1.When the program runs to eee Initialization function "FLASH_DRV_DEFlashPartition➡FLASH_DRV_CommandSequence",mcu will reset.Reset source is "LOCK UP".I used the "step over". 2.Before mcu reset, I used the "step into" to run "FLASH_DRV_CommandSequence".The program will run normally ...
It goes inside FLASH_DRV_EraseAllBlock function, then FLASH_DRV_CommandSequence, and at the end of the function throw a <signal handler called>() at 0xfffffff9 Which give me on View Disassembly ( i dunno if it's help) fffffff1: movs r0, r0 fffffff3: movs r0, r0 fffffff5:...
2. 暂停Flash扇区擦除(sector erase)的方法是在 FLASH_DRV_EraseSector()函数的Callback回调函数中,调用FLASH_DRV_EraseSuspend()函数,并确保其运行在不同的RWW分区或者remap到SRAM中运行; 3.FLASH_DRV_CommandSequence(),FLASH_DRV_EraseSuspend()和FLASH_DRV_EraseResume()必须运行在SRAM中(通过热map实现)或则不...

init_sequence是一个函数指针数组,数组中存储了很多个函数指针,这些指向指向的函数都是init_fnc_t类型(特征是接收参数是void类型,返回值是int)。 init_sequence在定义时就同时给了初始化,初始化的函数指针都是一些函数名。 init_fnc_ptr是一个二重函数指针,可以指向init_sequence这个函数指针数组。 用for循环肯定是...
