FR8000操作flash

[Mars]

FR800X系列的型号不一样，flash的大小也不一样；
如果使用的是FR8008GP，8M的flash需要app_config.h里面更新这段代码

// <h> FLASH Configuration
// <o> FLASH_CAPACITY
// <i> Internal Flash capacity selection, Default: 4Mb
// <0x01000000=> 8Mb
// <0x00080000=> 4Mb
// <0x00040000=> 2Mb

#define FLASH_CAPACITY 0x01000000

#if FLASH_CAPACITY == 0x00080000
#define BLE_STACK_KEY_STORAGE_OFFSET 0x7F000
#define BLE_BONDING_INFO_SAVE_ADDR 0x7D000
#define BLE_REMOTE_SERVICE_SAVE_ADDR 0x7E000
#elif FLASH_CAPACITY == 0x00040000
#define BLE_STACK_KEY_STORAGE_OFFSET 0x3F000
#define BLE_BONDING_INFO_SAVE_ADDR 0x3D000
#define BLE_REMOTE_SERVICE_SAVE_ADDR 0x3E000

#define BLE_STACK_KEY_STORAGE_OFFSET 0xFFF000

#define BLE_REMOTE_SERVICE_SAVE_ADDR 0xFFE000
#else
#error "flash capacity configuration error!"
#endif //FOR_2M_FLASH

关于FR8008GP的flash分配，看了“FR8008XP Datasheet”、“FR8000 Specification”和“FR8000 SDK用户手册”这几个文件，发现表述的flash不太一样。
这里说挂载的flash是64M的。

但这里说最大支持的是16M

也和存储程序的flash不同

我想问一下，这几个flash之间的关系是什么，指向的物理地址是相同的吗，文中的 “FR8008GP为8M的flash”又是属于什么部分的。

@emrof 如果你的芯片flash是8M的指向的起始地址也是0x1000 0000

[010101]

@mars FR8008GP 的flash能读 但是擦除和写不行
