Trying to get PCMCIA cards working in an IPAQ PDA. Some Success and some Failure.

Hi,

I wrote a message a couple of days before. I finally got the SuperLogic PCM 
208H PCMCIA card working on the LapTop computer but not in the PDA. I have 
tried to trace the driver and found that although the configuration process 
is succesful, no communication exists with the card. When the driver tries to 
access the card via "inb" or "outb" no writings nor readings take place (all 
the values read are always 0 for all the registers, and writing to the DAC 
registers has no effect).  

As I reported previously, the NI DAQ 6036E PCMCIA card works OK for the PDA. 
The configuration steps of the PCMCIA stuff of both card drivers are quite 
similar, and in both cases the same I/O space area and IRQ are asigned when 
inserted in the same slot. However the NI DAQ 6036 is correctly accessed 
through "inb" and "outb" and the PCM208H is not. 

In the case of the LAPTOP, both card are asigned to the I/O port address space 
(at 0x100 base address). In the case of the PDA it seems to be not I/O port 
address space, the allocated address space in both cases is 
0xf6000000-0xf600000f. 

As before, I would appreciate any help, comment or hint in this subject. Also, 
recommendations and documentation pointers for driver hacking would be 
welcomed.

Best Regards and thank you in advance,

	Jose Manuel
