1. 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；
   
2. 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；
   
3. 长时间复制粘贴，烧录核心板的效率会慢慢降低

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。

Sigma核心板。

• 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。
