NVDLA virtual platform 环境搭建

作者：互联网

官方链接 http://nvdla.org/vp.html 

 

下载VP源码

# sudo apt-get install git //先安装git

$ git clone https://github.com/nvdla/vp.git 

$ cd vp  

$ git submodule update --init --recursive  //更新子模块文件

 

安装依赖

$ sudo apt-get update $ sudo apt-get install g++ cmake libboost-dev python-dev libglib2.0-dev libpixman-1-dev liblua5.2-dev swig libcap-dev libattr1-d

 

安装systemC

注意：需要指定systemc2.3.0版本，更高版本存在不兼容

$ wget -O systemc-2.3.0a.tar.gz https://www.accellera.org/images/downloads/standards/systemc/systemc-2.3.0a.tar.gz

//使用https链接，http无法访问 $ tar -xzvf systemc-2.3.0a.tar.gz $ cd systemc-2.3.0a $ sudo mkdir -p /usr/local/systemc-2.3.0/ $ mkdir objdir $ cd objdir $ ../configure --prefix=/usr/local/systemc-2.3.0 $ make $ sudo make install

 

安装perl package (YML 与 Tee)

$ wget -O YAML-1.24.tar.gz https://search.cpan.org/CPAN/authors/id/T/TI/TINITA/YAML-1.24.tar.gz

$ tar -xzvf YAML-1.24.tar.gz $ cd YAML-1.24 $ perl Makefile.PL

$ make

$ sudo make install

$ wget -O IO-Tee-0.65.tar.gz https://search.cpan.org/CPAN/authors/id/N/NE/NEILB/IO-Tee-0.65.tar.gz

$ tar -xzvf IO-Tee-0.65.tar.gz $ cd IO-Tee-0.65

$ perl Makefile.PL

$ make

$ sudo make install

 

构建NVDLA CMOD

$ git clone https://github.com/nvdla/hw.git

$ cd hw

$ make

 

make时候初出现如下提示，需要指定构造环境的路径

依赖的环境如下

可以在make之前修改MakeFile文件中的default路径，cpp等路径可以用 whereis cpp查找，一般路径为/ust/bin/cpp

 

$ tools/bin/tmake -build cmod_top

构造成功如下

生成的文件的在目录 hw/outdir/<project>/cmod/release. 下

 

构建和安装仿真器

# cd vp //切换到vp仓库

$ cmake -DCMAKE_INSTALL_PREFIX=build -DSYSTEMC_PREFIX=/usr/local/systemc-2.3.0/ -DNVDLA_HW_PREFIX=/home/sunqiliang/VP/hw -DNVDLA_HW_PROJECT=sun_test

 

//DCMAKE_INSTALL_PREFIX仿真器的安装路径 systemc prefix 是已安装systemc的路径 nvdla_hw prefix是NVDLA HW仓库路径 nvdla_hw project是HW工程名字,上个步骤中project名称为sun_test

运行成功如下

 

# sudo apt-get install flex //make时候会用到

# sudo apt-get install bison //make时候会用到

 

$ make

$ make install

 

将子目录下CMakeList.txt中的 CMAKE_CXX_FLAGS语句中的-Werror删除（ 只打印warn 不进行错误处理）

vp/CMakeLists.txt

vp/models/nvdla/CMakeLists.txt

vp/fpga/aws-fpga/fpga_sc_wrapper/CMakeLists.txt

vp/aws-fpga/cosim_sc_wrapper/CMakeLists.txt

 

参考 Ubuntu16.04 NVDLA环境搭建 https://www.codetd.com/article/2925855

 

运行成功如下

 

 

交叉编译一个linux内核

wget https://buildroot.org/downloads/buildroot-2017.11.tar.gz

tar -zxvf buildroot-2017.11.tar.gz

cd buildroot-2017.11/

 

 sudo apt-get install libncurses5-dev // make menuconfig时会用到

 

$ make qemu_aarch64_virt_defconfig

$ make menuconfig

* Target Options -> Target Architecture -> AArch64 (little endian) * Target Options -> Target Architecture Variant -> cortex-A57 * Toolchain -> Custom kernel headers series -> 4.13.x * Toolchain -> Toolchain type -> External toolchain * Toolchain -> Toolchain -> Linaro AArch64 2017.08 * Toolchain -> Toolchain origin -> Toolchain to be downloaded and installed * Kernel -> () Kernel version -> 4.13.3 * Kernel -> Kernel configuration -> Use the architecture default configuration * System configuration -> Enable root login with password -> Y * System configuration -> Root password -> nvdla * Target Packages -> Show packages that are also provided by busybox -> Y * Target Packages -> Networking applications -> openssh -> Y

$ make -j4// 编译时间较长，建议先做其他事情

 

运行完成如下

 

 

运行虚拟机

$ export SC_SIGNAL_WRITE_CHECK=DISABLE

# vim conf/aarch64_nvdla.lua

//dirver file修改为上面生成的kenel路径 /home/sunqiliang/VP/buildroot-2017.11/output/images/rootfs.ext4

//-kenerl 路径修改为/home/sunqiliang/VP/buildroot-2017.11/output/images/Images

$ ./build/bin/aarch64_toplevel -c conf/aarch64_nvdla.lua

 

运行成功如下

输入之前make menuconfig设置的登录密码

 

运行test

# mount -t 9p -o trans=virtio r /mnt # cd /mnt/tests/hello # ./aarch64_hello

 

运行成功如下

 

退出命令虚拟机 ‘ctrl+a x’
