指的是在测试过程中有对NAND id进行比较的测试项目，old nand id VS new nand id is not match;
such as use jave code to write your test items for this step:
read nand id;0x0022aer0
compare with old nand id(0x0022000);
root cause:
1.when this product has been done DFU,but the board is abnormal to work,and then you have replaced the nand of not do DFU and follow the board to next test station which is includes compare NAND-ID,thus,the issue is happend.

量产是对u盘的设置，把系统映像制作到u盘里，使u盘能够代替光驱来安装系统。量是指批量的意思，即量产工具可以一次性生产出很多u盘，只要你的usb孔足够。 量产工具是针对u盘主控芯片进行操作的由厂商开发的低层软件，作用： 1)低格u盘 2)生产加密盘 3)分区，可以生产只读分区，更改u盘介质类型（removabel 和 fixed） 4)量产出usb－cdrom，此作用可以做启动光盘
