===== 原因 =====

  - 烧录sigma核心板需一条一条复制命令，整个下来大概花费5分钟左右；\\
  - 由于命令是一条一条的复制进去，如果中途出错就会造成烧录不成功或者无法进入后续界面；\\
  - 长时间复制粘贴，烧录核心板的效率会慢慢降低

===== 目的===== 

简化烧录流程，节省烧录时间，减少人为干预造成的失误，确保烧录更加准确。

===== 范围===== 

Sigma核心板。

===== 改进过程 ===== 

  * 通过CRT录制整个烧录核心板的流程，保存脚本并修改（加入循环语句、简化语句）；\\
  * 测试脚本，整个流程需要修改ID“echo 28000034330000001 > /opt/smp86xx/devid”这条语句；\\
  * 第一次重启之后，按原来的方法多次按0，直到出现“YAMON>”即可；\\
  * 改进之后烧录一块完整的核心板只需要一分钟左右，极大的节省了烧录时间，而且人为干预减少，出现错误的可能性降低。

===== 原始命令===== 

''df\\
mount -t yaffs2 -o inband-tags /dev/mtdblock2 /root\\
cd /root\\
rm vmlinux.gz\\
cp /media/usb/disk1/vmlinux.gz  /root/\\
cd /opt/\\
rm -rf *\\
cp /media/usb/disk1/smp86xx.tgz  /opt/ \\
gunzip smp86xx.tgz\\
tar xvf  /opt/smp86xx.tar\\
下面输入ID号\\
echo 28000034330000001 > /opt/smp86xx/devid\\
reboot\\
''

**重启后执行:**

''
rm smp86xx.tar\\
reboot\\
重启后按“0”，进入\\
setxenv y.ipaddr "192.168.1.134"\\
setxenv y.subnetmask "255.255.255.0"\\
setxenv y.gateway "192.168.1.1"\\
net init\\
