LCD display problem

Hi William, did you talk to me ?

Hi William
I made the cable

Hi，its well.
you can burn all the firmware.
Motherboard firmware: A30_M07_V2_01.bin
Motherboard boot program: MotherBoot_bootloader_V3.0.bin
LCD screen firmware: A30_S02_V0_02.bin
LCD screen boot program: LCD_bootloader_V3.0.hex
You can follow these steps:
1. Burn the motherboard boot program: The motherboard boot program uses the "Flash Loader Demo" burning tool to burn.
2. Burn the motherboard firmware: The motherboard firmware is burned using the "firmware_tool_V2.0" burning tool.
3. Screen boot program: The screen boot program uses the ST-LINK emulator for burning, and it needs to connect the computer and the screen with a cable (note that the screen line should be inserted into the interface below the screen, as shown in the figure.After the programming is completed, connect the interface to the one above.).
4. Burn screen firmware: The application uses the “firmware_tool_V2.0” burn tool to burn (the same as the method of burning the Screen boot program), or fill in the address 0x08010000 when burning with ST-LINK.
Since the motherboard boot program and firmware were already burned when it left the factory, you only need to re-burn the screen boot program and screen firmware.
If it is still unavailable, you can burn all of them again.

Hi，it's software, I suggest you can wait for us to send you the screen with the firmware already burned.
