re: MAC address

You can't do it all with one button. You have to hold the device in its reset state, hold MISO low, then release reset before you release MISO. Also, you definitely shouldn't have a pullup resistor with a capacitor to GND since this will act like a short to the high frequency (16MHz) data signal on the MISO connection between the JN51xx and the flash device.

If you remove the resistor & capacitor, you should be able to put it into programming mode by holding the button down while there is no power to your board, then while still holding the button down, turn it on.
