Flash Transport Layer Usage

group FTL_USAGE

Flash Transport Layer Sample.

• Ext FTL module access.

  • step1: Init an ext FTL module.

  • step2: Save data to the ext FTL module.

  • step3: Load data from the ext FTL module.

  • Sample code:

    #define EXT_FTL_NAME "TEST_FTL"
    #define EXT_FTL_LOGIC_SIZE     (0x1000)
    #define EXT_FTL_BLOCK_SIZE     (64)
    void ftl_ext_module_demo(void)
    {
        // Init an ext FTL module
        ftl_init_module(EXT_FTL_NAME, EXT_FTL_LOGIC_SIZE, EXT_FTL_BLOCK_SIZE);
        // Save data
        uint8_t data_buf[EXT_FTL_BLOCK_SIZE];
        memset(data_buf, 0x5A, EXT_FTL_BLOCK_SIZE);
        uint16_t test_offset = 0x800;
        uint32_t ret = ftl_save_to_module(EXT_FTL_NAME, data_buf, test_offset, EXT_FTL_BLOCK_SIZE);
        if (ret != ESUCCESS)
        {
            //save data error
            return;
        }
        //Load data
        uint8_t read_buf[EXT_FTL_BLOCK_SIZE];
        ret = ftl_load_from_module(EXT_FTL_NAME, read_buf, test_offset, EXT_FTL_BLOCK_SIZE);
        if (ret != ESUCCESS)
        {
            //load data error
            return;
        }
    }
