==== POWER GOOD signals selector - J10 ====
J10 is a 8-pin 4x2x2.54 pitch vertical header used for the selection - through jumpers - of the POWER GOOD options. The following table reports the pinout of the connector:

The available configurations are:
* No jumpers mounted (DEFAULT)
* Jumper on 1-2 -> supply BOARD_PGOOD with 3.3V_SOM
* Jumper on 3-4 -> supply 1.5V_POWER_GOOD with 3.3V_SOM
* Jumper on 5-6 -> supply 1.5V_VREF_POWER_GOOD with 3.3V_SBY
* Jumper on 7-8 -> supply 1.8V_VREF_POWER_GOOD with 3.3V_SBY
 
==== BANK35, BANK13 VDDIO selector - J11 ====
J11 is a 8-pin 4x2x2.54 pitch vertical header used for the selection - through jumpers - of the bank supply voltages. The following table reports the pinout of the connector:

The available configurations are:
# Jumper on 1-2 -> supply VDDIO_BANK35 with 3.3V ('''requirerd when EVBB DDR3 device is used''')
# Jumper on 3-4 -> ('''Not Available''') supply VDDIO_BANK35 with EVB_VDDQ_1V5 ('''requirerd when EVBB DDR3 device is used''')
# Jumper on 5-6 -> supply VDDIO_BANK13 with 3.3V
# Jumper on 7-8 -> supply VDDIO_BANK35 with EVB_VDDIO_BANK13 ('''requirerd when TRACE is used''')
 
The following rules must be observed:
* Because of a hardware limitation, VDDIO_BANK35 '''must be configured for 3.3V power supply (Jumper on 1-2)'''.
* The configuration 1. (Jumper on 1-2) excludes 2. (Jumper on 3-4) (and viceversa)
* The configuration 3. (Jumper on 5-6) excludes 4. (Jumper on 7-8) (and viceversa)
 
The DEFAULT configuration is:
* Jumper on 1-2 ('''please note that this jumper must not be removed''')
* Jumper on 5-6
