| 3 | There are some issues that can only be tested via power resets. |

| 5 | * SPI has an issue that it needs retries |
||
| 6 | * Looks like configuration I2C EEPROM gets reset to defaults |

| 9 | 3 | Maximilian Seesslen | The device has an CANBus in and an CANBus out. The testsoftware is on the DUT. The DUT sends the command to toggle power line to Awaria via CAN. |
| 10 | The switch-off time has to be an parameter. The RTC-Tests will be complex, the Awaria software shall be simple and generic. |

| 12 | An data multiplexer can be used along with a mosfet for power line. |
