2.7 SD card slot (J11)
There is one MicroSD card slot (J11) on the 8MPLUS-BB board, connect to the uSDHC2 interface of i.MX 8M Plus. This connector
supports one 4-bit SD3.0 MicroSD card. To select it as the boot device of the EVK, developers can refer to the boot settings as
shown in
.
2.8 MIPI-CSI connectors (J12, J13)
The i.MX 8M Plus processor supports two 4-lane MIPI-CSI. These signals are connected to two separate MiniSAS connectors,
which can be connected to MINISASTOCSI accessory card. The connectors are as shown in
2.9 MIPI-DSI connector (J14)
The i.MX 8M Plus processor supports one 4-lane MIPI-DSI, the resolution can be up to 2560 × 1080p60. These signals
are connected to MiniSAS connector, which can be connected to IMX-MIPI-HDMI or MX8-DSI-OLED1A accessory card. The
connectors are as shown in
2.10 LVDS connectors (J15, J16)
The i.MX 8M Plus processor supports two 4-lane LVDS TX display, the resolution can be up to 1366x768p60 for each channel,
and 1920x1080p60 for dual asynchronous channels. These signals are connected to two separate MiniSAS connectors, which
can be connected to IMX-LVDS-HDMI accessory card. The connectors are as shown in
2.11 HDMI connector (J17)
The i.MX 8M Plus processor supports the HDMI 2.0a display output specification along with eARC audio input. The 8M Plus
supports ARC over
SPDIF_RX
which is muxed behind the
I2C5_SDA
pin on the EVK. The i.MX 8M LPDDR4 Plus EVK board has
a Type-A HDMI connector, the resolution can be up to 4Kp30. The connector is as shown in
.
2.12 Ethernet connectors (J8, J9)
The Ethernet subsystem of the EVK board is provided by the Realtek RTL8211FDI-CG Ethernet Transceiver (U23, U26) and
Ethernet RJ45 connectors (J8, J9). The Ethernet Transceivers (or PHYs) receive standard RGMII Ethernet signals from the
MAC-NET core of the i.MX 8M Plus. The RJ45 connectors integrate Magnetic transformer inside, so they can be directly
connected to Ethernet Transceivers (or PHYs).
Each Ethernet port has a unique MAC address, which is burned into i.MX 8M Plus by Fuse, and the labels are stuck on the
connectors very clearly.
The connectors are as shown in
2.13 USB connectors (J5, J6, J7)
The i.MX 8M Plus Processor contains two USB 2.0/3.0 controllers, with two integrated USB PHY. On the EVK board, one is
used for the USB Type-C Port1 (J6) and the other for USB3.0 Host Port2 (J7).
USB Type-C Port0 (J5) is used for power only. It does not support USB data transfer. It's the only power supply port therefore it
must always be supplied for system power.
The connectors are as shown in
2.14 CAN Bus connectors (J19, J20)
The i.MX 8M Plus Processor contains two CAN FD controllers. On the EVK board, the two controllers are connected to the dual
high-speed CAN transceiver TJA1048T, then connected to two DB9 female connectors. The connectors are as shown in
.
