Specificationsi.MX 8M Mini LPDDR4 EVK Board Hardware User's Guide, User's Guide, Rev. 0, 02/2019NXP Semiconductors 112.4. eMMC memory (U4)The eMMC memory is connected to the uSDHC3 interface of i.MX 8M Mini, and it can support up toeMMC 5.1 device. The eMMC memory is on the 8MMINILPD4-CPU board, and the part number isSDINBDG4-16G-I. It is the default boot device of the EVK. The boot settings are as shown in Table 3.2.5. QSPI Nor Flash (U5)The QSPI memory is connected to the FlexSPI interface of i.MX 8M Mini, and it can support up to166 Mhz DDR mode device. The QSPI memory is on the 8MMINILPD4-CPU board, and the partnumber is MT25QU256ABA1EW7-0SIT. To select it as the boot device of the EVK, developers canrefer to the boot settings as shown in Table 3.2.6. SD card slot (J701)There is one MicroSD card slot (J701) on the 8MMINI-BB board, connecting to the uSDHC2 interfaceof i.MX 8M Mini. This connector supports one 4-bit SD3.0 MicroSD card. To select it as the bootdevice of the EVK, developers can refer to the boot settings as shown in Table 3.2.7. MIPI-CSI&MIPI-DSI connectors (J802, J801)The i.MX 8M Mini processor supports one 4-lane MIPI-CSI and one 4-lane MIPI-DSI. The MiniSASconnectors are designed to support camera and LCD with dedicated pin definition. The connectors are asshown in Figure 2.2.8. Ethernet connector (J501)The Ethernet subsystem of the EVK board is provided by the Qualcomm AR8031 Ethernet Transceiver(U501). The Ethernet Transceiver (or PHY) receives standard RGMII Ethernet signals from the MAC-NET core of the i.MX 8M Mini. The processor handles all Ethernet protocols at the MAC layer andabove. The PHY is only responsible for the Link Layer formatting. The Ethernet connector (J501)integrates Magnetic transformer inside, so it cannot be directly connected to AR8031 (U501).Each EVK board has a unique MAC address, which is burned into i.MX 8M Mini by Fuse, and the labelis stuck on the connector very clearly.2.9. USB connector (J301, J302)The i.MX 8M Mini Applications Processors contain two USB 2.0 OTG controllers, with two integratedUSB PHY. There are two USB Type-C connectors on the EVK board, both can support Host and DeviceMode.J301 is connected to USB1 interface of i.MX 8M Mini, which can act as the download port of the EVK.J302 is connected to USB2 interface of i.MX 8M Mini, which can act the power supply port of the EVK.
