2.3 cfi shadow内存分配 为了支持跨DSO cfi检查,引入了cfi shadow,CFI shadow可以快速查找一个库的_cfi_check函数地址。用于完成virtual / indirect call targets to __cfi_check functions映射。 CFI shadow is effectively a very fast and specialized implementation of dladdr: given an address that belongs to ...

CFI（Chip Identification Format）驱动介绍如下：在读写操作中，需要按照总线位宽进行读写，注意与FLASH芯片位宽的区别（例如背靠背）。程序访问的地址与FLASH芯片地址引脚得到的值不同，例如16位的FLASH芯片，CPU视作0x00和0x01为不同字节，而引脚得到的都是0，指向FLASH第一个字。地址总线的bit0可能悬空...

For this check to work, the code must always respect the function signature when using function pointer, the function must be defined at compile time, and be compiled with link-time optimization. This rules out, for example, shared libraries that are dynamically loaded (given that functions are...

此外,NOR还支持更多高级命令(Blank Check、security/protect相关,lower power相关等),那些命令因Device而异,不是本文讨论重点。 除了读写擦这三个最基本命令外,还有一个Data Polling机制也非常常用,这个机制用于获取命令(主要是Program/Erase)执行状态与结果,当Program/Erase命令发给NOR device之后,NOR device是通过DQ[...
