At some point flash's EF_ERASE_MIN_SIZE may become so big, * and you want to keep ENV size smaller. To do it you must define ENV_USER_SETTING_SIZE for ENV. * @note ENV area size has some limitations in different modes. * 1.Normal mode: no limitations * 2.Wear leveling mode: system section will used a flash section and the data section will use at least 2 flash sections * 3.Power fail safeguard mode: ENV area will has a backup. It is twice as normal mode. * 4.Wear leveling and power fail safeguard mode: The required capacity will be 2 times the total capacity in wear leveling mode. * For example: * The EF_ERASE_MIN_SIZE is 128K and the ENV_USER_SETTING_SIZE: 2K. The ENV_AREA_SIZE in different mode you can define * 1.Normal mode: 1*EF_ERASE_MIN_SIZE * 2.Wear leveling mode: 3*EF_ERASE_MIN_SIZE (It has 2 data section to store ENV. So ENV can erase at least 200,000 times) * 3.Power fail safeguard mode: 2*EF_ERASE_MIN_SIZE * 4.Wear leveling and power fail safeguard mode: 6*EF_ERASE_MIN_SIZE * @note the log area size must be more than twice of EF_ERASE_MIN_SIZE */ /* backup area start address */ #define EF_START_ADDR (FLASH_BASE + EF_ERASE_MIN_SIZE * EF_ERASE_MIN_SIZE_PAGE * (EF_ERASE_MIN_SIZE_SECTOR + 1)) /* @note you must define it for a value */ /* the user setting size of ENV, must be word alignment */ #define ENV_USER_SETTING_SIZE (EF_ERASE_MIN_SIZE * EF_ERASE_MIN_SIZE_PAGE) /* @note you must define it for a value if you used ENV */ /* ENV area total bytes size in normal mode. */ #ifndef EF_ENV_USING_PFS_MODE #ifndef EF_ENV_USING_WL_MODE /* ENV area total bytes size in normal mode. */ #define ENV_AREA_SIZE (1 * EF_ERASE_MIN_SIZE * EF_ERASE_MIN_SIZE_PAGE) /* 4K */ #else /* ENV area total bytes size in wear leveling mode. */ #define ENV_AREA_SIZE (3 * EF_ERASE_MIN_SIZE * EF_ERASE_MIN_SIZE_PAGE) /* 12K */ #endif #else #ifndef EF_ENV_USING_WL_MODE /* ENV area total bytes size in power fail safeguard mode. */ #define ENV_AREA_SIZE (2 * EF_ERASE_MIN_SIZE * EF_ERASE_MIN_SIZE_PAGE) /* 8K */ #else /* ENV area total bytes size in wear leveling and power fail safeguard mode. */ #define ENV_AREA_SIZE (6 * EF_ERASE_MIN_SIZE * EF_ERASE_MIN_SIZE_PAGE) /* 24K */ #endif #endif /* saved log area size */ // #define LOG_AREA_SIZE /* @note you must define it for a value if you used log */ /* print debug information of flash */ #define PRINT_DEBUG #endif /* EF_CFG_H_ */
