Alternative SDRAM settings:

|
|
|
#define SDRAM_MODE 0x018D0000
|
|
#define SDRAM_EMODE 0x40090000
|
|
#define SDRAM_CONTROL 0x715f0f00
|
|
#define SDRAM_CONFIG1 0x73722930
|

#define SDRAM_CONFIG2 0x47770000
|

|
/* Settings for XLB = 99 MHz */
|
|
#define SDRAM_MODE 0x008D0000
|
|
#define SDRAM_EMODE 0x40090000

#define SDRAM_CONTROL 0x714b0f00

#define SDRAM_CONFIG1 0x63611730

The board ships default with the environment in EEPROM
|
|
Moving the environment to flash can be more reliable
|

|

#define CONFIG_ENV_IS_IN_FLASH 1

|
#define CONFIG_ENV_ADDR (CONFIG_SYS_FLASH_BASE + 0xfe0000)
|
|
#define CONFIG_ENV_SIZE 0x20000

#define CONFIG_ENV_SECT_SIZE 0x20000
