繼續 OSPF

試著把 ospfd 叫起來後發現我不知道怎麼來驗證 ospf 的功能

試著 google 幾篇文章來科普一下

Case Study 2 - OSPF simple

下午讓腦子休息一下

先進行 emmc 相關的工作

注意到目前 mfgtool 使用的 mksdcard.sh.tar

自己對於這個主題相關的探索有

先利用 USB 隨身碟插一張 8GB SD 卡來練習

利用 cat /proc/partitions 來觀察

➜  www git:(develop) ✗ cat /proc/partitions
major minor  #blocks  name

  11        0    1048575 sr0
   8        0  125829120 sda
   8        1  123730944 sda1
   8        2          1 sda2

   8       17     512000 sdb1
   8       18    7147520 sdb2

解開 mksdcard.sh.tar 得到 mksdcard.sh

目前 mksdcard.sh 內容如下

#!/bin/sh

# partition size in MB
BOOT_ROM_SIZE=10

# wait for the SD/MMC device node ready
while [ ! -e $1 ]
do
sleep 1
echo “wait for $1 appear”
done

# call sfdisk to create partition table
# destroy the partition table
node=$1
dd if=/dev/zero of=${node} bs=1024 count=1

sfdisk --force ${node} << EOF
${BOOT_ROM_SIZE}M,500M,0c
600M,,83
EOF

解析 dd if=/dev/zero of=${node} bs=1024 count=1

這要在 /dev/sdb 操作的話變成 dd if=/dev/zero of=/dev/sdb bs=1024 count=1

實際操作後如下

看來就是把 /dev/sdb 的前 1024 bytes 寫成 dev/zero

注意到 cat /proc/partition 相關於 sdb 的前後差別

dd 前

   8       16    7761920 sdb
   8       17     512000 sdb1
   8       18    7147520 sdb2

dd 後

   8       16    7761920 sdb

發現到 sdb1 和 sdb2 都不見了

1555

注意到 mksdcard.sh 裡以下的敘述

sfdisk --force ${node} << EOF
${BOOT_ROM_SIZE}M,500M,0c
600M,,83
EOF

把 ${node} 和 ${BOOT_ROM_SIZE} 換成實際的數值後得到

sfdisk --force /dev/mmcblk0 << EOF
10M,500M,0c
600M,,83
EOF

若要在 /dev/sdb 做實驗的話

sfdisk --force /dev/sdb << EOF
10M,500M,0c
600M,,83
EOF

實際操作的紀錄如下

➜  www git:(develop) ✗ sudo sfdisk --force /dev/sdb << EOF
10M,500M,0c
600M,,83
EOF

稍微理解了 sfdidk 的使用方式之後

稍微前進的腳步為再建立一個 partition 讓開機時可以做 mount 的練習

sfdisk --force /dev/sdb << EOF
10M,500M,0c
600M,360M,83
1G,,83
EOF

實際操作如下

造樣造句

解壓 mksdcard.sh.tar 得到 mksdcard.sh

➜  OS Firmware git:(develop) ✗ tar xvf mksdcard.sh.tar
mksdcard.sh

編輯 mksdcard.sh 再壓縮回 mksdcard.sh.tar

➜  OS Firmware git:(develop) ✗ vi mksdcard.sh
➜  OS Firmware git:(develop) ✗ rm mksdcard.sh.tar
➜  OS Firmware git:(develop) ✗ tar cvf mksdcard.sh.tar mksdcard.sh
mksdcard.sh
➜  OS Firmware git:(develop) ✗ rm mksdcard.sh

解壓再次確認 mksdcard.sh 的內容

➜  OS Firmware git:(develop) ✗ tar xvf mksdcard.sh.tar
mksdcard.sh
➜  OS Firmware git:(develop) ✗ cat mksdcard.sh
#!/bin/sh

# partition size in MB

dd if=/dev/zero of=${node} bs=1024 count=1

利用 mfgtool 燒錄

開機

目標 /dev/mmcblk1p3 出現

試著 mount 看看

root@m300e:~# mkdir /mnt/test
root@m300e:~# mount -t ext3 /dev/mmcblk1p3 /mnt/test/
mount: mounting /dev/mmcblk1p3 on /mnt/test/ failed: Invalid argument
root@m300e:~#

回頭看一下 ucl2.xml

我應該要先利用 mkfs.ext3 來格式化 /dev/mmcblk1p3

修一下 ucl2.xml

mfgtoo 燒錄... ok

開機

這次就 mount 成功囉

root@m300e:~# mkdir /mnt/test
root@m300e:~# mount -t ext3 /dev/mmcblk1p3 /mnt/test/
root@m300e:~#

看看我在 ucl2.xml 放的 hello world

root@m300e:~# cat /mnt/test/test
hello world
root@m300e:~#

哈哈哈

大進展阿...

    emmc first step
    - create another partion
    - after power on, use the following commands to see our beatiful first step:
      - mkdir /mnt/test
      - mount -t ext3 /mnt/dev/mmcblkp3 /mnt/test
      - cat /mnt/test/test
