hi ali u can use your external flash memory in both two modes. 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 program.for example: in command file: interrupt_vectors_manifest: 0x000FF80 PAGE 0 { your code.obj } and in your code: reset FBD boot routine area and in boot routin area: ,,,,,,,,, //some initial code ; begin _c_int00 NOP NOP FBD _c_int00 ; SSBX XF NOP NOP i hope that it will be usefull for u. regards mohammad mirza alivandi --- ali rezaiye <> wrote: > hi all. > can i use external flash memory in microcomputer > mode > by C5402 and in microprocessor mode, should i write > it's bootloader program myself? > thank you. > __________________________________ > _____________________________________ > Note: If you do a simple "reply" with your email > client, only the author of this message will receive > your answer.
