Measurements have been performed on the ETRA SOM under test is equipped with:
* STM32MP157 Dual Core A7 3D GPU (p.n. STM32MP157DAB1STM32MP157AAB3)
* 512 MB DDR3L
* 8 GB eMMC
100 Mbps Ethernet link has been always active disconnected during the test.
The table below reports the power consumption measurements for the considered use cases.

(*) Stressful Application Testwakeup from GPIO  (**) wakeup from RTC or GPIO  ===== Wakeup =====For RTC wakeup it is possible to use this simple commands:  <code>wakeuptime=`date -d "1 minute" +%s`</code>
<code>rtcwake -lt$wakeuptime</code>
