  1. Boot Software Issues • Open NCRs: • Problems with CDMU Buslists (due to a too short timeout period between a TM request and the following TM Confirmation) NCR-HIF-CGS-C-013 • 1 ICU crash detected during FM Full Functional test, after the execution of the HIFI Warm reset. (Warm Reset could be very useful at low temperatures (see dedicated slide), due to a problem in the used FPGA chip). • A series of tests have been carried out at IFSI with SPIRE OBS + AVM2, and at CGS on HIFI OBS +FM. The tests implied the execution of a reboot and a jump to boot more than 100 times/hour. Both tests were carried out for 20 hours. NO crashes have been detected. • According to IFSI the NCR can be closed. • Documentation: • The full set of documents for BSW are now available on CGS ftp site. • Open SPRs: • No open SPR.

  2. FPGA chip problem • The problem is related to a high Inrush Current in the FPGA chip mounted • onboard ICU (and also onboard LCU, FCU, HRH/V and WEH/V) and is described in • the Alert Note from Actel attached to this email. • Due to the problem the ACTEL suggested wait time between a power off and the • following power on is reported in table 2 page 3 of the ACTEL note attached • to the email. • Temp(°C) Time (min) • -30 371 • 0 45 • 25 4.3 • 40 1.2 • 65 0.183
