Specifications
Additionally, the developer should adjust the BOOT_CFG settings for specified QSPI Nor Flash device,
by exchanging the pull up/down resistors. See the main board schematic for more information.
2.8
NAND flash
NAND flash is not populated by default on the i.MX 6UltraLite EVK board. If the developer wants to boot
from the NAND flash, the following reworks should be implemented:
1. Remove the QSPI Nor flash device
2. Populate the NAND device
3. Change the Boot-mode switch (SW601) settings to ON, ON, OFF, ON
4. Additionally, the developer should adjust the BOOT_CFG settings for specified NAND Flash
device, by exchanging the pull up/down resistors. See the main board schematic for more
information.
Note that the data lines of NAND flash are multiplexed with the eMMC and MicroSD, so they can’t be
used at the same time.

Dual ethernet connector (J1501)
There are two Ethernet MAC controllers in the i.MX 6UltraLite processor. The Ethernet subsystem of the
i.MX 6UltraLite EVK board is provided by the MICREL KSZ8081RNB 10/100M Ethernet Transceiver
(U1501, U1601) and a dual port RJ45 (J1501) with integrated Magnetic.
The MAC addresses are shown on the sticks upon the RJ45 connector.

USB PHY connector (J1102, J1101)
The i.MX 6UltraLite Applications Processors contains two high speed (HS) USB 2.0 OTG (Up to 480
Mbps) controllers, with two integrated HS USB Phy. On the EVK board, J1101 is a Type-A connector for
USB host port, J1102 is a Micro-B connector for USB OTG port. The OTG port J1102 is also used for
downloading the boot image by MFGTool in Serial Download Mode.
