将罗伯特·纳尔逊的Linux内核构建为Yocto（雏菊），用于beaglebone黑色 [英] Building Robert Nelson's Linux kernel into Yocto(daisy) for beaglebone black
问题描述
我正在尝试从官方的存储库构建用于beaglebone黑色的Linux https://github.com/beagleboard/linux
I was trying to build Linux for beaglebone black from official repository https://github.com/beagleboard/linux
我能够获取并运行menuconfig，但是当我尝试编译内核时，我会收到错误。
I am able to fetch and run menuconfig but when i try to compile the kernel i get error.
以下是配方文件的内容。

使用上述配置，我可以获取并打开已读取的linux内核的menuconfig，我使用的命令是遵循，
With above configuration i am able to fetch and open menuconfig for fetched linux kernel, command i used is as follows,
# bitbake linux-yocto-chipsee -c menuconfig
但是，当我尝试使用以下命令编译Linux时，会出现错误，
But when I try to compile Linux using below command it gives error,
# bitbake linux-yocto-chipsee -c compile
获取与gcc相关的错误： / p>
getting error related to gcc :(

当我尝试使用下面的命令建立时间也失败了。
When i try to build using below command that time also it failed.
# bitbake linux-yocto-chipsee -c build

This usually means one provides something the other doesn't and should.

推荐答案
很久以前，我下载了Yocto_daisy（1.6）工具链，并将其安装在我的电脑中。并编译了Linux外部的Yocto构建。以下是步骤。
我按照以下步骤在我的虚拟机中安装了ubuntu。
Well for time being i downloaded the Yocto_daisy(1.6) toolchain and installed it in my PC. And compiled the Linux external to Yocto build. Here are steps.
I followed below steps in my virtualbox installed ubuntu.
-
在Yocto_daisy构建核心-image-sato，使用以下命令，
in Yocto_daisy build core-image-sato, using following command,
bitbake core-image-sato
bitbake core-image-sato
准备微带根文件系统的SD卡，SPL& U-Boot，uImage，dtb，uEnv.txt。
Prepare micro SD card with rootfile system, SPL & U-Boot, uImage, dtb, uEnv.txt.
使用以下命令克隆beaglebone黑色Linux
Clone beaglebone black Linux using following command
git clone --depth = 1 https://github.com/beagleboard/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。
Download yocto-1.6(daisy) toolchain from following link.
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
我下载了以下的太多。
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downloa安装工具链d工具链脚本。默认情况下，它安装到opt目录中，我将其安装在默认路径中。
Install toolchain by running download toolchain script. By default it installs into opt directory, I installed it in default path.
终端遍历到上述下载的Linux目录。并通过运行以下命令设置工具链环境：
In terminal traverse to the above downloaded Linux directory. and set toolchain environment by running following command,
source /opt/poky/1.6/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi
source /opt/poky/1.6/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi
现在使用以下命令配置内核，
Now configure kernel using following command,
make bb.org_defconfig
make bb.org_defconfig
-
然后使用以下命令构建内核
and then build kernel using following command
make uImage LOADADDR = 0x80008000 -j4
make 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，
now we shall install the modules into local directory using following commands,
mkdir bbb_modules
export INSTALL_MOD_PATH = / home / ankur / linux / bbb_modules /
make modules_install
mkdir bbb_modules
export INSTALL_MOD_PATH=/home/ankur/linux/bbb_modules/
make modules_install
复制 uImage （from / arch / arm / boot）和 am335x-boneblack-bbb-exp-c .dtb （从/ arch / arm / boot）到micro SD卡的BOOT分区。
when kernel is built copy uImage(from /arch/arm/boot) and am335x-boneblack-bbb-exp-c.dtb(from /arch/arm/boot) to the BOOT partition of the micro SD card.
对于FYI，我的uEnv.txt看起来像这样
For FYI my uEnv.txt looks like this
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，
11 . Now copy modules from local directory to the micro SD card, using following commands,
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电源。
12. Eject the card put it into Beaglbone Black and power on the BBB+LCD.
我还没有得到液晶显示器的Touch校准工作，但一旦我找到它，我会更新答案。
I am yet to get the Touch calibration working for LCD but once I find it i will update the answer.
另一个待处理的事情是将内核构建到Yocto构建系统中。
Another pending thing is build above kernel into Yocto build system. I will update the answer once i am done with that.
希望这可以帮助有同样问题的人。
Hope this helps someone with the same issue.
