2.1 i.MX 6UltraLite processor
The i.MX 6UltraLite processor represents Freescale Semiconductor’s latest achievement in integrated
multimedia-focused products offering high performance processing with a high degree of functional
integration, targeted towards the growing market of connected devices. The i.MX 6UltraLite processor
features Freescale’s advanced implementation of the single ARM®Cortex®-A7 core, which operates at
speeds up to 528 MHz. The i.MX 6UltraLite includes integrated power management module that reduces
the complexity of external power supply and simplifies the power sequencing. Each processor provides a
16-bit DDR3/LVDDR3/LPDDR2 memory interface and a number of other interfaces for connecting
peripherals, such as WLAN, Bluetooth, GPS, displays, and camera sensors.
The more detail information about the processor can be found in the datasheet and the reference manual,
which can be obtained from the Freescale website.
2.2 Boot mode configurations
BOOT_MODE[1:0] are used to select system boot mode. On the i.MX 6UltraLite EVK board, a
dual-switch (SW602) is used to select the input voltage of these two pins, either 0 or 3.3 V.

Figure 4. SW602 boot mode settings
Typically, internal boot is selected for normal boot, which is configured by external BOOT_CFG GPIOs.
Then the developer must set the switch SW602: D2(MODE0) to OFF, D1(MODE1) to ON, and use
SW601 to select the boot device. This is shown in the following table and figure.

Figure 5. SW601 boot device settings
On the i.MX 6UltraLite EVK board, the default boot device is USDHC interface. There are two SD slots
on the board, one MicroSD (USDHC-2) on the Main board, one standard SD (USDHC-1) on the Base
board, MicroSD (USDHC-2) is the default boot device. If the developer wants to boot from the SD
(USDHC-1) by default, need to remove R613 (10K) and install R642 (10K). The location of the R613 and
R642 is on the bottom side as show in the following figure.

2.3 Power tree
A DC5V/3.5A external power supply with a 2.1 mm x 5.5 mm plug is used to supply the i.MX 6UltraLite
EVK board at connector J2001, and a slide switch SW2001 is used to turn the power ON/OFF. There is an

over-voltage protection circuit at the input power rail, so if the output voltage of the power supply exceeds
5.6V, the circuit will shut the system down. Discrete regulators are used to generate different power rails
for the whole system.
The power tree is shown in the following figure.
