10 NXP Semiconductors
2.6. Hyper Flash
On the MIMXRT1050 EVK Board, there is one 512Mbit Hyper Flash device. If the developer wants to
boot from the Hyper Flash, the boot device switch (SW7) settings should be: OFF. ON, ON, OFF, as
shown in Table3.
2.7. QSPI Flash
A 64Mbit QSPI Flash is used on the MIMXRT1050 EVK Board. If the developer wants to boot from the
QSPI Flash, the boot device switch(SW7) settings should be: OFF, OFF, ON, OFF, as shown in Table3.
By default, this QSPI Flash is disabled on the EVK. To enable it, Hyper Flash should be removed when
the QSPI Flash is selected as the boot device. And R153, R154, R155, R156, R157, R158 should add 0
Ohm resistors.
2.8. Ethernet Connector
There is one Ethernet Mac controller in the MIMXRT1050 processor. The Ethernet subsystem of the
MIMXRT1050 EVK Board is provided by the KSZ8081RNB 10/100M Ethernet Transceiver (U16) and
a RJ45 (J19) with integrated Magnetic.
The MAC address is shown on the stick upon the RJ45 connector.

2.9. USB PHY Connector
The MIMXRT1050 contains 2 integrated USB 2.0 PHYs capable of connecting to USB host/device
systems at the USB low-speed (LS) rate of 1.5 Mbits/s, full-speed (FS) rate of 12 Mbits/s or at the USB
2.0 high-speed (HS) rate of 480 Mbits/s.
2.10. Audio input / output Connector
The Audio CODEC used on the MIMXRT1050 EVK Board is Wolfson’s Low Power, high quality
Stereo Codec, WM8960.The MIMXRT1050 EVK Board include one headphone interface (J12), one
