RDA支持的FLASH型号列表“drv_spi_flash_table.h”
常用型号：
KH/MX 3206E KH/MX 3236F
华邦4M：W25Q32
关于写保护：
例如博雅FLASH BY25Q32BS 4M 写保护区域 62/63th。
配置文件如上图：
1、蓝色箭头“2”代表要写两个状态寄存器。
3、红色箭头表示，第一个状态寄存器的值。
3、粉色箭头表示，第二个状态寄存器的值。
SPEC 定义的状态寄存器如下：
SPEC：写保护配置如下：
RR8501.BIN结构
RR8501不同的MODEL经过压缩和加密
code.tmp.bin未经过加密，分析code.tmp.bin
UE打开
20 00 00 10 00 00 00 00 00 D0 07 00 F0 7B 01 00
BootSize = 0x07D000
SHARE DATA读写
tv_SaveFlashSetting()
mergedir/code.tmp.bin 压缩未加密文件的FLASH文件
mergedir/sfs/nvm.bin shareData数据文件，未加密、未压缩
数据克隆：DATA/ALL
APP_Clone_Backup_SystemData_To_USBBackup(CV_FM_DATA)
APP_Clone_Backup_FlashData_To_USBBackup(DataType_t DataType) //BACKUP_ROMBIN_DATA
中间件的读写： Cmd_FlashWrite(UINT32 destAddr, UINT32 srcAddr, UINT32 size)
中间件模块读写： Cmd_FlashModuleUpdate(INT8 * moduleName, INT8 * updateData, UINT32 updateSize)
通过ID寻找地址： Cmd_GetAddrAndSizeByFlashID(UINT8 flashID, UINT32 *pFlashAddr, UINT32 *pFlashSize)
shareData的读写：tv_SaveFlashSetting()
读写FLASH: spi_write_flash
更新POWER键：update_option_ir_power_key
SFS底层调用：spi_dmawrite(__u32 dest,__u32 src,__u32 size)
信号量的操作：VD_SEM_TAKE/VD_SEM_GIVE
设备读：Cmd_NVMRead(UINT8 eNvmID, UINT8 u8Compress, UINT32 u32Count, UINT8 *pu8Buffer)
设备写：Cmd_NVMWrite(UINT8 eNvmID, UINT8 u8Compress, UINT32 u32Count, UINT8 *pu8Buffer)
组件装载：AL_Setting_Reload(AL_SETTING_HANDLE handle, al_uint8 user_pref_id) //user_pref_id=0xff 装载整个设备到cache
读取默认值到cache：AL_Setting_ReadDefault(AL_SETTING_HANDLE handle,al_uint8 user_pref_id, const al_void *data)
读写内存：AL_Setting_Read()/AL_Setting_Write()
写FLASH：AL_Setting_Store()
AL_Setting_Store(APP_Data_UserSetting_Handle(), 0xFF, 0, sizeof(APP_SETTING_Storage_t)); //将cache所有数据写到FLASH
