Hello All

I have been trying to build RTEMS-4.10.2 for mvme 2304 CPU.

First I tried to run an EPICS application but failed. I was advised to try first the example application which I tried today.

After configuring the CPU with NIOT command of PPC1BUG and running the NBO command for network booting with the file hello.exe, it loaded the file from tftp server but execution returned in error.

I am pasting below all that was on the hyperterminal screen (PPC1BUG commands and messages)

I need guidance to find what could be the possible problem there?

While installing the tool-chain, gcc and rtems I did not face any problem or error. I had been installing it successfully many times before this one, so I am confident about RTEMS and Toolchain. However I need expert opinion.

This time while installing RTEMS for MVME2304, I just copied the files for MVME2307 with the names of MVME2304 to get the bsp supported.

Please guide me if I was right in doing that.
