I have an application where the user will update a data array on the host side. I then have a program that will convert the new data to intel hex. I want then to then reflash this data into my AVR.
I am using an AT90USB1286. My program is small and uses less than 25% of the AVR's flash memory. In my C code I have hard coded the location of the data:
Now if I paste my data values at the bottom of the hex file for the main code it works fine:
If I try to flash just the last 3 lines of the file listed above, things dont work.
The original program is lost and nothing seems to work.
Suggestions?

Code:
// Sample code to test idea
#define FLASHADDR 0x3000
for (i=0; i<50; i++) {
data = pgm_read_byte(FLASHADDR + i);
pchar(data)
