I thought i was supposed to use the version of firmware that is posted. See my screenshot of the successful LCD firmware update. I have tried the SD slot version many times. That does not work either. I the config.txt file and the bin along with system folder and still blank screen looks Black. Ready to try something different like ST-link that way I know it is burning it to the STM chip. See my previous request.

Thank you. Is this bootloader hex file for the LCD screen that is in the TOP of the image you posted?

Do I need to jumper the Boot0 jumper on the LCD when using the boot loader?

OK then how to I get the display to work. I have updated the firmware on the MB and the display many times using the 2.0 tool and the tool reports successful but the display is still black. I have put the config.txt file, bin file and the system folder on the SD card many times and put the SD in the side of the display and that does not work either. I get no response when I put the SD card in the slot and apply power. I even deleted all files from the SD cards, then formatted the SD cards FAT32 and tried that again and still nothing. I have a black display.

What should I do?

Hi,need to connect first: VCC of ST LINK is 5V. And please pay attention to GND and VCC, look at the color of the line (pictured). You can use the st-link brush to guide when the line is connected correctly.
