I am using an RP240 mounted on an Adafruit Itsy-bitsy board. After successfully loading the bootloader (keeping the BOOT button pressed), I have loaded the Fade example from the recommended library. Everything works correctly. The problem occurs when I upload my own code that I have developed.
I press the load button and after correctly compiling said code, it is loaded onto the board with RP240. After this the USB device disappears and it is not possible to find it in the device manager in Windows 10.
Has anyone experienced this situation or been able to solve it correctly?
PS: I have checked the code on an Arduino UNO with ATmega328p and everything works fine as expected.
PS_2: I leave links to Adafruit Web to configure the board to work with Arduino
