The Mistral board has the wakeup button (SW1) wired to the LCD 3.3V rail, which is powered down during suspend. To allow this button to wake up the omap, it must be rewired to the main 3.3V rail.

  1. Rotate R10 (the resistor directly behind SW1) so it is only connected to the pad near TP23
  2. Solder a thin wire to the floating end of R10 and drop it through the slot for the LCD cable
  3. Solder the other end of the wire to the 3.3V rail (pin #10 on connector J5)
