raspberry pi u-boot 中使用 yocto 的额外命令
Extra commands in raspberry pi u-boot using yocto
我想使用 yocto 在 raspberry pi u-boot 中添加自定义命令
我可以按照此处提供的答案使用 make 添加自定义
现在我想在 raspberry pi 中使用 yocto 添加它。
但首先我只想在 u-boot 中添加定时器命令，它存在于 u-boot 源代码的 misc.c 中，我们只需要在 defconfig 文件
中添加 CONFIG_CMD_TIMER=y
到目前为止我尝试了以下设置
- 克隆的 poky
- 克隆的 meta-raspberrypi
- 在 local.conf
中启用了 u-boot 和 uart
- 创建了一个自定义层（在
bblayers.conf中添加了自定义层）以添加命令配置
自定义图层中的配方详情
- 创建以下目录结构
meta-custom-layer/recipes-bsp/u-boot/
- 创建了一个包含以下内容的
.bbappend 文件
$ cat meta-custom-layer/recipes-bsp/u-boot/u-boot_%.bbappend
FILESEXTRAPATHS_prepend := "${THISDIR}:"
SRC_URI += " file://rpi_3_defconfig.patch;patchdir=${S}/configs "
meta-custom-layer/recipes-bsp/u-boot/
$ ls -l meta-custom-layer/recipes-bsp/u-boot/
