1.芯片解密 libncursesw.so.5: cannot open shared object file
芯片解密首先是会有这样的错误输出

/opt/gcc-arm/gcc-arm-11.2-2022.02-x86_64-arm-none-eabi/bin/arm-none-eabi-gdb -q --interpreter=mi2
/opt/gcc-arm/gcc-arm-11.2-2022.02-x86_64-arm-none-eabi/bin/arm-none-eabi-gdb: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory
观察ldd可以看到缺少两个so: libncursesw.so.5, libpython3.6m.so.1.0

ldd /opt/gcc-arm/gcc-arm-11.2-2022.02-x86_64-arm-none-eabi/bin/arm-none-eabi-gdb

libncursesw.so.5可以通过安装 libncursesw5 可以解决

sudo apt install libncursesw5

2. libpython3.6m.so.1.0: cannot open shared object file

这样就剩下另一个动态连接库无法找到

/opt/gcc-arm/gcc-arm-11.2-2022.02-x86_64-arm-none-eabi/bin/arm-none-eabi-gdb -q --interpreter=mi2
/opt/gcc-arm/gcc-arm-11.2-2022.02-x86_64-arm-none-eabi/bin/arm-none-eabi-gdb: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory

但是 Ubuntu20.04 自带的 Python3.8, 无法安装 Python3.6

~$ sudo apt-get install libpython3.6

简单粗暴的解决方法就是直接用3.8的代替

cd /usr/lib/x86_64-linux-gnu/
$ ll libpython*
lrwxrwxrwx 1 root root      19 Jul  1 20:27 libpython2.7.so.1 -> libpython2.7.so.1.0
-rw-r--r-- 1 root root 3455600 Jul  1 20:27 libpython2.7.so.1.0
lrwxrwxrwx 1 root root      55 Jun 23 04:18 libpython3.8.a -> ../python3.8/config-3.8-x86_64-linux-gnu/libpython3.8.a
lrwxrwxrwx 1 root root      17 Jun 23 04:18 libpython3.8.so -> libpython3.8.so.1
lrwxrwxrwx 1 root root      19 Jun 23 04:18 libpython3.8.so.1 -> libpython3.8.so.1.0
-rw-r--r-- 1 root root 5449112 Jun 23 04:18 libpython3.8.so.1.0
$ sudo ln -s libpython3.8.so.1.0 libpython3.6m.so.1.0

这时候再运行就可以启动了
