Hello,

on my custom board (PXA270) I have an IDE bus on DoM (mapped at 0x14400000) and an IDE bus on PCMCIA/CF (mapped at 0x20000000).

The DoM works while CF not. Here my output (please, note that I modified a bit the cmd_ide code in order to remove a device from Standby Mode):

equantum> pinit on

As you can see device 0 is correctly recognized, device 1 is not present, and device 2 doesn't work while device 3, which is not present, gives answers similar to device 2!

Device 2 is recognized but when the system tries to read the first sector it gets an error!

Note also that on Linux the CF works correctly, so the PCMCIA memory settings should be ok.

Here my board configuration:

#define CONFIG_PXA_PCMCIA 1
#define CONFIG_PXA_IDE 1

#define CFG_IDE_MAXBUS 2
#define CFG_IDE_MAXDEVICE 4

#define CONFIG_PCMCIA_SLOT_A 1 /* just to keep build system happy */

#define CFG_PCMCIA_MEM_ADDR 0x28000000
#define CFG_PCMCIA_MEM_SIZE 0x04000000

/* Memory configuration */

#define CFG_MECR_VAL            0x00000002
#define CFG_MCMEM0_VAL          0x00010504
#define CFG_MCMEM1_VAL          0x00014511
#define CFG_MCATT0_VAL          0x00010504
#define CFG_MCATT1_VAL          0x00014511
#define CFG_MCIO0_VAL           0x00004715
#define CFG_MCIO1_VAL           0x00014511

#define CFG_ATA_BASE_ADDR       0x14000000
#define CFG_ATA_IDE0_OFFSET     0x00400000      /* for the DOM */
#define CFG_ATA_IDE1_OFFSET     0x0c000000      /* for the PCMCIA */

/* IDE device 0 is accessed at 16-bit only (A0 is not used)
* while device 1 is accessed at 8-bit
*/
#define CFG_ATA_PORT_ADDR(dev, port) (((dev) < 1) ? ((port) << 1) : (port))

/* Offset for data I/O */
#define CFG_ATA_DATA_OFFSET 0x1f0

/* Offset for normal register accesses */
#define CFG_ATA_REG_OFFSET 0x1f0

/* Offset for alternate registers */
#define CFG_ATA_ALT_OFFSET 0x3f0

/* We have ATAPI support */
#define CONFIG_ATAPI 1

Does someone know what's wrong?

Thanks,

Rodolfo
