Hi! i use the P89c669 microcontroller,can i erase and reprogram the hole flash memory by using the IAP method.now i try this and i am not able to do this in lower memory area [from address 0x0000].i can do this in only above the 8K memory. Thank you! regards, K.T.Venkatesh.
I haven't worked with your specific chip, but what precautions have you taken to not overwrite your own program? The program performing the IAP have to reside somewhere too...
Then IAP is applicable for only specific memory areas!am i right? Regards, K.T.Venkatesh.
since it is done by FlashMagic, why not go here forum.flashmagictool.com/index.php

Hi! But flash magic supports ISP programming only.actually my requirment is download the program to the P89c669 throug the SPI interface,thats way i select the IAP method. Regards, K.T.Venkatesh.
