How to avoid a BSOD on your 2B dollar spacecraft

A critical spacecraft test encountered errors due to incorrect memory addresses being uploaded. Engineers discovered the Enhanced Remote Interface Unit (ERIU) had crashed, preventing system shutdowns and blocking telemetry updates. To resolve the issue, they had to carefully reboot the onboard computer without triggering safemode, a risky procedure involving disabling watchdog timers and executing precise command sequences. After 12 hours of troubleshooting, the team successfully powered down the spacecraft safely at 1:45 AM. This incident highlights the complexities and challenges of spacecraft testing and the importance of accurate configuration data.
