Question: Partial card functionality, memory port probs?

First, vital statistics: Linux version 2.2.13 Linux PCMCIA Card Services 3.1.10 ... Intel i82365sl A step ISA-to-PCMCIA at port 0x3e0 ofs 0x00 host opts [0]: none host opts [1]: none ISA irqs (default) = 3,5,7,9,10,12,14,15 polling interval = 1000 ms cs: IO port probe 0x1000-0x17ff: excluding 0x11f0-0x1207 0x12f8-0x1307 0x1378-0x1387 0x13f0-0x13ff cs: IO port probe 0x0100-0x04ff: excluding 0x1f0-0x207 0x378-0x387 0x3f0-0x3ff cs: IO port probe 0x0a00-0x0aff: excluding 0xaf8-0xaff cs: memory probe 0x0d0000-0x0dffff: clean. And: swlr# cat /proc/bus/pccard/memory 000d0000-000d0fff : card services With that out of the way, I have an interesting problem with multiple cards. The hardware is an embedded system board with an onboard PCMCIA controller. The processor is an AMD Elan SC400 (http://www.amd.com/products/lpd/elan400/21026b.html) that has PCMCIA functionality 'built-in'. I've had 3c589_cs working on older kernel versions and older pcmcia-cs versions, but with my existing software, I have a problem running 3c589_cs, and more specifically Elmer Joandi's Aironet 4800 driver. I have never been able to make the Aironet 4800 card work on this hardware, no matter what software versions I've used. With both cards/drivers, the card is found, but the driver has a problem doing anything with it. I can configure it with an address, and try pinging, but I get errors, such as these with 3c589: eth1: 3Com 3c589, io 0x310, irq 3, hw_addr FF:FF:FF:F9:FF:FA 32K FIFO split 3:5 Rx:Tx, auto xcvr eth1: interrupt(s) dropped! eth1: interrupt(s) dropped! eth1: interrupt(s) dropped! eth1: interrupt(s) dropped! eth1: command 0x5800 did not complete! eth1: command 0x5800 did not complete! eth1: command 0x5800 did not complete! eth1: interrupt(s) dropped! .... and so on. Note the hw_addr - probably bad! This is the same thing that happens with the 4800 card, I get a bogus MAC address, and various error messages when I try to read/write to it. Pulling the card I'm using and trying to load the drivers produces the logical response - card not found. I tried loading X driver for Y card to see if that was a problem/possibility, and that produced the logical response as well - wrong driver for the card. It seems that the cards are being seen and identified, and I can "kind of" communicate with them, but not all the way. Memory addresses 0xd0000-0xdffff are shown free by the system, and the probe, and I have verified vigorously with the hardware manufacturer that this is the case. Anyone have any ideas?

Maybe an IO port issue? Re: Question: Partial card functionality, memory port probs? (Ben hoyt) Date: 2000, Feb 26 From: David Hinds <dhinds@pcmcia.sourceforge.org>

I think I'd reclassify this as a development issue, just because it is an oddball platform... (and one that I didn't know worked at all until now) The first thought I have is that it would be very useful to determine which PCMCIA releases worked, and when problems started to appear. And compare the startup messages from the working configuration with the current one, if that is possible. I take it that you didn't need to use any out-of-the-ordinary settings with the older drivers? I don't know anything about Elmer Joandi's Aironet driver. The current PCMCIA release includes Ben Reed's driver for these cards. > eth1: 3Com 3c589, io 0x310, irq 3, hw_addr FF:FF:FF:F9:FF:FA My first guess here would be that maybe you're seeing an IO port conflict. The hw_addr is read using IO ports. -- Dave
