Additional release documentation, files, and other materials for Release 6.2 are available on the B0-6-2 Release Page.

I. Functionality of Release 6.2

Release 6.2 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 6.2 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 6.2 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. FSW Packages Changed or Added in Release 6.2

Release 6.2 provides “flight” code modules, which are loaded and executed on LAT CPUs, and the corresponding source code. In addition, Release 6.2 contains unit tests, test support code, ground support utilities, and qualification test documents and scripts.

• FSW packages that were changed or added since Release 6.1 are itemized here.
• All FSW packages in Release 6.2 are itemized here.

III. JIRA Items in Release 6.2

Bug

• [FSW-413] - The definitions of SIU primary and SIU redundant are going to cause confusion.
• [FSW-428] - LSEP fails to clear unused bits; this is really just a failure to fix all the problems associated with FSW-417

• [FSW-466] - LATC parser has an endianness issue.
• [FSW-467] - ZLIB/ZFS unit test scripts out of date
• [FSW-468] - EDS_fwHandlerAssociate incorrectly handles the return value from the service callback routine.
• [FSW-472] - Extended Counters in the event datagrams do not increment properly at all times.
• [FSW-475] - LIM alert telemetry is sent to incorrect ITC queue.
• [FSW-476] - The global context structure is misaligned on little endian machines.
• [FSW-477] - Enumerations specifying the number of bits in each symbol type encoded by LSEC and decoded by QSEC are repeated in these two packages.
• [FSW-478] - Insufficient memory allocated for the compression and decompression of calibration data.
• [FSW-479] - Calibration decoders do not work on little endian machines
• [FSW-480] - LATC verify fails on some tracker front ends on the dalek.
• [FSW-482] - ARC and AFE read timeout values are incorrect.
• [FSW-485] - When LCI_parser is used to create a configuration file with the same name as an existing file it does not erase previous contents
• [FSW-486] - LATC_parser gives incorrect output for components with an odd number of 16 bit registers when executed on little-endian machines
• [FSW-487] - Undocumented RO bits in the CRC CONFIG register need to be handled in LATC_capture
• [FSW-488] - In QSEP_evt0.c, the routine that decodes format 0, compress level 0 type events has a sign error in the handling of multipacket events
• [FSW-491] - LPA_DB Needs to Set LSEPW Datagram Encoding Level to 1
• [FSW-492] - A redunant (and over zealous) check within the calibration event compaction code causes an error.
