YOCTO - 第一次为 BBB 构建答案

【问题描述】：

我第一次尝试为我的 BeagleBoneBlack 使用 Yocto 工具。

首先我运行这个 bash 文件来安装 Yocto：

#!/bin/bash
WKDIR=/work
mkdir -p $WKDIR/beaglebone-black/yocto/sources
mkdir -p $WKDIR/beaglebone-black/yocto/builds
cd $WKDIR/beaglebone-black/yocto/sources
git clone -b morty git://git.yoctoproject.org/poky.git poky-morty
cd $WKDIR/beaglebone-black/yocto/
source sources/poky-morty/oe-init-build-env builds/build-bbb-morty

然后我在“build-bbb-morty/conf”目录中编辑了文件local.conf：

MACHINE ?= "beaglebone"

并添加了

DL_DIR ?= "${TOPDIR}/../dl"
IMAGE_INSTALL_append = " kernel-modules kernel-devicetree"

然后我运行 bitbake:> bitbake core-image-minimal

在我的 Core i7 五代大约 8 小时后，我在终端输出中得到了这个结果，但我不知道我需要做什么来修复它：

bitbake core-image-minimal

【解决方案1】：

虽然不确定这可能是问题的原因，但在 local.conf 上下文中将包添加到映像的首选方法是使用 CORE_IMAGE_EXTRA_INSTALL 变量。

因此改变：

IMAGE_INSTALL_append = "内核模块内核设备树"

到

CORE_IMAGE_EXTRA_INSTALL += "kernel-modules kernel-devicetree"

【解决方案2】：

我认为你的工作方法没有问题。好像是构建环境的问题，但是错误日志好像证实了。您的日志位置位于“/work/beaglebone-black/yocto/builds/build-bbb-morty/tmp/work/beaglebone-poky-linux-gnueabi/core-image-minimal/1.0-r0/temp/log.do_image_wic。 23788"

【解决方案3】：

您的错误日志表明获取二进制文件的 URL 失败。

您可以尝试通过代理使用隧道。或者您可以再次运行 bitbake，因为它有时也会由于网络状况而失败。
