GPIOs at DIMM-MX257
Have the DIMM-MX257 only 6 GPIO pins?
emtrion's SODIMM concept has 10 pins specified for GPIO function. With DIMM-MX257 you can use 6 pins as input and output. These 6 pins are always available, whatever other interfaces are in use. If more than 6 GPIO pins are needed, you can use the pins from unused CPU interfaces. For example, if you don't need the SPI interface, you can use these pins as additional GPIOs.
