本来想采用树莓派进行，发现不行
配置Linux编译开发环境
修改bash
pi@raspberrypi:/bin $ mv sh sh.bak
mv: cannot move 'sh' to 'sh.bak': Permission denied
pi@raspberrypi:/bin $ sudo mv sh sh.bak
pi@raspberrypi:/bin $ sudo ln -s /bin/bash /bin/sh
pi@raspberrypi:/bin $ ls
bash chgrp dumpkeys hciconfig login mv ntfsfix ps ss tar zcmp
bunzip2 chmod echo hostname loginctl nano ntfsinfo pwd stty tempfile zdiff
busybox chown ed ip lowntfs-3g nc ntfsls rbash su touch zegrep
bzcat chvt egrep journalctl ls nc.openbsd ntfsmove readlink sync true zfgrep
bzcmp con2fbmap false kbd_mode lsblk nc.traditional ntfsrecover red systemctl udevadm zforce

pi@raspberrypi:/bin $ ls -l sh
lrwxrwxrwx 1 root root 9 Dec 22 08:51 sh -> /bin/bash
安装Python环境
pi@raspberrypi:/ $ sudo pip3 install pycryptodome
pi@raspberrypi:/ $ sudo pip3 install kconfiglib
pi@raspberrypi:/ $ sudo pip3 install six --upgrade --ignore-installed six
pi@raspberrypi:/ $ sudo pip3 install ecdsa
将Python3作为默认版本
pi@raspberrypi:/usr/bin $ sudo mv python python.bak
pi@raspberrypi:/usr/bin $ sudo ln -s python3.7
python3.7 python3.7-config python3.7m python3.7m-config
pi@raspberrypi:/usr/bin $ sudo ln -s python3.7 /usr/bin/python
pi@raspberrypi:/usr/bin $ ls -l python
lrwxrwxrwx 1 root root 9 Dec 23 08:31 python -> python3.7
pi@raspberrypi:/usr/bin $ python -V
Python 3.7.3
安装SCons环境
pi@raspberrypi:/usr/bin $ sudo apt-get install scons -y
pi@raspberrypi:/usr/bin $ scons -v
更改为3.0.4版本
https://scons.org/pages/download.html
pi@raspberrypi:/opt/scons/SCons-4.0.1 $ sudo tar -xvf scons-4.0.1.tar.gz
pi@raspberrypi:/opt/scons/SCons-4.0.1 $ cd SCons-4.0.1/
pi@raspberrypi:/opt/scons/SCons-4.0.1 $ sudo python3 setup.py install
pi@raspberrypi:/opt/scons/SCons-4.0.1 $ scons -v
SCons by Steven Knight et al.:
SCons: v4.0.1.
安装编译工具
gn工具——产生ninja编译脚本
pi@raspberrypi:~ $ sudo tar xvf ./gn.1523.tar -C ~/
ninja工具——执行ninja编译脚本
pi@raspberrypi:~ $ sudo tar xvf ./ninja.1.9.0.tar -C ~/
交叉编译器gcc_riscv32
pi@raspberrypi:~ $ sudo tar xvf gcc_riscv32-linux-7.3.0.tar.gz -C ~/
配置环境变量
pi@raspberrypi:~ $ vim ~/.bashrc
export PATH=~/gn:$PATH
export PATH=~/ninja:$PATH
export PATH=~/gcc_riscv32/bin:$PATH
生效配置：
pi@raspberrypi:~ $ source ~/.bashrc
pi@raspberrypi:~ $ riscv32-unknown-elf-gcc -v
-bash: /home/pi/gcc_riscv32/bin/riscv32-unknown-elf-gcc: cannot execute binary file: Exec format error
由于树莓派不是X86架构，而是ARM架构，目前gcc_riscv32不支持。。。。
改为X86服务器即可：
(bearpi) 15:53 luohb@Studynode:~/tools
$ riscv32-unknown-elf-gcc -v
