ICU Code Load

Version 17 - Last modified 22 Dec 2011

Location

Written procedure on Docushare: https://www.swift.psu.edu/docushare/dsweb/View/Collection-127
Further detail: http://www.mssl.ucl.ac.uk/swift/docs/procedures/

Purpose

Load release16_1 code to the ICU.

Steps to run

Deliveries

Updated written procedures - especially slew warnings? Not this time.
*.img load images - rename these first to include the release name
Don't need to update dump lengths in Spacecraft RTSs 61-3
icrc_tables_r.proc
VDD

Loads

All commanding is via Malindi or USN except where specified to the right of the command.
First check the checksums in a terminal window (shell) not ITOS! This should be done before CVS version control as a cvs commit will slightly change some of the files and change the md5sums.

cd loads
md5sum -c MD5SUMS

You should see OK for each file which is there.

start icu_safe --TDRSS fwd link to save down time

start iloads_0_r -- contains Moon (and, if necessary, Sun) constraint reduction

load rts_v16_1#2.img -- 2 min

load rts_v16_1#3.img -- 2 min

load rts_v16_1#4.img -- 0 min

load rts_ndx_v16_1.img -- 0 min

start icu_reload

start icu_tdrsshk_on(480)

start icu_idle

start ortsstart(61)

Wait until next MAL pass

start icueeprom(0x391)

Check the EEPROM dump with the Ground Reference Images

start icrc_tables_r(0x391) -- return at end of pass Changes after load

uvot_limits.proc -- change limits of SBCTXERRCNTICU
icueeprom.proc -- change CRCs
