FSW B0-6-4 Release Notes

This page summarizes the functionality included in FSW Release 6.4 (B0-6-4) and lists the JIRA issues resolved in the Release.

User procedures for Release 6.3 are described in the LAT Flight Software User Guide. These procedures are largely unaffected by the JIRA issues corrected in Release 6.4. Exceptions are discussed below. Also review the entries for the JIRA items resolved in Release 6.4.

Additional files, materials, and release documentation for Release 6.4 (including complete 6.4 command and telemetry interface reference documentation) are available on the B0-6-4 Release Page.

I. Functionality of Release 6.4

Release 6.4 supports end-to-end operation of the LAT using the SIU and EPUs and provides all functionality required for “software checkout” and Phase I (full LAT) testing in Building 33. Release 6.4 has the following capabilities:

  • Full support for LAT internal hardware interfaces and the LAT external interfaces with the Spacecraft.
  • Full boot capabilities on the SIU and EPUs
  • CPU watchdog management
  • Command and telemetry processing and a complete set of commands and telemetry to support end-to-end operations, as well as handle Spacecraft ancillary messages
  • Processing of all time signals and messages from the Spacecraft, and drift-corrected timekeeping
  • CPU memory and EEPROM file system management
  • Delivery of event data from the hardware to the Spacecraft Solid State Recorder
  • Configurable filtering of event data
  • Collection of charge injection calibration data
  • Operational mode control to manage pointed observations, sky survey observations, and target of opportunity observations
  • Load shed management and operations during SAA transit
  • Thermal control system
  • Instrument configuration by file and readback of instrument configuration

Release 6.4 does not support collection of instrument diagnostic data (CR calibration data, trigger rate data, etc). It also does not fully implement automatic repoint requests and LAT GRB detection algorithms, nor does it support the external interface to the GBM or GBM message exchange.

II. Procedure Changes Since Release 6.3

  • To address JIRA item FSW-539, the offline LCI_parser utility was modified to recognize a new calibration run control configuration parameter, <latc_delay>, to supplement the existing <delay> parameter. This new "LATC settling period" is imposed at the start of each calibration cycle. Both <latc_delay> and <delay> are specified in increments of 1/100 second; 200 is a typical value for <latc_delay>, while 2 is typical for <delay>. The <latc_delay> parameter is valid in LCI configuration files for any type of calibration: ACD, TKR, or CAL.
  • New fields were added to the CpuMetr housekeeping telemetry packet (APID 0x22B): LHKSIUPCIERR, LHKSIUCMERR, LHKSIUUMERR, LHKEPU0PCIERR, LHKEPU0CMERR, LHKEPU0UMERR, LHKEPU1PCIERR, LHKEPU1CMERR, LHKEPU1UMERR, LHKEPU2PCIERR, LHKEPU2CMERR, LHKEPU2UMERR. These fields store counters for the number of RAD750 bridge chip hardware errors (PCI, correctable memory, and uncorrectable memory, respectively) encountered on the SIU and each EPU. See the command and telemetry interface reference documentation posted on the B0-6-4 Release Page for the layout of the new CpuMetr packet.

III. FSW Packages Changed or Added in Release 6.4

Release 6.4 provides “flight” code modules, which are loaded and executed on LAT CPUs, and the corresponding source code. In addition, Release 6.4 contains unit tests, test support code, ground support utilities, and qualification test documents and scripts.

  • FSW packages that were changed or added since Release 6.3 are itemized here.
  • All FSW packages in Release 6.4 are itemized here.

IV. JIRA Items Resolved in Release 6.4

Unresolved
