Re: TI1225 on MIPS...

Greetings David.

I have made significant progress on the TI1225 adapter with my
MIPS board. I succesfully got a 3Com 3C589D adapter working,
now I am fighting with a compact flash card. Here is what I have
so far.

Below are the important entries from /proc:

    bash-2.05# cat /proc/ioports
    00001000-01000fff : PCI I/O space
      00001000-00004fff : PCI CardBus #01
      00005000-000050ff : PCI CardBus #01
      00005400-000054ff : PCI CardBus #05
      00005800-000058ff : PCI CardBus #05
    06020280-0602029f : eth0
    bash-2.05# cat /proc/iomem
    00000000-07ffffff : System RAM
      00100000-00309a87 : Kernel code
      00328000-00369fff : Kernel data
    08000000-0fffffff : PCI Memory space
      08001000-08400fff : PCI CardBus #01
      08402000-08801fff : PCI CardBus #05

and my /etc/pcmcia/config.opts file looks like:

    exclude port 0x0000-0x58ff
    include port 0x5900-0x61ff
    include memory 0x08802000-0x08809fff

    module "ide-cs" opts "pc_debug=1 irq_list=58,59"

When I insert the compact flash card, my board freezes for
a bit, I then eject and then reinsert the card and after a
few seconds I get these messages:

    hda: no response (status = 0xff)
    ide_cs: ide_register() at 0x5900 & 0x590e, irq 58 failed

Next, I do a 'dump_cis' and get the following:

    Socket 0:
      no CIS present
    Socket 1:

      cftable_entry 0x03
        Vcc Vnom 3300mV Ipeak 45mA
      cftable_entry 0x07

I instrumented 'ide-cs.c' a little bit and it appeared that things were
proceeding in the proper order:

    10:41:43 10 cardmgr[93]: socket 1: ATA/IDE Fixed Disk
    10:41:43 10 kernel: pcmcia_request_io
    10:41:43 10 kernel: pcmcia_request_irq
    10:41:43 10 kernel: pcmcia_request_configuration
    10:41:43 10 kernel: write_cis_mem: 0xa8802206 len=1
    10:41:43 10 kernel: write_cis_mem: 0xa8802200 len=1
    10:41:43 10 kernel: write_cis_mem: 0xa8802202 len=1
    10:41:43 10 kernel: write_cis_mem: 0xa8802204 len=1
    10:41:43 10 kernel: pcmcia_request_configuration: Configure I/O windows
    10:41:43 10 kernel: pcmcia_request_configuration: iomap.start=0x00006000
    10:41:43 10 kernel: pcmcia_request_configuration: iomap.stop=0x0000600f
    10:45:18 10 kernel: pcmcia_release_io
    10:45:18 10 kernel: pcmcia_release_irq
    10:45:34 10 kernel: hda: no response (status = 0xff)

I am baffled as to why the IRQ and I/O port addresses are not matching
what I thought was being configured. I will now go back and instrument
the IO and IRQ request functions and see what is going on. Can you shed
some light on my stupidity? Thanks.
