I have code that calculates the CRC of Flash at power up, that works
fine on the AT90CAN64 part.
When I move the CRC function to the Tiny88 it does not work.
To me it looks like in the generated code _data_load_end is stuck at
0x0100 (256),
but the map and symbol file show reasonable values:
project.map file:
0x0000034a __data_load_start = LOADADDR (.data)
0x0000034a __data_load_end =
(__data_load_start + SIZEOF (.data))
project.sym file:
00000346 W exit
00000348 t __stop_program
0000034a A __data_load_end
0000034a A __data_load_start
0000034a T _etext
00800100 B __bss_start
00800100 T __data_end
00800100 T __data_start
project.lss file:
uint16_t flash_end_u16 = (uint16_t) &(__data_load_end[0]);
13e: 00 e0 ldi r16, 0x00 ; 0
140: 11 e0 ldi r17, 0x01 ; 1
What is going on here?
This is with avr-gcc (WinAVR 20081205) 4.3.2.
