一般故障排除

cargo-embed问题

大多数cargo-embed问题要么与未正确安装udev规则（在Linux上）有关，要么与在嵌入中选择了错误的芯片配置有关。 Embed.toml确保你两个都是对的。

如果上述方法不适用于您，您可以在discovery issue tracker打开问题。 或者，您也可以访问Rust Embedded matrix channel或者probe-rs matrix channel并在那里寻求帮助。

原因

您忘记为微控制器安装正确的目标(对于v2，thumbv7em-none-eabihf，对于v1thumbv6m-none-eabi)。

$ rustup target add thumbv7em-none-eabihf

# micro:bit v1
$ rustup target add thumbv6m-none-eabi
