2.15.3 Reset button
There are two Reset buttons on the EVK board. SW3 is the power-on reset button. Pressing SW3 in the power on state forces
to reset the system power except SNVS domain. The processor immediately turns off and reinitiates a boot cycle from the
processor power off state. SW9 is a reset button.
2.15.4 USER button
SW8 is a USER button (GPIO5-00). Pressing the USER button 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 RT1060/1064 I2C1 port.
The sensor is not populated on some boards.
NOTE
2.17 User interface LED indicator
There are four LED status indicators on the EVK board.
The functions of these LEDs include:
• Main Power Supply (D3)
— Green: DC 5 V main supply is normal.
— Red: J2 input voltage is over 5.6 V.
— Off: Board is not powered.
• Reset RED LED (D21)
• OpenSDA LED (D20)
• 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.
To use the LCD, NXP provides an optional LCD module RK043FN02H-CT. RK043FN02H-CT has a 4.3 inches touch screen and
supports a resolution of up to 480*3(RGB)*272. This module contains two FPC cables. The LCD interface is connected to J8
(A1-A40) and the CPT interface can be connected to J8 (B1-B6). You can purchase LCD modules from
