Loading RTEMS application on MVME162

[Eric Norum]

Did you download to location 0x20000 and start execution at that point?  It looks like that is where the linker script is placing the beginning of the text (code) section.
I no longer have my MVME167Bug manuals so I can't describe exactly how to specify the download location.
Also, you should download the .ralf file not the .elf file.
