<----> Wow.  Thanks Chris, that makes a lot of sense, although I had no
idea
<----> that the SystemAce chip was quite so clever.  I take it that the
<----> bitstream in the .ace file is specially constructed by the tools
to
<----> do
<----> the DRAM download?  What is it that produces the text:
<----> loaded at:     00400000 004E21E4
<----> board data at: 004DF13C 004DF154
<----> relocated to:  00405660 00405678
<----> zimage at:     00405C25 004DE92F
<----> avail ram:     004E3000 04000000
<----> I have always assumed that it is a piece of software that does
this.
<----> Is
<----> that correct?

It must be xmd that display messages in its console. All displayed
address correspond to sections (see the linker file) for exemple txt if
for the code , bss is for data...
There is no code running on the powerpc during elf dowload.

<----> Thanks very much for replying, the information is really helpful.

kinds regards
