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.
