Hi Yasushi

I tried both with and without flthdr -z and I always obtain:

bin/agetty:   data
bin/busybox:  data
bin/cat:      data
     :
     :

I also tried without using flthdr at all, but I always obtain the same 
messages.

Sob, sigh :-(

my mb-gcc -v is:
Reading specs from 
/home/edasrv/ric/pizzamig/prj/mb-uclinux/experimental/toolchain/bin/../lib/gcc-lib/microblaze/2.95.3-4/specs
gcc version 2.95.3-4 Xilinx EDK 6.1 Build EDK_G.11

I'm using the last toolchain I find on John's site 
(microblaze-elf-tools-20040315.tar.gz) and I'm currently using the 
latest cvs updated uCL-dist....

cheers,
