u can use your external flash memory in both two
important note that u should think about it, is the
changes on the memory map,u can also change your MP/MC
flag during running your program.
about bootloader as you know @ hardreset our program
counter will be set by FF80 and it is our interrupt
vector address,so usually we define a farbaranch to
our boot routines there and in the end of boot
routines we will branch to begining of our main
in command file:
interrupt_vectors_manifest: 0x000FF80 PAGE 0
and in your code:
reset FBD boot routine area
and in boot routin area:
,,,,,,,,, //some initial code
; begin _c_int00
; SSBX XF
i hope that it will be usefull for u.
