GPIO driver under MQX (alternative)

Hi all,

 

I'm developing a Ethernet bootloader for a MCF54455, using CW10 and MQX 3.6.1 Right now I'm reading the MQX Drivers Users Guide and I realized that my MCU doesn't have MQX GPIO Driver. I don`t really now how does this affect to the MCF54455 ability to access directly to it's pins.

 

Is possible to use other alternatives to access to my MCUs pins under MQX? Witch ones? Maybe MCF54455_GPIO.h? Surely there is a way to do so, but what happens to the MQX tasks then? I mean, is the Real Time Broken? Does the MQX hang?

 

Thanks a lot,
