chipyard的toolchain安装出错1

chipyard安装步骤见官网

https://chipyard.readthedocs.io/en/latest/Simulation/Software-RTL-Simulation.html#synopsys-vcs-license-required

我是在执行这条命令时出了错：

./scripts/build-toolchains.sh riscv-tools # for a normal risc-v toolchain

 错误见图：unable to access 'https://boringssl.googlesource.com/boringssl/' : Failed to connect to boringssl.googlesource.com Port443:Connection timed out.

解决方法如下：在qemu/roms/edk2/CryptoPkg/Library/OpensslLib/openssl路径下找到.gitmodules，将其中“boringssl”的url从https://boringssl.googlesource.com/boringssl 改到

https://github.com/google/boringssl.git

之后在当前路径下输入命令：

git submodule sync

再返回执行原命令。

好起来了！
