Hi Yuke,
Sorry to ask the stupid question. I did study the RTEMS for a while and am sure the tool set are correct (from ftp://www.rtems.com), otherwise they will not build RTEMS. All the tools and development are done in linux (RHLE5). I just got this board using U-boot and not sure about it. David's manual help a lot. Thanks.
Its not that the questions are stupid, its that they lack information sufficient to help you. For example, the toolset ... readers of the list are busy, so expecting us to follow links and try to interpret which toolset you have installed is not going to happen. Its better to say, "I got the tool from this link ...' and it provided powerpc-linux-gcc version XXX, etc., and then what you've managed to succeed to do with the tools.
You say that the development is done with RHLE5, but then that a .exe is created. That seems to be a conflicting statement. Perhaps you could explain ... are you running the RTEMs tools under Wine??
Anyway, a good suggestion is to install ELDK and rebuild U-Boot and update it, even get Linux booted. It may not be your main goal, but consider it educational :)
Cheers, Dave
