Hi, all,
I worked on the PCMCIA module for my MPC 857T based board.
I downloaded the pcmcia-cs 3.1.29 and modified the file modules/m8xx_pcmcia.c.
My board uses the SLOT B. What I did are just like the (F)ADS and RPXLite.
I compiled the resulted pcmcia module and loaded them into linux kernel using "insmod".
1. insmod pcmcia_core.o
2. insmod m8xx_pcmcia.o
3. insmod ds.o
Here comes the problem.
When I inserted ds.o, the driver tells me that "cs: socket 0 timed out during reset"
I looked through the source code and the debug info.
I found that a lot of the same messages as follows:
GetStatus(0) = 0x190
...
Such info come from m8xx_pcmcia.c/m8xx_get_status. It seems that someone
is not satisfied with the above return value and " get status " again and again.
Then it quit.
Any suggestions are highly appreciated!
Thanks a lot
Rolf

To look at it a different way - the driver was unhappy with the value of
the first inb() on an address in the card's I/O space.
My first guess (been there myself) is that inb() and outb() aren't
working to your card's I/O space.

I'm not familiar with the 857T pcmcia, perhaps the timing is different.
Check the timing calculation functions against the 857T UM.
