Hi,

I would recommend you to put the weak pull up and weak pull down resistor on the JTAG lines as this is needed for you to performed JTAG configuration initially. Without the resistor you will not be able to program the Max 10 device initially. Once you have programmed the On-Chip Flash then you may removed the resistor if you no longer need to use the JTAG connection.
