PULP（pulp-sdk） ubuntu18.04环境搭建
PULP = Parallel Ultra Low Power
第一个坑：切换为python为默认的python3
我这里简单粗暴的直接创建软链接 python3.6 到python
重要参考文档：NBruschi_gvsoc_tutorial_part1.pdf
第二个坑，github，不是墙的问题，当然可以解决问题，可以参考我的配置
1. 修改.ssh/config为如下：
root@ubuntu:/opt# cat ~/.ssh/
config id_rsa id_rsa.pub known_hosts
root@ubuntu:/opt# cat ~/.ssh/config
Host github.com
HostName ssh.github.com #
User git
Port 443
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
2. 在/etc/hosts中添加github.com的域名解析
root@ubuntu:/opt# cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 ubuntu
20.205.243.166 github.com
修改完成后，代码下载飞快，否则，估计很多人第一步代码下载就会卡上好几天。
编译toolchain
$sudo apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev
$git clone https://github.com/pulp-platform/pulp-riscv-gnu-toolchain
$git submodule update --init --recursive
$rm -rf riscv-dejagnu/
qiao@ubuntu:~/riscv/pulp-riscv-gnu-toolchain$ git clone https://gitee.com/mirrors/riscv-dejagnu
$rm -rf riscv-newlib
$git clone https://gitee.com/mirrors/riscv-newlib
$./configure --prefix=/opt/pulp-riscv-gnu-toolchain --with-arch=rv32imc --with-cmodel=medlow --enable-multilib
$make编译完成后，查看/opt/pulp-riscv-gnu-toolchain.
编译pulp-sdk
sudo apt-get install -y build-essential git libftdi-dev libftdi1 doxygen python3-pip
libsdl2-dev curl cmake libusb-1.0-0-dev scons gtkwave libsndfile1-dev rsync autoconf
automake texinfo libtool pkg-config libsdl2-ttf-dev
pip install argcomplete pyelftools sixTo install the PULP-SDK follow these steps:
$ git clone https://github.com/pulp-platform/pulp-sdk
$ export PULP_RISCV_GCC_TOOLCHAIN=
$ cd pulp-sdk
$ source configs/pulp-open.sh
$ make build
