2.8. Ethernet connector
There is one Ethernet Mac controller in the MIMXRT1064 processor. The Ethernet subsystem of the
MIMXRT1064 EVK Board is provided by the KSZ8081RNB 10/100M Ethernet Transceiver (U16) and
a RJ45 (J19) with integrated Magnetic.
2.9. USB PHY connector
The MIMXRT1064 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 MIMXRT1064 EVK Board is Wolfson’s Low Power, high quality
Stereo Codec, WM8960.The MIMXRT1064 EVK Board include one headphone interface (J12), one
onboard MIC (P1), two speaker interfaces (J16, J17), and the SPDIF interface (J14 & J18, DNP). J12 is
a 3.5mm audio stereo headphone jack, which supports jack detect.
2.11. OpenSDA circuit (DAP-link)
The OpenSDA circuit (CMSIS–DAP) is an open-standard serial and debug adapter. It bridges serial and
debug communications between a USB host and an embedded target processor.
CMSIS-DAP features a mass storage device (MSD) bootloader, which provides a quick and easy
mechanism for loading different CMSIS-DAP Applications such as flash programmers, run-control
debug interfaces, serial-to-USB converters, and more. Two or more CMSIS-DAP applications can run
simultaneously. For example, run-control debug application and serial-to-USB converter runs in parallel
to provide a virtual COM communication interface while allowing code debugging via CMSIS-DAP
with just single USB connection.
For the MIMXRT1064 EVK Board, J41 is the connector between the USB host and the target processor.
Jumper to serial downloader mode to use stable DAP-Link debugger function. If developer wants to
make OpenSDA going to the bootloader mode, J43 should jumper to 1-2, and press SW4 when power
on. Meanwhile, the OpenSDA supports drag/drop feature for U-Disk. First, use the seral downloader
mode and drag/drop the image file to U-Disk. Then select QSPI Flash as boot device and reset the
Board, the image will run.
2.12. JTAG connector
J21 is a standard 20-pin/2.54 mm Box Header Connector for JTAG. The pin definitions are shown in the
following figure. Support SWD by default.
