Reboot tests for nodes in order to

* Test RTC persistence (Does RTC battery still work)
10
* Test bootup issues (delay for flash chips) (CANDIS SPI Flash issues)
11
* Test battery livetime (How long does miniminutnik run on one charged battery)

h2. Parts

15
* PI5C3257QE; 4xSPDT; 1 Schalter; 0.229€; 2 of them.
16
* N+P-MOSFET for power switching
17
* Button for device switching
18
* Orange-LED: Target is on; Violet LED: Target is off (Awira is connected); Orange-Blinking: Test running; Violett-Blinking: Test running; Alternating: Target powered only
19
* Red-Blinking: Test failed; Red-On: Test succeeded
20
* 3V output e.g. for Miniminutnik reboot tests
21
* 5V Input when CAN (-connector) is not available
22
* Transceiver, STM32F072, voltage regulator

h2. Behaviour
25
26
Awaria has Debug+CANBus 'input' which can be disconnected by electrical switches
27
To the own debug output either target device or awarias UART is routed.
28
A running test is interrupted

* Measure current? I don't have a 'nice' device which does such thing yet. Here an additional UART would make sense to access Awaria while target is running. But power and routing is seperated.
