Hi.
We use a MK20DX256 on our own boards. Thereby we have a strange behavior after booting. The device does not go to the main routine after start up. If we toggle the RESET pin manually to low, the user program starts running and everything works fine. The RESET pin is connected with a 10k resistor to VCC and with 100nF to GND. We have no idea what is the problem, maybe the controller goes in bootloader mode after a regular power cycle or something like that.
Do you have an idea in which direction we have to look for a solution for this problem?
Thank you for your help.
Regards Felix
