接上TX RX 按回车不放通电进入控制台，在CRT页面打印信息下：
输入 panelinfo get set 命令
<< MStar >># panelinfo get set
<< MStar >># panelinfo get set 回车。
<< MStar >># panelinfo get set （这个命令是屏参查询）输入回车就可以查询所有的屏ID了

eeprom read curret panel_id=2（这个2就是之前换EMMC的屏参ID，
<< MStar >># panelinfo set 3 （这个3是我要改的ID数）输入这个命令回车就可以把屏幕ID数改过来了，如果屏参还是不对可以再试别的屏参ID数，这里一共有21种屏参ID，3屏参ID是奇美40寸,3 = 03_MZ_HD_40_0Q_T011
