我尝试为我的主板制作自定义BSP（自定义beaglebone）。 这是我第一次和yocto在一起。我阅读了很多文档和教程。但我无法解决我的问题。
当我对任务yocto-bsp出现问题时，我一直在使用do_kernel_metadata。
创建自定义BSP
$> yocto-bsp create biatime arm
> 4.12
> standard/beaglebone
> tune for cortex8
> smp yes
> xorg no
> keyboard yes
> screen no
配置bblayer以获取__meta-biatime __
# POKY_BBLAYERS_CONF_VERSION is increased each time
build/conf/bblayers.conf
# changes incompatibly

自脚本生成器开始以来，注意已在meta-biatime上发生了变化。
你能解释一下我心中的问题吗？
感谢您的支持。
