[avr-gcc-list] .eeprom section overlapping bootloader linker error

[Spencer Hollingum]

When my eeprom section gets above a certain size I get a linker error. I am
using an assembler bootloader located at 0x1e00. 
Error goes away if I reduce the eeprom or main code size, in which case
everyting works fine , main code and bootloader. 

Linker Error Message:-

C:\WinAVR\bin\..\lib\gcc-lib\avr\3.3\..\..\..\..\avr\bin\ld.exe: section
.eeprom 
[00001d0e -> 00001e00] overlaps section .bootloader [00001e00 -> 00001fb7] 
make: *** [main.elf] Error 1 

I am using the following linker flags 

LDFLAGS = -Wl,-Map=$(TARGET).map,--cref,--section-start=.bootloader=0x1e00 

Below is the map file with the section sizes reduced so that the linker
error does not occur.

The LMA of the .eeprom section is 0x1d0e which means if the .eeprom size
increases above 0xf2 bytes it will hit the bootloader at 0x1e00. The eeprom
and bootloader should be in different address spaces so there should be no
clash.

 

Target device is an ATmega8.

 

Any suggestions?

 

Thanks
