>unsigned long new_state = *(unsigned*)SA11X0_GPIO_PIN_LEVEL; >SA11X0_GPIO_PIN_LEVEL must obviously be a memory address for card slot >state information. Does anyone have any idea where this would be for >the EDB7111-2 board? It's a 32-bit value referencing the 28 GPIO pins on the SA1100/1110. The masking of these bits depends on how the particular implementation chose to wire the signals to PCMCIA signals; the GPIO bits are as the name implies "general purpose" and not specifically dedicated to PCMCIA functions. On the 7312 the bits you need will be in the PORTA,B,C,D,E registers. (I have the EDB7209 with 7212 on it, no PS6700, so I don't know how Cirrus wired it). -- Lewin A.R.W.
