Timers stop working when I instantiate a USB Device on Nucleo-F429ZI board.
I can make a USB device (MIDI in this case) work on this board, and I can make timers work on this board with an overflow interrupt toggling an I/O, but when I try to use both, the timer appears to stop working(interrupt routine stops toggling the I/O). I tried this with Timers 2, 3, 4, and 7 and non of them work. There is no code in the USB stack that appears to be using a timer. I don't even need to be using the USB. As soon as I add an instance of a USB device to my declarations, the timer stops functioning. Any ideas?
