Hi Friends,
I have my custom board with MCF5329 processor and M29W128GL (16MB NOR). I have LTIB package from freescale of M5329EVB board. I am using this package and modified according M29W128GL NOR. Like
* FLASH organization */ #define CONFIG_SYS_FLASH_CFI #ifdef CONFIG_SYS_FLASH_CFI # define CONFIG_FLASH_CFI_DRIVER 1 # define CONFIG_SYS_FLASH_SIZE 0x1000000 /* Max size that the board might have */ # define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_16BIT # define CONFIG_SYS_MAX_FLASH_BANKS 1 /* max number of memory banks */ # define CONFIG_SYS_MAX_FLASH_SECT 137 /* max number of sectors on one chip */ # define CONFIG_SYS_FLASH_PROTECTION /* "Real" (hardware) sectors protection */ #endif
And Enviroment Configuration:
#define CONFIG_SYS_FLASH_BASE CONFIG_SYS_CS0_BASE
/* Configuration for environment * Environment is embedded in u-boot in the second sector of the flash */ #define CONFIG_ENV_OFFSET 0x40000 #define CONFIG_ENV_SECT_SIZE 0x20000 #define CONFIG_ENV_SIZE 0x2000 #define CONFIG_ENV_IS_IN_FLASH 1
And U-boot output after flash using JTAG:
