| CDF Flash RAM Build/Install Instructions |
This page contains instructions for rebuilding and installing new versions of the MVME 2301 VxWorks flash ram image. It is recommended that these procedures be done only by those who completely understand then. If an error is made, the board will have to be pulled from the crate and a complex recovery procedure performed in order to be made bootable again. This might be painful for a processor on the detector. So, Be Careful!
If the board is an MVME2304, as used in the SVX and SVT subsystems, then substitute mv2305-cdf for mv2301-cdf below.
DANGER: Loading the incorrect flavor kernel into an MVME will render it unuseable! You will then have to switch back to PPCbug or MOTload booter by changing the board boot jumpers and/or have to load the VxWorks kernel over the network temporarily. In some cases both boot RAMs can be erased, requiring a slow and expensive factory repair!
| Instructions | 2300 * | 2400 | 5500 ** |
|---|---|---|---|
| In the boot parameters, change the kernel file to:
and reboot the board |
kernel/mv2301/v5_3c/vxWorks | kernel/mv2400/v5_4a/vxWorks | kernel/mv5500/v5_5la/nogigE/vxWorks |
| Log onto the board | |||
| Set directory to kernel area | cd "/cdf/onln/code/cdfprod" cd "vxworks_kernel/mv2301/v5_3c" |
cd "/cdf/onln/code/cdfprod" cd "vxworks_kernel/mv2400/v5_4a" |
cd "/cdf/onln/code/cdfprod" cd "vxworks_kernel/mv5500/v5_5la/nogigE" |
| Load Flash RAM This takes about 15 seconds. Do not interrupt this process! |
sysFlashProgramBootRom "vxWorks.st_rom" | sysFlashProgramBootRom "vxWorks_romCompress.bin" | mv5500FlashProgramModule "vxWorks_romCompress" |
| In the boot parameters, change the startup script to: | boot/front-end/startup.cdf | boot/front-end/startup.cdf | boot/front-end/startup.5500.cdf |
| Reboot the board | reboot | reboot | reboot |
** NB: The nogigE directory specification indicates that the kernel files in that area do not support the 5500 gigabit ethernet spigot. Replace with gigE to access the kernel files that do contain gigabit ethernet support. Currently only Trigger Supervisor node b0tsi00 uses the gigabit ethernet interface.
| Instructions | 2300 | 2400 |
| Log into node b0vxworks as user cdfprod Kernels must be built on a Sun machine | ||
| Setup vxworks | setup -q ppc vxworks v5_3c | setup -q mv2400 vxworks v5_5la |
| Set directory to kernel area | cd ${WIND_BASE}/target/config/mv2301-cdf | cd ${TOR_MV2400_DIR}/mv2400_vx/default |
| Set up CDF libraries | source setup_cdf.csh | source ../setup_cdf.csh |
| Build kernel | ./makeall.csh | make -f ../Makefile clean make -f ../Makefile vxWorks_romCompress.bin |
For mvme2305's substitute mvme2305 for mvme2301 above.
