[avr-gcc-list] problems with linker

[Steve Joiner]

Hello,

I'm trying to get my avr build environment working.  I've got the
latest snapshots of binutils and gcc (binutils-020924 and
gcc-20020923).  I also grabbed avr-libc from CVS today (9/24).  I
followed the instructions at

http://savannah.nongnu.org/download/avr-libc/doc/avr-libc-user-manual/install_tools.html

and was able to build and install everything without any problems. 
I've got a simple program, foo.c that I'm trying to compile for the
at90s4433.  I issue the following command:

avr-gcc -g -mmcu=at90s4433 -Wl,-Map,foo.map foo.c

It builds successfully, but the start of the map file looks like this:

Archive member included because of file (symbol)

/usr/local/atmel/lib/gcc-lib/avr/3.3/libgcc.a(_copy_data.o)
                              /tmp/ccgWgtvZ.o (__do_copy_data)
/usr/local/atmel/lib/gcc-lib/avr/3.3/libgcc.a(_clear_bss.o)
                              /tmp/ccgWgtvZ.o (__do_clear_bss)

Memory Configuration

Name             Origin             Length             Attributes
text             0x00000000         0x00002000         xr
data             0x00800060         0x0000ffa0         rw !x
eeprom           0x00810000         0x00010000         rw !x
*default*        0x00000000         0xffffffff

Linker script and memory map

LOAD
/usr/local/atmel/lib/gcc-lib/avr/3.3/../../../../avr/lib/crts4433.o
LOAD /tmp/ccgWgtvZ.o
LOAD /usr/local/atmel/lib/gcc-lib/avr/3.3/libgcc.a
LOAD /usr/local/atmel/lib/gcc-lib/avr/3.3/../../../../avr/lib/libc.a
LOAD /usr/local/atmel/lib/gcc-lib/avr/3.3/libgcc.a

This seems wrong to me because it is reporting the length of the text
section as 0x2000 and the length of the data section as 0xffa0. 
According to the data sheet, they should be 0x800 and 0xf0,
respectively.  The eeprom length looks wrong too.

Can anyone tell me what I'm doing wrong here?

Thanks,
Steve
