按照上面帖子中的说法，以下理解是否正确？

Fapi_issueBankEraseCommand函数会擦除pu32StartAddress所在Bank的指定扇区，OSectorMask指定该Bank中不需要擦除的扇区的掩码。

也就是说使用形如 Bzero_SectorXX_start的参数，都是擦除Bank0中扇区，并且OSectorMask能指定是否擦除对应的Sector0~Sector15

使用形如 Bone_SectorXX_start的参数，都是擦除Bank1中扇区。

如果上述无误，官方例子中的：

u32CurrentAddress = Bzero_Sector8_start; 是否可以改成

u32CurrentAddress = Bzero_Sector0_start;

或

u32CurrentAddress = Bzero_Sector15_start;

请指教！

你好，

或

u32CurrentAddress = Bzero_Sector15_start;

应该是可以的。
