Step 1 : Connect the VGA ISP of flashing programmer with the VGA port of liquid crystal board using VGA line(using the original packing VGA line); ![](https://box.kancloud.cn/ed92e8733c4266dff4c82414ebd00009_554x256.png) Step 2 : At first click the![](https://box.kancloud.cn/4920098af75b688d5aebd51e4435a3a0_123x22.png)in the software interface to set; ![](https://box.kancloud.cn/ad0f947b01b9c8a72116a8466e63ef37_598x534.png) Step 3 : Set when the window pops up. VGA line orders type : The different mainboard will use the different line orders, if it can’t on line,please choose different line orders to test repeatedly. Serial port speed : That is baud rate adjustment,the baud rate of different mainboard is different.If the printing message is messy code please try to change the baud rate. After adjusting the parameter please click to save. ![](https://box.kancloud.cn/dfd13183f8791b410ca34a7c21961c40_501x447.png) Step 4 : After setting the parameter,click![](https://box.kancloud.cn/c19dec7a2fd5f6c5811dd4a7250abf61_123x22.png),open the serial and electrify the mainboard in 2 seconds,the printing message will appear in the following dialog. ![](https://box.kancloud.cn/074e2025a114b9c23e4742209ec3429f_515x308.png) Attention : If the printing message haven’t been appeared,please pay attention to following questions First click![](https://box.kancloud.cn/c19dec7a2fd5f6c5811dd4a7250abf61_123x22.png),then supply power to the mainboard; Some mainboards need to be supplied power in the stand-by mode and also the main power supply; If the line orders are not correct,please change it in the parameter setting and then try again; When the serial port of some mainboards is at HDMI or reserved port,it needs to connect HDMI or fly lines,that is to connect SCL,SDA,GND lines with the SCL,SDA,GND on the mainboard; ![](https://box.kancloud.cn/ed92e8733c4266dff4c82414ebd00009_554x256.png) The serial ports of some mainboard need to be opened in the factory pattern.
