続：armhf.comで配布しているUbuntuイメージはボタン押さないと起動できない件

bbb

http://d.hatena.ne.jp/kinneko/20140115/p2 の続き。


しょうがないので、実機で起動してみる。


書き込むイメージのサイズは1.8GB。

kinneko@L2012:~/BBB_ubuntu$ ls -lh ubuntu-saucy-13.10-armhf-3.8.13-bone30.img
 -rw-r--r-- 1 kinneko kinneko 1.8G Jan 15 09:10 ubuntu-saucy-13.10-armhf-3.8.13-bone30.img

手元にあった8GBのmicroSDに書き込む。

kinneko@L2012:~/BBB_ubuntu$ sudo dd if=ubuntu-saucy-13.10-armhf-3.8.13-bone30.img of=/dev/sdb
3751936+0 records in
3751936+0 records out
1920991232 bytes (1.9 GB) copied, 1043.72 s, 1.8 MB/s


Beagebone blackにシリアルコンバーターを付けて、minicomで作業マシンにコンソールが出るようにする。
作成したmicroSDカードを入れて、ボタンを押さずにそのまま起動する。

なげーよ。
spi, nand, mmcの３パターンの起動設定が書かれている。
これは間違うよ。


bootfile=uImageが間違いかな。

U-Boot# setenv bootfile zImage
U-Boot# printenv
(snip)
bootfile=zImage
(snip)

保存して再起動。

U-Boot# saveenv
Saving Environment to NAND...
Erasing Nand...
Attempt to erase non block-aligned data
U-Boot# reset

結果同じ。

 ** File not found /boot/uImage **
U-Boot# printenv
bootfile=uImage

なんかで上書きされてますな。uEnv.txtにはそれっぽいのはなかったけど。
もしくは保存できてないとか。


直接起動してみる。
ふつーに書くと、たぶん、こんな感じだな。

load mmc 0 0x80007fc0 uEnv.txt
load mmc 0:2 0x80F80000 /boot/dtbs/am335x-boneblack.dtb
load mmc 0:2 0x80007fc0 /boot/zImage
setenv bootargs console=ttyO0,115200n8 fixrtc root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait
bootz 0x80007fc0 - 0x80F80000

ubootのコンソールからそのまま渡してみる。

たぶん、間違いはこれ。

mmcboot=echo Booting from mmc ...; run mmcargs; bootm ${kloadaddr} - ${fdtaddr}

ここbootmじゃなくて、bootzね。
あとこれも。

bootfile=uImage

zImageね。


こいつらをuEnv.txtに反映してみる。
このまま起動したUbuntuで作業する。

ubuntu@ubuntu-armhf:~$ cd /boot/uboot

loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}

再起動。

はい、ボタンなしでも起動してきた。
