3 | The bootloader is adapted from Till Straumann's Generic Mini-loader, |
---|
4 | which he wrote originally for the SVGM powerpc board. Part of the |
---|
5 | BSP was derived from the "RTEMS-PowerPC BSPs" and the NetBSD projects. |
---|
6 | As of today, the BSP is built and tested on the RTEMS-4.6.0 |
---|
7 | release with small patches I added (see README.rtems-4.6.0-patch |
---|
8 | and rtems-4.6.0-patch/ directory). |

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

---|
32 | Update Global Environment Area of NVRAM (Y/N) ? Y |
---|
33 | MVME5500> |
---|
34 | |
---|
35 | Note : (cxx.xx.xx.xx is the client IP address and |
---|
36 | sxx.xx.xx.xx is the server IP address) |

---|
40 | |
---|
41 | 5) When generating code (especially C++) for this system, one should |
---|
42 | use at least gcc-3.2 (preferrably a copy downloaded from the RTEMS |
---|
43 | site [snapshot area] ) |
---|
44 | |
---|
45 | 6) To reboot the RTEMS-MVME5500 (board reset), one can invoke the |
---|
46 | rtemsReboot() command at Cexp> prompt. |
---|
47 | |
---|
48 | 7) Please reference http://www.slac.stanford.edu/~strauman/rtems |
---|
49 | for the source code and installation guidance of cexp, GeSys and |
---|
50 | other useful utilities such as telnet, nfs, and so on. |
---|
51 | |
---|
52 | 8) To get started with RTEMS/EPICS and to build development |
---|
53 | tools and BSP, I would recommend one to reference |
---|
54 | http://www.aps.anl.gov/epics/base/RTEMS/tutorial/ |
---|
55 | in additional to the RTEMS document. |

---|
58 | TODO lists: |
---|
59 | 1) 1 GHZ ethernet ( work in progress, to be released soon) |
---|
60 | 2) To measure the interrupt latency and context switching. |
---|
61 | 3) To implement the watchdog timer. |
