The only change in 0.3.0 was that I added the target to build  binary
images,  too,  as some people asked for it to be able to download the
standalone examples over FTP.

The warning is normal and can be ignored.

The error message means that your version of "ppc_405-objcopy" is not
capable of reading  the  "hello_world.srec"  file  which  it  created
itself one step before.

Using the objcopy that comes with the ELDK I get:

	bash$ ppc_4xx-objcopy -O srec sched sched.srec
	bash$ ppc_4xx-objcopy -O binary hello_world.srec
	ppc_4xx-objcopy: hello_world.srec: File format not recognized
	bash$ 

And I get the same result with the native "objcopy" on any of the x86
Linux systems I was able to test (RH-7.1 to RH-9).

The only explanation I have is that your version of "ppc_405-objcopy"
is seriously broken.

Get yourself working tools. They are available for free.
