HSMC GPIO Daughter card.

I am beginningn to think we need to start a new thread about the pin voltage. I just found out that HSMC_TX_D_p(16) gives 2,38V when high, and HSMC_RX_D_p(15) provides 2,42V. This seems to be a small difference, but I use these two pins (among other pairs with similar problems) to control a motor[controller], and then it transmits a PWM signal, and the difference becomes a problem. The motor does turn one way, but not the other. Any suggestions? Should I change the jumper to select another IO standard, this might make the difference proportionally smaller, but the main problem still exists.
