invalid header: 0xffffffff
thats what the thonny IDE is saying,
so that is why it disconnects the usb after connecting for 1 sec
Is there a option to turn the header reading off in windows? so it just connects and does nothing? Can't find anything on google

I flashed my T-Display S3 board with this firmware https://github.com/russhughes/st7789s3_mpy
I used the Thonny IDE for flashing. Everything was loaded but now I have a problem. When I connect the board to the PC via USB, it recognizes the board for a second and then loses it again. Im using WIN10, I see the whole time poping up "USB JTAG/Serial debug unit eject" for a second and then disappear. Before I flashed it I had no problems with the USB connection. Did I break the board or is there anything I can do?

@russ thank you!

Hello, would it be possible to release a Micropython display driver for the T-Display-S3? Would be really awesome! I think a lot of people would buy it if it would be possible.
