* RFS mounted via NFS
* processor's LDO is enabled (required to perform voltage scaling)
* Power monitors: two custom current probes have been used
**power probe #1 is connected to the input power rail at 12V; the 12V power rail is used to power the entire system including LCD panel logic and backlight
**power probe #2 is connected to the input power rail of the PMIC NXP PF3000; this, in turn, powers NXP iMX6UL processor, DDR3L SDRAM, Flash memories, Ethernet PHY
The following table shows the summary result of data collected at different checkpoints:

Additional notes and reference:
* U-boot is set to work at 396MHz
* At U-boot prompt the LCD interface and circuitry are in off state
* At Linux prompt, a fixed clock frequency of 528MHz has been set (userspace governor)
* All the measures include Ethernet link at 100M, and power requirement for two USB memory sticks and an uSD card
* StressAppTest application is used to stress CPU and DDR3 RAM (https://github.com/stressapptest/stressapptest)
* A 4.3 inches 480x272 LCD is used to test the 24bit parallel video interface output. The LCD backlight is driven by the 12V VIN using an external circuitry at 100% brightness
