具体错误信息如下:

Summary: There were 2 ERROR messages, returning a non-zero exit code.

构建失败的原因是 linux-firmware-rpidistro-bcm43456 软件包的许可证 synaptics-killswitch 未被 Yocto 接受。以下是具体解决方案和步骤：

错误核心信息显示：

Has a restricted license 'synaptics-killswitch' which is not listed in your LICENSE_FLAGS_ACCEPTED

原因：Yocto 默认会阻止带有特殊许可证（如专利或商业限制）的软件包，需手动将其加入白名单。

解决方法：
修改 conf/local.conf 文件，添加以下配置：

LICENSE_FLAGS_ACCEPTED += "synaptics-killswitch"

如果存在其他受限许可证（如 commercial），可一并添加：

LICENSE_FLAGS_ACCEPTED = "synaptics-killswitch commercial"
