TB-RK3399ProD_V1.5固件源码同步出错

error: Cannot fetch packages-apps-Settings from https://github.com/rockchip-toybrick/packages-apps-Settings
error: RPC failed; curl 56 GnuTLS recv error (-54): Error in the pull function.
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: unpack-objects failed

为什么同步到kernel和settings老是出错？是不是需要什么权限？
