hi:

it seems that all others have no question or it is no other than me not to master this platform. I'm just trying to enrich it.

   my first question is: before main(), some function such as startup() called bootstrap or glue code is needed for preparation of main(). sometimes we also need bootloader which does update of users' code. so should I embrace bootsrap into bootloader. I am confused  about both.

 second, although the first and second vectors(both are RESET and COP RESET)  in interrupts vector table are fixed the address of a function, why must entry point of target setting be set as a function and what the result if both of them are referenced to two different functions ?

             sorry for such naive questions.

 

Best regards
