[avr-gcc-list] Can't debug bootloader in avrstudio (Vasil Atanasov) continue

[Vasil Atanasov]

Hello,
I will send all info about my problem

here is a simple program named boot2.c:

#include <avr/io.h>

void bootloader(void)   __attribute__ ((section (".bootldr")));

int main(void){

  bootloader();
return 0;
}

void bootloader(void)
{
  PORTA=0xaa;
}

my makefile do:

Compiling: boot2.c
avr-gcc -c -mmcu=atmega128 -I. -g -O0 -funsigned-char -funsigned-bitfields 
-fpack-struct -fshort-enums -Wall -Wstrict-prototypes -Wa,-adhlns=boot2.lst  
-std=gnu99 boot2.c -o boot2.o

-std=gnu99 boot2.o   --output boot2.elf -Wl,-Map=boot2.map,--cref 
-Wl,--section-start=.bootldr=0x1E000 -lm

Creating load file for Flash: boot2.hex
avr-objcopy -O ihex -R .eeprom boot2.elf boot2.hex

Creating load file for EEPROM: boot2.eep
avr-objcopy -j .eeprom --set-section-flags=.eeprom="alloc,load" \
--change-section-lma .eeprom=0 -O ihex boot2.elf boot2.eep

Creating Extended Listing: boot2.lss
avr-objdump -h -S boot2.elf > boot2.lss

Creating Symbol Table: boot2.sym
avr-nm -n boot2.elf > boot2.sym

after that I start make extcoff
Compiling: boot2.c

If i load boot2.hex then all code is ok, but in boot2.cof file on address F000 
is 0xffff

Thank you in advance
