Hello-- I am _still_ working on the pcmcia driver for the inhand Elf. I have run into a really bizzare problem. I am useing a SANDisk ATA card to debug the driver. PCMCIA works fine, as long as I do not try to read from the IO portions that should map to the card, aka when the ide driver tries to do an identify on the card. This means I am able to read all of the attribute memory fine to determine which card I have inserted.
I am using 0xf700|0000 as the base address, as inhand has mapped the pd6722 to 0x3000|0000. The IO space for the sockets has been mapped to 0x3000|0000, and 0x3000|8000 by inhand directly. When I am in the ide driver and do a loop to print the values from 0xf700|0000 to 0xf700|0007, the ide registers that should be on the cards, I get the value 0xa1 for ALL of them. When I use dev2mem to print the values, I get what appear to be different values. Are there any ideas as to why this might be happening? I would be much appreciative to anyone who can help as I have to have this working in the next 2 weeks.!!! Thanks P.S To make the message readable, I have place the dev2mem # dev2mem 0x30000000 b /dev/mem opened. Memory mapped at address 0x40007000.
