BBBのkernelの再構築を試みる。
makeの手順は以下で詳しく説明されている。
http://wiki.beyondlogic.org/index.php/BeagleBoneBlack_Building_Kernel
上記URLでの手順ではKernel3.12で説明されているが、今回は作成したmicroSDの環境の Kernelの換装が目的であるので、Kernel3.8で手順をなぞる。
先ずはクロスコンパイルのtool-chainとgit、u-bootをインストールする。
temp-host@temp-host:~$ sudo apt-get install gcc-arm-linux-gnueabi temp-host@temp-host:~$ sudo apt-get install git temp-host@temp-host:~$ git config --global user.email "temp-host.email@temp-host.com" temp-host@temp-host:~$ sudo apt-get install lzop temp-host@temp-host:~$ wget ftp://ftp.denx.de/pub/u-boot/u-boot-latest.tar.bz2 temp-host@temp-host:~$ tar -xjf u-boot-latest.tar.bz2 #cd into u-boot directory temp-host@temp-host:~$ cd u-boot-2014.07 temp-host@temp-host:~$ make tools-only temp-host@temp-host:~$ sudo install tools/mkimage /usr/local/bin temp-host@temp-host:~$ mkdir bbb_kernel.3.8 temp-host@temp-host:~$ cd bbb_kernel.3.8/ temp-host@temp-host:~/bbb_kernel.3.8$ git clone git://github.com/beagleboard/kernel.git Cloning into 'kernel'... remote: Counting objects: 31953, done. remote: Total 31953 (delta 0), reused 0 (delta 0) Receiving objects: 100% (31953/31953), 17.51 MiB | 4.27 MiB/s, done.

Switched to a new branch '3.8'
patch.shを実行。
ちなみにpatch.shの実行は仮想環境でのゲストOSでは一時間半以上かかる。
ログは長いので省略する。
temp-host@temp-host:~$ ./patch.sh
次にdefconfigの差し替えを行う。
temp-host@temp-host:~/bbb_kernel.3.8/kernel$ cp configs/beaglebone kernel/arch/arm/configs/beaglebone_defconfig temp-host@temp-host:~/bbb_kernel.3.8/kernel$ wget http://arago-project.org/git/projects/?p=am33x-cm3.git\;a=blob_plain\;f=bin/am335x-pm-firmware.bin\;hb=HEAD -O kernel/firmware/am335x-pm-firmware.bin --2014-09-14 01:21:31-- http://arago-project.org/git/projects/?p=am33x-cm3.git;a=blob_plain;f=bin/am335x-pm-firmware.bin;hb=HEAD arago-project.org (arago-project.org) をDNSに問いあわせています... 184.73.161.183 arago-project.org (arago-project.org)|184.73.161.183|:80 に接続しています... 接続しました。 HTTP による接続要求を送信しました、応答を待っています... 200 OK 長さ: 10796 (11K) [application/octet-stream] `kernel/firmware/am335x-pm-firmware.bin' に保存中 100%[======================================>] 10,796 61.7KB/s 時間 0.2s 2014-09-14 01:21:32 (61.7 KB/s) - `kernel/firmware/am335x-pm-firmware.bin' へ保存完了 [10796/10796] temp-host@temp-host:~/bbb_kernel.3.8/kernel$ cd kernel temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- beaglebone_defconfig -j4 HOSTCC scripts/basic/fixdep HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf drivers/video/Kconfig:60:error: recursive dependency detected! drivers/video/Kconfig:60: symbol FB is selected by DRM_KMS_HELPER drivers/gpu/drm/Kconfig:28: symbol DRM_KMS_HELPER is selected by DRM_TILCDC drivers/gpu/drm/tilcdc/Kconfig:1: symbol DRM_TILCDC depends on BACKLIGHT_LCD_SUPPORT drivers/video/backlight/Kconfig:5: symbol BACKLIGHT_LCD_SUPPORT is selected by FB_BACKLIGHT drivers/video/Kconfig:247: symbol FB_BACKLIGHT is selected by PMAC_BACKLIGHT drivers/macintosh/Kconfig:134: symbol PMAC_BACKLIGHT depends on FB warning: (USB_MUSB_HDRC) selects TWL6030_USB which has unmet direct dependencies (USB_SUPPORT && (USB || USB_GADGET) && TWL4030_CORE && OMAP_USB2 && USB_MUSB_OMAP2PLUS) warning: (DVB_USB_PCTV452E) selects TTPCI_EEPROM which has unmet direct dependencies (MEDIA_SUPPORT && MEDIA_PCI_SUPPORT && MEDIA_DIGITAL_TV_SUPPORT && I2C) warning: (USB_MUSB_HDRC) selects TWL6030_USB which has unmet direct dependencies (USB_SUPPORT && (USB || USB_GADGET) && TWL4030_CORE && OMAP_USB2 && USB_MUSB_OMAP2PLUS) warning: (DVB_USB_PCTV452E) selects TTPCI_EEPROM which has unmet direct dependencies (MEDIA_SUPPORT && MEDIA_PCI_SUPPORT && MEDIA_DIGITAL_TV_SUPPORT && I2C) # # configuration written to .config #
準備が整ったのでkernelとdtbsをmakeする。
temp-host@temp-host:~/bbb_kernel.3.8/kernel$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage dtbs LOADADDR=0x80008000 -j4
Kernelのフルビルドであるが10分程度。
ログは長いので省略する。
引き続きmodulesのmakeを行う。
temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- modules -j4
特に問題無くmakeが完了。
ログは長いので省略する。
Kernel makeの成果物は以下
temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$ ls -la ./arch/arm/boot/ 合計 15776 drwxrwxr-x 5 temp-host temp-host 4096 9月 14 01:39 . drwxrwxr-x 87 temp-host temp-host 4096 9月 14 01:13 .. -rw-rw-r-- 1 temp-host temp-host 107 9月 14 01:39 .Image.cmd -rw-rw-r-- 1 temp-host temp-host 46 9月 14 00:57 .gitignore -rw-rw-r-- 1 temp-host temp-host 243 9月 14 01:39 .uImage.cmd -rw-rw-r-- 1 temp-host temp-host 134 9月 14 01:39 .zImage.cmd -rwxrwxr-x 1 temp-host temp-host 7250272 9月 14 01:39 Image -rw-rw-r-- 1 temp-host temp-host 3404 9月 14 01:10 Makefile drwxrwxr-x 2 temp-host temp-host 4096 9月 14 00:57 bootp drwxrwxr-x 2 temp-host temp-host 4096 9月 14 01:39 compressed drwxrwxr-x 3 temp-host temp-host 36864 9月 14 01:28 dts -rw-rw-r-- 1 temp-host temp-host 1274 9月 14 01:06 install.sh -rw-rw-r-- 1 temp-host temp-host 4408216 9月 14 01:39 uImage -rwxrwxr-x 1 temp-host temp-host 4408152 9月 14 01:39 zImage temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$
これでkernel関連のmakeは完了した。
実は6月に試した際はいくつもの問題があり色々細工が必要であった。
9月現在ではスムーズに完了するようになっている。
ubootやrootfsを一から再構築するのは面倒であるので、これまでに構築したmicroSDカードのものを流用することとし、 上記makeの生成物をmicroSDカードの内容と差し替える。
debianなのでdpkgが使えるのかもしれないが、原始的に手動コピーで行う。
母艦(ゲストOS)でこれまでに構築したmicroSDカードを認識させる。
母艦(ゲストOS)に/media/temp-host/BEAGLE_BONE/として認識されたとして手順を進める。
先ずはzImageおよびdtbsの内容物を手動でコピーする。

zImageおよびdtbsの内容物は一応バックアップを取ることとする。
しかしこのパーティションの容量は少ないし、ディスクイメージは残してあるのでバッサリ消してしまっても構わない。
残すとしても母艦(ゲストOS)に残すので良いだろう。
次にmodulesのinstallを行う。
母艦(ゲストOS)に/media/temp-host/rootfs/として認識されたとして手順を進める。
temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$ sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- INSTALL_MOD_PATH=/media/temp-host/rootfs modules_install
ログは長いので省略
数分で完了する。 一応syncを行う。
temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$ sudo sync temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$ sudo sync temp-host@temp-host:~/bbb_kernel.3.8/kernel/kernel$ sudo sync
丁寧ではないが、一応これで立ち上がるはずだ。
母艦(ゲストOS)からmicroSDカードを抜きBeagleBone Blackに挿入して起動を行う。
母艦(ホストOS)からUSBシリアルTTLケーブルを介し、TeraTermでシリアル接続を行い起動を試みる。

Kernel Versionが3.8.13-00770-g94e9a39に変わっている事を確認。
以下のアラートが出るのはinitrd.imgが古い為。

引き続きinitrd.imgの更新を行う。

initrd.imgが2957458Byteから6950530Byteに膨れ上がってしまっている。
initrd.imgの作り方が間違っているのかもしれないし、kernel configのせいかもしれない。
とりあえずパーティション容量内に収まっているので良しとする。
rebootを行う。

なぜかBBBからNFSがマウントできなくなっている。
debian@beaglebone:~$ sudo mount 192.168.1.19:/home/temp-host/nfsroot /mnt/hostnfs
mount: wrong fs type, bad option, bad superblock on 192.168.1.19:/home/temp-host/nfsroot,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so
dmesgを見ても理由が良く判らない。
google検索すると似たトラブルが出ていて、nfs-commonをインストールすると解決した報告があった。

BBB側でnfsのmountを試みる。

ホスト側でもtest.txtが生成されている事を確認。
nfsがmountできる事は確認できた。
kernelを差し替える前と後で、設定が異なる部分がどうもあるようだ。
ただ、細かく調べる時間は無いのでとりあえず問題毎に対処するか諦めることとする。
何にせよソースコードと対応の取れたKernel環境一式が出来上がったので、必要に応じてkernelを弄れるようになった。
