Re: Re: at91rm9200 ide driver for harddis k

I followed your advice, add "#define DEBUG" on the very top of drivers/ide/ide.c
anddrivers/ide/ide-probe.c , system run with information as follows:
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx
multiIO: IDE driver, (c) 2006 imc Measurement & Control
IDE: phys mem : 40000000...40000200 (size 0200)
probing for hda: present=0, media=32, probetype=ATA
probing for hda: present=0, media=32, probetype=ATAPI
probing for hdb: present=0, media=32, probetype=ATA
probing for hdb: present=0, media=32, probetype=ATAPI

I use PD23 pin as the ide irq line, so in linux-2.6.15 , its irq no is AT91_PIN_PD23. 
Does this cause problem?
In your codes sent to me, you did not configure the pin of AT91C_ID_IRQ5 for irq5, why it worked well?
Best regards.

If that's realy all you see then probably not!
I compiled it as a kernel module (but that doesn't matter) and get:

~ # hdd start
multiIO: IDE driver, (c) 2006 imc Measurement & Control
IDE: phys mem : 30040000...30040200 (size 0200)
hda: probing with STATUS(0x50) instead of ALTSTATUS(0x0a)
hda: TOSHIBA MK2023GAS, ATA DISK drive
irq30: nobody cared
ide0 at 0xc385e000-0xc385e007,0xc385e010 on irq 30
hda: max request size: 128KiB
hda: 39070080 sectors (20003 MB), CHS=38760/16/63
hda: cache flushes supported
 hda: hda1
...

Put a "#define DEBUG" on the very top of drivers/ide/ide.c and
drivers/ide/ide-probe.c and examine the output.
