3 | The bootloader is adapted from Till Straumann's Generic Mini-loader, |
---|
4 | which he wrote originally for the SVGM powerpc board. |
---|
5 | The BSP is built and tested on the 4.7 CVS RTEMS release. |
---|

7 | Booting requirement : |
---|
8 | ------------------------- |
---|
9 | |
---|
10 | 1) One needs to setup BOOTP/DHCP and TFTP servers and /etc/bootptab(BOOTP) |
---|
11 | or /etc/dhcpd.conf (DHCP) properly to boot the system. |
---|
12 | (Note : EPICS needs a NTP server). |
---|
13 | |
---|
14 | 2) Please copy the prebuilt RTEMS binary (e.g. misc/rtems5500-cexp.bin) |
---|
15 | and perhaps others (e.g. misc/st.sys) to the /tftpboot/epics/hostname/bin/ |
---|
16 | directory or the TFTPBOOT one you specified in the 'tftpGet' |
---|
17 | command of the boot script (as shown in the following example). |
---|
18 | |
---|
19 | 3) Example of the boot script setup carried out on the MOTLoad |
---|
20 | command line : |
---|
21 | |
---|
22 | MVME5500> gevEdit mot-script-boot |
---|
23 | (Blank line terminates input.) |
---|
24 | tftpGet -a4000000 -cxx.xx.xx.xx -sxx.xx.xx.xx -m255.255.254.0 -d/dev/enet0 -fepics/hostname/bin/rtems5500-cexp.bin |
---|
25 | netShut |
---|
26 | go -a4000000 |

---|
31 | |
---|
32 | Note : (cxx.xx.xx.xx is the client IP address and |
---|
33 | sxx.xx.xx.xx is the server IP address) |
---|

35 | 4) Other reference web sites for mvme5500 BSP: |

---|
40 | 5) When generating code (especially C++) for this system, one should |
---|
41 | use at least gcc-3.2 (preferrably a copy downloaded from the RTEMS |
---|
42 | site [snapshot area] ) |
---|
43 | |
---|
44 | 6) To reboot the RTEMS-MVME5500 (board reset), one can invoke the |
---|
45 | rtemsReboot() command at Cexp> prompt. |
---|
46 | |
---|
47 | 7) Please reference http://www.slac.stanford.edu/~strauman/rtems |
---|
48 | for the source code and installation guidance of cexp, GeSys and |
---|
49 | other useful utilities such as telnet, nfs, and so on. |
---|

---|
51 | 8) To get started with RTEMS/EPICS and to build development |
---|
52 | tools and BSP, I would recommend one to reference |
---|
53 | http://www.aps.anl.gov/epics/base/RTEMS/tutorial/ |
---|
54 | in additional to the RTEMS document. |
