(a) The software failure incident related to the Raspberry Pi 2 board blinking when hit with a high-intensity camera flash is specific to the Raspberry Pi Foundation's product. There is no mention in the article of a similar incident happening before within the same organization.
(b) The article does not mention any similar incident happening at other organizations or with their products and services. |
| Phase (Design/Operation) |
design |
(a) The software failure incident related to the design phase is evident in the Raspberry Pi 2 board. The article mentions that the device has a slight defect that causes it to blink every time it's hit with a high-intensity camera flash. This issue is attributed to the device's U16 processor core power regulator being affected by high-intensity light, causing the device to power down. The Raspberry Pi Foundation spokeswoman, Liz Upton, explains that the problem is related to a photoelectric effect on the U16 processor core power regulator, where the semiconductor material emits electrons, leading to the device shutting down [34023].
(b) The software failure incident related to the operation phase is highlighted in the same article. It is mentioned that the issue with the Raspberry Pi 2 board occurs under very specific conditions, specifically when it is hit with flashes of high-intensity, long-wave light like xenon flashes or laser pointers. However, the problem does not occur with older non-Xenon flashes or direct sunlight. The Raspberry Pi Foundation has found a quick fix for the issue, recommending covering the chip with moldable glue or putty-like material to prevent the device from powering down even when exposed to high-intensity flashes [34023]. |
| Boundary (Internal/External) |
within_system |
The software failure incident related to the Raspberry Pi 2 board blinking when hit with a high-intensity camera flash can be categorized as follows:
(a) within_system: The failure is caused by a defect within the Raspberry Pi 2 board itself. The issue is related to the U16 processor core power regulator on the board being affected by high-intensity light, causing the device to power down. This defect originates from within the system and is not caused by external factors [34023].
(b) outside_system: The failure is not due to contributing factors that originate from outside the system. The incident is specifically triggered by high-intensity, long-wave light such as xenon flashes or laser pointers, which are part of the environment in which the device operates. Other bright lights, including camera flashes using different technologies, do not cause the issue, indicating that the failure is not due to factors external to the system [34023]. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident related to the Raspberry Pi 2 blinking when hit with a high-intensity camera flash is attributed to a non-human action. Specifically, the issue is caused by a defect in the device's U16 processor core power regulator, which reacts to high-intensity bursts of light by dropping the core voltage, leading to the device turning off. This defect is a result of the photoelectric effect on the silicon die of the chip when exposed to certain types of light, causing the semiconductor material to emit electrons and disrupt the power supply circuitry, ultimately triggering the reboot of the device [34023]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident described in the article is related to hardware. The issue with the Raspberry Pi 2 board causing it to blink every time it's hit with a high-intensity camera flash is attributed to a defect in the hardware component responsible for regulating the processor core power (chip marked U16). The malfunction occurs due to the photoelectric effect on the device's U16 processor core power regulator when it is hit by high-intensity light, causing the semiconductor material to emit electrons and the device to power down [34023]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The articles do not mention any malicious intent or actions related to the software failure incident with the Raspberry Pi 2 board. The issue with the device blinking when hit with a high-intensity camera flash is described as a defect caused by the photoelectric effect on the U16 processor core power regulator [34023].
(b) The software failure incident with the Raspberry Pi 2 board is categorized as non-malicious. The problem was identified as a slight defect in the device that causes it to blink when exposed to high-intensity light, specifically xenon flashes or laser pointers. The Raspberry Pi Foundation addressed the issue by providing a quick fix involving covering the chip to prevent the power supply from dropping out [34023]. |
| Intent (Poor/Accidental Decisions) |
unknown |
The software failure incident related to the Raspberry Pi 2 board blinking when hit with a high-intensity camera flash does not directly involve software issues. Instead, it is a hardware-related problem caused by the photoelectric effect on the device's U16 processor core power regulator when exposed to high-intensity light [34023]. Therefore, the incident does not align with either poor_decisions or accidental_decisions related to software failures. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident related to the Raspberry Pi 2 board blinking when hit with a high-intensity camera flash was not due to development incompetence. The issue was explained by Raspberry Pi Foundation spokeswoman Liz Upton as a result of a photoelectric effect on the device's U16 processor core power regulator caused by high-intensity bursts of light [34023].
(b) The software failure incident with the Raspberry Pi 2 board blinking when exposed to a high-intensity camera flash was accidental. The issue was not intentional but rather a side effect of the device's design and the interaction with specific types of light sources, such as xenon flashes and laser pointers [34023]. |
| Duration |
temporary |
The software failure incident related to the Raspberry Pi 2 board blinking when hit with a high-intensity camera flash is temporary. The issue occurs only under very specific conditions, specifically when the device is hit with high-intensity, long-wave light such as xenon flashes or laser pointers. Older non-Xenon flashes and direct sunlight do not cause the problem, indicating that the failure is temporary and dependent on certain circumstances [34023]. |
| Behaviour |
crash, value, other |
(a) crash: The Raspberry Pi 2 board experienced a crash when hit with a high-intensity camera flash, causing it to turn off [34023].
(b) omission: The software failure incident did not involve the system omitting to perform its intended functions at an instance [34023].
(c) timing: The software failure incident did not involve the system performing its intended functions too late or too early [34023].
(d) value: The software failure incident involved the system performing its intended functions incorrectly due to the power supply chip malfunctioning when hit by high-energy bursts of light [34023].
(e) byzantine: The software failure incident did not involve the system behaving erroneously with inconsistent responses and interactions [34023].
(f) other: The other behavior observed in this software failure incident was the system's power supply chip malfunctioning when hit by high-energy bursts of light, causing the device to power down [34023]. |
