I follow the radxa wiki page to download the android 8.1 source code, but when I sync the code after I have initialed the environment and downloaded the repo, it still has errors. More specifically, the errors are can not access the tsinghua mirror website. So is there anyone can give me some ideas?(I put the error below)
fatal: unable to access ‘https://aosp.tuna.tsinghua.edu.cn/device/google/accessory/demokit/’: gnutls_handshake() failed: The TLS connection was non-properly terminated.
