Question

我正试图从官方存储库https://github.com/beagleboard/linux

为beaglebone black构建Linux

我能够获取并运行menuconfig，但是当我尝试编译内核时，我得到了错误。

以下是配方文件的内容。

文件名：linux-yocto-chipsee_3.14.bb
路径：/ home / ankur / yocto_daisy / poky / meta-ybdevelop / recipes-example / linux

inherit kernel
require recipes-kernel/linux/linux-yocto.inc

BRANCH = "3.14"
# Override SRC_URI in a bbappend file to point at a different source # tree if you do not want to build from Linus' tree.
SRC_URI = "git://github.com/beagleboard/linux.git;branch=${BRANCH};nocheckout=1;name=machine"

LINUX_VERSION ?= "3.14"
LINUX_VERSION_EXTENSION ?= "-custom"

# Override SRCREV to point to a different commit in a bbappend file to # build a different release of the Linux kernel.

PR = "r1"
PV = "${LINUX_VERSION}+git${SRCPV}"

# Override COMPATIBLE_MACHINE to include your machine in a bbappend # file. Leaving it empty here ensures an early explicit build failure.
COMPATIBLE_MACHINE = "beaglebone"

文件名：linux-yocto-chipsee_3.14.bbappend
文件路径：/ home / ankur / yocto_daisy / poky / meta-ybdevelop / recipes-example / linux

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:"
SRC_URI_append = " file://defconfig"

defconfig路径：/home/ankur/yocto_daisy/poky/meta-ybdevelop/recipes-example/linux/linux-yocto-chipsee_3.14

通过上面的配置，我可以获取并打开获取的linux内核的menuconfig，我使用的命令如下，

# bitbake linux-yocto-chipsee -c menuconfig

但是当我尝试使用下面的命令编译Linux时，它会出错，

# bitbake linux-yocto-chipsee -c compile

获取与gcc相关的错误:(

 /bin/sh: 1: arm-poky-linux-gnueabi-gcc: not found
| make[4]: *** [scripts/mod/empty.o] Error 127
| make[3]: *** [scripts/mod] Error 2

当我尝试使用下面的命令构建时，它也失败了。

# bitbake linux-yocto-chipsee -c build

任何帮助/指针/提示/建议来编译它？

谢谢，

此致 ANKUR

我暂时下载了Yocto_daisy（1.6）工具链并将其安装在我的电脑上。并编译了Linux外部的Yocto构建。这是步骤我在安装了ubuntu的virtualbox中执行了以下步骤。

在Yocto_daisy中使用以下命令构建core-image-sato，

bitbake core-image-sato
使用rootfile系统准备micro SD卡，SPL＆amp; U-Boot，uImage，dtb，uEnv.txt。
使用以下命令克隆beaglebone black Linux

git clone --depth = 1 https://github.com/beagleboard/linux
从以下链接下载yocto-1.6（雏菊）工具链。

http://downloads.yoctoproject.org/releases/yocto/yocto-1.6/toolchain/
根据您的机器类型从i686或x86_64下载我下载了toochain http://downloads.yoctoproject.org/releases/yocto/yocto-1.6/toolchain/i686/poky-eglibc-i686-core-image-sato-armv7a-vfp-neon-toolchain-1.6.sh
通过运行下载工具链脚本安装工具链。默认情况下，它会安装到opt目录中，我将其安装在默认路径中。
在终端遍历到上面下载的Linux目录。并通过运行以下命令
设置工具链环境
source /opt/poky/1.6/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi
现在使用以下命令

制作bb.org_defconfig

然后使用以下命令构建内核

使uImage LOADADDR = 0x80008000 -j4
现在我们将使用以下命令将模块安装到本地目录中，

mkdir bbb_modules
export INSTALL_MOD_PATH = / home / ankur / linux / bbb_modules /
make modules_install
当构建内核时，将uImage（来自/ arch / arm / boot）和am335x-boneblack-bbb-exp-c.dtb（来自/ arch / arm / boot）复制到micro SD卡的BOOT分区。

对于FYI，我的uEnv.txt看起来像这样

Disable: HDMI
bootargs=console=ttyO1,115200n8 root=/dev/mmcblk0p2 rootfstype=ext4 rw rootwait;
bootcmd=mmc rescan ; mmc dev 0 ; fatload mmc 0 0x80007fc0 uImage ; fatload mmc 0 0x80F80000 am335x-boneblack-bbb-exp-c.dtb ; echo Ankur... ${bootcmd}; bootm 0x80007fc0 - 0x80F80000;
uenvcmd=boot;

11。现在使用以下命令将模块从本地目录复制到micro SD卡

cp -a /home/ankur/linux/bbb_modules/lib /media/ankur/ROOT/
sync

12。弹出卡片将其放入Beaglbone Black并打开BBB + LCD。

我还没有让Touch校准适用于LCD，但一旦找到它我会更新答案。

另一个待定的事情是将内核构建到Yocto构建系统中。完成后我会更新答案。

希望这可以帮助有同样问题的人。

将Robert Nelson的Linux内核构建为Yocto（daisy），用于beaglebone black
