Bootloader:     file format elf32-avr

Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .bootloadertrampoline 0000001e  00020000  00020000  00000094  2**0

                  CONTENTS, READONLY, DEBUGGING

However, since I'm writing a binary file directly (which does not
include addresses), the data should be automatically relocated to
0x20000, shouldn't it?

Kind regards,
