Boot Procedure

Hi there, I have 2 motors running off pwm from an olimexino maple clone. The motors are connected to pins D0/1/2 and D3/4/5 with D0 and D3 being the pwm pins, the others the Hi/Lo to specify direction.

If I reset the maple it goes through some sort of boot procedure before my program starts. One of the motors goes into full throttle for the duration of the boot which is several seconds. (Sorry, not near my board so not sure which one) I guess the boot procedure must write high to some of those pins. Anyone know if there's a way to stop this?

Thanks!

When the board resets the pins go high impedance, depending on your motor driver this could cause the motor to turn on. As a simple check, put a 10KΩ resistor from the pin in question to ground.
