Idle configurations
* SBC Lynx rev.0 (S-XUBB0000C0R)
* System software: [[SBC_Lynx_Embedded_Linux_Kit_(XUELK)|XUELK 0.9.0]]
* RFS UBIFS root file system mounted via UBIFS in from Flash NAND
* processor's LDO is enabled (required to perform voltage scaling)
* Some HW modifications are required to obtain the minimum power consumption:
* Power monitors: two custom current probes have been used
**power probe #1 is connected to the input power rail at 12V
**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 PHYprocessors subsystem, as depicted in TBD
Two idle configurations have been tested, detailed in the following sections. Nomenclature is the same used in the processor's data sheet<ref name="IMX6ULIEC">Freescale Semiconductor, ''i.MX 6UltraLite Applications Processors for Industrial Products Data Sheet'', Rev. 1, 04/2016</ref>.
*CAN PHY
*RS485 polarization network
*RS232 and RS485 are in shutdown modetransceivers*Ethernet linkPHY
[2] 24MHz active oscillator power consumption is included. As the board under test is equipped with iMX6UL revision 1.0, active oscillator is required to implement the fix described by errata ERR009455. Typical consumption of this oscillator is about 20mW. Future revision of the board will be populated with silicon revision 1.1 or newer. Thus active oscillator will be removed. For more details please refer to ''Chip Errata for the i.MX 6UltraLite''<ref name="IMX6ULCE">Freescale Semiconductor, ''Chip Errata for the i.MX 6UltraLite'', Rev. 0.1, 02/2016</ref>.
