5. Core 2 Touchscreen Issues

Core 2 Touchscreen Issues

  • A

    I just received my Core2, I played with some Arduino Examples, and the touch screen won't respond. I tried to use the M5 Burner to restore the factory firmware, and it will upload but not run (screen stays black).

    Here is the code from the upload of the Core2FactoryTest v1.3.1:

    --chip esp32 --port COM10 --baud 1500000 --before default_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x000 C:\Users\bridg\Desktop\packages\firmware\9ba4fa2baa3d86fa6c62d7ace46ea584.bin

  • Hello @awoodbridge

    I get the same result - blank screen. The issue is that the command to download Core2FactoryTest v1.3.1 in M5Burner is not correct for this particular binary. It loads the code to the incorrect address 0x000 - the correct address is 0x1000.

    I suggest you try Core2_Tools v1.0.1 - that binary and download command work for me.

    Thanks

    I tried that program. The screen shows up, but the screen doesn't respond to touch.
