That is not the correct file to download to the uCdimm5282.  You need  
to download the <top>/bin/RTEMS-uC5282/test5282.boot file which should  
have been produced when you built the EPICS application.

Yes, and the required conversion should have been done.

=======================================================================
Here is a section of the README for the 5282:


Downloading the image to the board.
===================================
The bootable image is generated by the make-exe target in the bsp  
makefile. It
generates a simple stripped binary file which is downloaded over the  
ethernet
port into RAM then executed or programmed into flash memory.

1) Power up the uC5282 board. A dump of some memory maps is produced
   followed by a prompt.

2) (first time only)
   Set the uC5282 board Internet configuration:
        setenv IPADDR0 www.xxx.yyy.zzz      (Your board's address)
        setenv NETMASK ppp.qqq.rrr.sss      (Your local network address  
mask)
        setenv HOSTNAME somename            (Your board's name)

3) Type 'tftp<CR>'

4) Run 'tftp' on your host machine:
            tftp> binary
            tftp> connect www.xxx.yyy.zzz      (Your ucDIMM's address)
            tftp> put someFile.exe       (or someFile.boot if you're  
using the EPICS build system)

5) When the file has downloaded press the <ESC> key to terminate
   the uCDIMM tftp command.

6) Type 'goram<CR>' to start the downloaded program, or type  
'program<CR>'
to burn the code onto the uCDIMM flash.

EPICS Bootstrap Information
===========================
The EPICS startup code uses the following environment variables.  If an
optional environment variable is missing the value in parentheses will  
be used.
All Internet addresses must be given in 'dotted-decimal' format.
HWADDR0    - Ethernet hardware address.
IPADDR0    - Internet address (192.168.0.2).
NETMASK    - Local network address mask (255.255.252.0).
HOSTNAME   - Internet host name (iocNobody).
GATEWAY    - Internet address of gateway machine (NULL).
SERVER     - Internet address of NFS server (192.168.0.1).
NAMESERVER - Internet address of DNS server (SERVER).
DOMAIN     - DNS domain name (precompiled value from CONFIG_SITE).
NTPSERVER  - Internet address of NTP server (SERVER).
BOOTFILE   - Path to executable  
(epics/iocNobody/bin/RTEMS-uC5282/myApp.boot).
CMDLINE    - Path to startup script (epics/iocBoot/iocNobody/st.cmd).
NFSMOUNT   - NFS information: www.xxx.yyy.zzz:/remote/path /localpath
             A : can also be used to separate the remote and local  
paths.
             If NFSMOUNT is not set, SERVER will be used as the NFS  
server,
             and the remote and local paths will be taken from the first
             component of CMDLINE.  If CMDLINE does not begin with a /
             then '/tftpboot' is prepended to the remote path.  This  
allows
             a remote TFTP and NFS server to be handled transaparently.


The EPICS/RTEMS startup code can get the application startup scripts,  
'.db' and .'dbd' files from a flash in-memory filesystem image.  This  
allows an IOC to start up even if the network is not operational.  To  
create such an image simply tar up the required files and concatenate  
the tarball to the end of the application xxxxx.boot file, then  
transfer this image to the uCdimm flash memory.
Here's the script I use to perform this operation:
#!/bin/sh

set -ex

case "$#" in
    2)  name="$1" ; boot="$2" ;;
    *)  echo "Usage: $0 iocname boot_image" >&2 ; exit 1 ;;
esac

make -w

#
# Create a standalone (FLASH-based) IOC image
#
rm -rf tarball
mkdir tarball
cp -r db dbd tarball
sed -e  
'/epicsEnvSet[^A-Za-z0-9_]*TOP[^A-Za-z0-9_]/s/.*/epicsEnvSet(TOP,"\/")/ 
'  "iocBoot/${name}/envPaths" >tarball/envPaths
cp "iocBoot/${name}/st.cmd" tarball/st.cmd
(
cat "$boot"
(cd tarball ; tar cf - *)
) >"$boot:$name.image"
