busybox 更改后无法成功构建（添加了 i2cdetect 和 i2ctransfer）

Question

设置：

虚拟盒7.0 镜像 Ubuntu 22.04.1

目标：

在 busybox 中添加 i2cdetect 后，根据 Digi-Key 教程在 yocto 项目中重建 STM32MP157 的 Linux 映像

问题：

我猜主要原因是

Exception: FileExistsError: [Errno 17] File exists: '/bin/busybox.suid' -> '/home/vboxuser/Projects/yocto/build-mp1/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/busybox/1.36.1-r0/package/usr/lib/busybox/ptest/bin/i2cdetect'

在

bitbake -c do_cleanall busybox

和

bitbake -c do_cleanall custom_image

之后，我能够成功构建图像，但没有i2cDetect 模块

似乎添加 i2ctransfer 代替 i2cdetect 会导致同样的问题

我注意到有人已经在 dunfell 分支中用

busybox-1.35.0-r0

遇到了这个 问题，但我的

meta/recipes-core/busybox/busybox.inc

文件已经有这个补丁。

Answer 1

我已经在

this

答案中提供了有关如何准备 Busybox 配置片段的答案。

除此之外，请确保不要同时包含

busybox

解决方案和

i2c-tools

配方，因为这会因文件冲突而失败。
