I got my board and started in Arduino with the first sketch, after selecting the right USB-Port (cu.usbmodem14301 if I remember right). All was fine.
After some coding tests and uploading to the board the display is black/not showing anything, the green LED is on and the red LED is blinking very fast overtime the board get power.
If I try now to upload another sketch via Arduino to the board, the USB-Port is not visible anymore. Reboot the computer was not helpful.
My fault. After looking for similar issue here I found a closed one. Holding the boot button during power plug was the solution. Now the USB-Port is visible again.
Hello,

Any idea what's broken?
