Hello Stanislaw,
i am working on custom board with AT91SAM9263, i am trying to start
communication with CompactFlash throught your kernel driver (true
ide mode). I have problem to connect CF to file to /dev directory.
After module load kernel prints message "ide0 at
0xc4866000-0xc4866007,0xc486e006 on irq 132" without some
identification in /dev/(hda). Can you help me, what can be wrong?
Wires connections betweent processor and CF should be ok.
I have these options in kernel:
CONFIG_IDE
CONFIG_IDE_GD
CONFIG_IDE_GD_ATA
CONFIG_IDE_TASK_IOCTL
CONFIG_IDE_PROC_FS
CONFIG_BLK_DEV_PLATFORM
CONFIG_BLK_DEV_IDE_AT91
CONFIG_IDE_TIMINGS is also needed, but this should be selected if
CONFIG_BLK_DEV_IDE_AT91 was chosen.
If there is no info in /proc/partitions, then disc was not detected.
It's hard to tell why without more verbose messages. Add
"EXTRA_CFLAGS += -DDEBUG" to drivers/ide/Makefile and provide full
dmesg output.

Hello,
i have only mtdblock0 in /proc/partitions (it is NAND), about CF is
nothing. There is my dmesg output, the important is on end of list.
