FlashSize表示内部flash的大小,也是固化在芯片内部的。 手册上讲的ChipID的基地址是0x1FFF7A10,ChipSize的基地址也是0x1FFF7A10。肯定是不对的 谷歌了半天才发现真正的ChipSize地址0x1FFF7A20。知道了地址,直接读取地址中的数据就OK了。操作相当简单 读取FlashSize uint16_t

The flash size is the second part (size) of the first reg value, not the first part (address) of a nonexistent second reg value. This was introduced in #68274, and I don't understand how it has eve...
首先声明,手册上给出的FlashSize地址是错误的,正确的应该是0x1FFF7A20,取高16位。确切说应该是(0x1FFF7A23,0x1FFF7A22两个字节), 芯片的这96位ID是产品唯一身份标识。可以从特定的寄存器中读出来。FlashSize表示内部flash的大小,也是固化在芯片内部的。
