Easy Question, invalid ORG Range
PostPosted: Thu Sep 27, 2007 12:00 am     Reply with quote

I have CCS PCWH compiler 3.249. This is my code
#build(reset=0x0800, interrupt=0x808) // Necessary for Bootloader
#ORG 0x809,0x7FFF {} // Necessary for Bootloader

I have remapping memory space because I am using PICDEM FS 18F4550 development board. Reset vector is 800h, Interrupt vector is 808h, and the Program Memory goes from 800h to 7FFFh.


What would be an valid ORG range?

Your reset vector is at 0x800 but the #org starts at 0x809, fix this by changing the #org to start at 0x800.
