Hi all..

Can anyone provide me details about the coding for compact flash in mpc8540.

How to start the coding ?

I have collected some information based on toshiba's technical note {which describes Compact Flash support for 8260}

But i need help regarding coding..

How to proceed..

Sudhakar:

As I _*PREVIOUSLY*_explained to you off list, with the Toshiba app note, you need only

add CFG_CMD_IDE to your CONFIG_COMMANDS

and its associated parameters (this uses cmd_ide.c)

for example:

#define CFG_ATA_BASE_ADDR 0xF0000000 #define CFG_ATA_IDE0_OFFSET 0x0000 #define CFG_ATA_DATA_OFFSET 0x0000 /* Offset for data I/O */ #define CFG_ATA_REG_OFFSET 0x0000 /* Offset for normal register accesses* #define CFG_ATA_STRIDE 2 /* Directly connected CF, needs a stride */

The above values MUST be adapted for your platform. If you have the CF connected correctly it just works.

Please, READ the code, it exists, and works.
