generates an interrupt (intended to be a software-controllable(power-down). An approximate 5 seconds
or more pressing causes a forced OFF. Both boot mode inputs can be disconnected.
2.15.3. Reset Button
There are two Reset Button on the EVK Board. SW3 is the Power Reset Button. Pressing the SW3 in the
Power On state will force to reset the system power except SNVS domain. The Processor will be
immediately turn off and reinitiate a boot cycle from the Processor Power Off state. SW4 is Reset
Button.
2.15.4. USER Button
SW8 is the USER Button(GPIO5-00) for developers using. Pressing can produce changes in high and
low levels.
2.16. Sensor
U32 on the EVK Board is a 6-Axis Ecompass (3-Axis Mag, 3-Axis Accel) sensor FXOS8700CQ. The
Ecompass is connected to i.MX RT1050 I2C1 port.
2.17. User Interface LED Indicator
There are four LED status indicators located on the EVK Board. The functions of these LEDs include:
•
Main Power Supply(D3)
Green: DC 5V main supply is normal.
Red: J2 input voltage is over 5.6V.
Off: the board is not powered.
•
Reset RED LED(D15)
•
OpenSDA LED(D16)
•
USER LED(D18)
2.18. LCD Interface
The enhanced Liquid Crystal Display Interface (eLCDIF) is a general purpose display controller.
The eLCDIF block supports the following:
•
Displays that support moving pictures and require the RGB interface mode (DOTCLK interface).
The eLCDIF provides fully programmable functionality to supported interfaces:
•
Bus master interface to source frame buffer data for display refresh.
•
8/16/18/24/32 bit LCD data bus support available depending on I/O mux options.
•
Programmable timing and parameters for DOTCLK LCD interfaces.
