README.booting: written by S. Kate Feng <feng1@bnl.gov>, Aug. 28, 2007
|
|
|
|
The bootloader is adapted from Till Straumann's Generic Mini-loader,
|
|
which he wrote originally for the SVGM powerpc board.
|
|
The BSP is built and tested on the 4.7 CVS RTEMS release.
|
|
|
|
Booting requirement :
|
|
-------------------------
|
|
|
|
1) One needs to setup BOOTP/DHCP and TFTP servers and /etc/bootptab(BOOTP)
|
|
or /etc/dhcpd.conf (DHCP) properly to boot the system.
|
|
(Note : EPICS needs a NTP server).
|
|
|
|
2) Please copy the prebuilt RTEMS binary (e.g. misc/rtems5500-cexp.bin)
|
|
and perhaps others (e.g. misc/st.sys) to the /tftpboot/epics/hostname/bin/
|
|
directory or the TFTPBOOT one you specified in the 'tftpGet'
|
|
command of the boot script (as shown in the following example).
|
|
|
|
3) Example of the boot script setup carried out on the MOTLoad
|
|
command line :
|
|
|
|
MVME5500> gevEdit mot-script-boot
|
|
(Blank line terminates input.)
|
|
waitProbe
|
|
tftpGet -a4000000 -cxx.xx.xx.xx -sxx.xx.xx.xx -m255.255.254.0 -d/dev/enet0 -fepics/hostname/bin/rtems5500-cexp.bin
|
|
netShut
|
|
go -a4000000
|
|
|
|
|
|
Update Global Environment Area of NVRAM (Y/N) ? Y
|
|
MVME5500>
|
|
|
|
Note : (cxx.xx.xx.xx is the client IP address and
|
|
sxx.xx.xx.xx is the server IP address)
|
|
|
|
WARNING : It is extremely important that the MOTLoad "waitProbe", "netShut"
|
|
sequence be executed before booting RTEMS. Otherwise, network
|
|
interface interrupt handlers installed by MOTLoad may cause memory
|
|
corruption
|
|
|
|

|
|
5) When generating code (especially C++) for this system, one should
|
|
use at least gcc-3.2 (preferrably a copy downloaded from the RTEMS
|
|
site [snapshot area] )
|
|
|
|
6) To reboot the RTEMS-MVME5500 (board reset), one can invoke the
|
|
bsp_reset() command at Cexp> prompt.
|
|
|
|
7) Please reference http://www.slac.stanford.edu/~strauman/rtems
|
|
for the source code and installation guidance of cexp, GeSys and
|
|
other useful utilities such as telnet, nfs, and so on.
|
|
|
|
8) To get started with RTEMS/EPICS and to build development
|
|
tools and BSP, I would recommend one to reference
|
|
http://www.aps.anl.gov/epics/base/RTEMS/tutorial/
|
|
in additional to the RTEMS document.
