I've this one and need to connect the VCC, GND, SWDIO and SWCLK of the SKlink to the LCD board but I do not know what is the pin setting of this LCD board and I do not find it anywhere. SD updating does not work. I've read that I should copy only the content of the UI folder to the SD card. Or do I've to copy all of the firmware file ?

Hi
I received the screen today and I installed it as you told me, it turned on, but when I clicked on the icons nothing happened.
The sd card in the control box slot is empty.
I ask you what to do first to avoid creating a problem.
Should i copy some files to the sd card, if yes, which files ?
Thank you.

Hi,is the motherboard firmware burned?
You need to restore the factory settings.
If the screen does not respond, it may be that the screen cable is not plugged in properly, you can unplug it again.

Yes, the screen we sent you is burned firmware. If it cannot be clicked, there may be a problem with the screen. Can you show me the screen wiring? you can do this:
1. How to burn motherboard firmware:
Motherboard application: A30_M07_V2_01.bin (CRC32: 4E6ED0BA)
Motherboard boot program: MotherBoot_bootloader_V3.0.bin (CRC32: A81D6687)

The motherboard boot uses the "Flash Loader Demo" programming tool for programming, and the motherboard application uses the "firmware_tool_V2.0" programming tool for programming and must be the firmware_tool tool of version V2.0 or later.
2. There is also a way to burn the screen, you can try it with the first screen.

If there is no problem with the hardware, you should be able to use it after these operations.
Hope to help you!
