Hello,all: I want to port the FatFs written by ELM Chan to keil for my AT91SAM7X demo board,but when I use f_open to open a file,it reset to DAbt_Handler B DAbt_Handler
the cause for it is the code in f_open() #define LD_WORD(ptr) (WORD)(*(WORD*)(BYTE*)(ptr))
Any suggestion? Thanks!
are you sure BPB_BytsPerSec's value is valid? a data abort exception is raised when an instruction attempts to access data memory without the correct access permissions.
