARGET=riscv64-linux
PREFIX=/opt/andes
ARCH=rv64imafdcxandes
ABI=lp64d
CPU=andes-25-series
XLEN=64
BUILD=`pwd`/build-nds64le-linux-glibc-v5d

Qemu

qemu

shell ./build

../configure --prefix=/opt/andes --target-list=riscv32-linux-user,riscv64-linux-user --disable-werror --static

Board

Use the installed toolchain's sysroot, or the prebuilt releases above.

/etc/ld.so.conf

include /etc/ld.so.conf.d/*.conf
/path/to/the/sysroot/library

shell

ldconfig -v

Then the sysroot library should appear in the result.

OpenCV Test

OpenCV

shell ./build

cmake -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=/opt/andes -D BUILD_SHARED_LIBS=OFF -D CMAKE_TOOLCHAIN_FILE=../platforms/linux/riscv64-andes-gcc.toolchain.cmake ..

Test Tips

dnn module test

shell ./build/bin

qemu-riscv64 -cpu andes-ax25 -L /opt/andes/sysroot opencv_test_dnn
# int8layers/layers_common_simd.hpp
# --gtest_filter=*Int8*
# --gtest_filter=*Conv*
# --gtest_filter=*Gemm*

imgproc module test

shell ./build/bin

qemu-riscv64 -cpu andes-ax25 -L /opt/andes/sysroot opencv_test_imgproc
# imgwarp.rvp.cpp
# --gtest_filter=*Affine*
#
# resize.rvp.cpp
# --gtest_filter=*Resize*
#
# sumpixels.simd.hpp
# --gtest_filter=*Integ*

features2d module test

shell ./build/bin

qemu-riscv64 -cpu andes-ax25 -L /opt/andes/sysroot opencv_test_features2d
# fast.rvp.cpp
# --gtest_filter=*FAST*
# --gtest_filter=*ORB*
