unable to flash firmware / revert to BT firmware #38

Closed cropduster closed 3 years ago

Hi there,

I wanted to reflash my TFT35 to BTT firmware, and no mater what SD card or USB stick I choose, it does not flash the firmware. I renamed the .bin to firmware.bin, FIRMWARE.bin and took he original name... nothing works.

Using the original BTT firmware file name should work. Which BTT firmware did you use? 26 oder 27?

cropduster commented 3 years ago

I have currently your NoTouch v1.3 running and tried to flash to BTT 27.

teeminus commented 3 years ago

Try flashing the BTT 26.

However, flashing of the firmware is done by the bootloader of the display, not by the firmware itself.

cropduster commented 3 years ago

Didn't work with BTT 26 either... immediately the splash screen "ST7920Emulator ready" is shown.

What is your flashing procedure?

cropduster commented 3 years ago

Sd card in (alternatively: USB stick in) - printer off/on (alternatively: push button on TFT)

cropduster commented 3 years ago

...ok, it works now...
