As stated in the title,hard fault occurred when i try to read flash content. i was used "memcpy" function.and i tried myself function too,like this:
it was the same problem,when i used "Flash_read" function with parameter "Addr" was 0xFF000. but,it was no problem when parameter "Addr" was 0xFE000. i'd want to ask,whether this problem is caused by the security of flash sector?
