Nor

一 打开nor参数相关宏​

文件位于bootloader/uboot-x2000/include/configs/ad100_base_common.h

1

二 添加nor相关参数及分区信息​

文件位于bootloader/uboot-x2000/tools/ingenic-tools/sfc_builtin_params/nor_device.c

以开发板flash GD25B512ME为例添加，打开烧录工具查看对应flash信息

2

将nor相关参数写入nor_device.c

struct spi_nor_info builtin_spi_nor_info = {

    .name = "GD25B512ME",
    .id = 0xC8471A,

    .read_standard    = CMD_INFO(0x13, 0, 4, 0), //对应单线读
    .read_quad    = CMD_INFO(0x6c, 8, 4, 5),    //对应四线读
    .write_standard   = CMD_INFO(0x12, 0, 4, 0), //对应单线写
    .write_quad   = CMD_INFO(0x34, 0, 4, 5),    //对应四线写
    .sector_erase     = CMD_INFO(0x5c, 0, 4, 0), //对应扇区擦除
    .wr_en        = CMD_INFO(0x06, 0, 0, 0),   //对应写使能
    .en4byte      = CMD_INFO(0xb7, 0, 0, 0), //对应4字节地址模式
    .quad_set     = ST_INFO(-1, -1, -1, -1, -1, -1), //对应设置四线
    .quad_get     = ST_INFO(-1, -1, -1, -1, -1, -1), //对应获取四线
    .busy         = ST_INFO(0x05, 0, 1, 0, 1, 0),//对应获取WIP状态

    .tCHSH = 5,
    .tSLCH = 5,
    .tSHSL_RD = 20,
    .tSHSL_WR = 40,

    .chip_size = 67108864,
    .page_size = 256,
    .erase_size = 32768,

    .quad_ops_mode = 0,
    .addr_ops_mode = 0,
    .chip_erase_cmd = 0x60,


#ifdef CONFIG_INGENIC_XXXXX
    //add your flash

};

将分区信息写入nor_device.c

struct norflash_partitions builtin_norflash_partitions = {

    /* max 10 partitions*/
    .num_partition_info = 4,     //根据分区个数来修改

    .nor_partition = {

        [0].name = "uboot",
        [0].offset = 0x0,
        [0].size =   0x40000,
        [0].mask_flags = NORFLASH_PART_RW,
        [0].manager_mode = MTD_MODE,

        [1].name = "kernel",
        [1].offset = 0x40000,
        [1].size =   0x600000,
        [1].mask_flags = NORFLASH_PART_RW,
        [1].manager_mode = MTD_MODE,

        [2].name = "rootfs",
        [2].offset = 0x640000,
        [2].size = 0x1000000,
        [2].mask_flags = NORFLASH_PART_RW,
        [2].manager_mode = MTD_MODE,

        [3].name = "userdata",
        [3].offset = 0x1640000,
        [3].size = 0x1000000,
        [3].mask_flags = NORFLASH_PART_RW,
        [3].manager_mode = MTD_MODE,
    },
};


/*
 * params: private params
 */
private_params_t builtin_private_params = {
    .fs_erase_size = 32768,  //文件系统擦除块大小
    .uk_quad = 1,
};

#define NORFLASH_PART_RW    0
#define NORFLASH_PART_WO    1
#define NORFLASH_PART_RO    2

#define MTD_MODE                0x0     //use mtd mode, erase partition when write
#define MTD_D_MODE              0x2     //use mtd dynamic mode, erase block_size when write
#define UBI_MANAGER             0x1

分区个数不能超过十个, 如需要大于十则要修改代码

使用到rtos, 修改文件位置freertos/xburst2/soc-ad100/sfc_nor_params.h

linux 修改uboot 及kernel :

uboot文件位于bootloader/uboot-x2000/arch/mips/include/asm/arch-ad100/spinor.h

kernel文件位于kernel/kernel/module_drivers/drivers/mtd/devices/ingenic_sfc_v2/spinor.h

三 编译​

修改后重新编译uboot

bhu@bhu-PC:~/ad101/build$ make uboot

生成的uboot, 可以对比下, 与屏蔽掉第一章节打开的宏后, 烧录工具合并镜像功能打包出来的uboot进行对比
