EV-iMX287-SODIMM SOM Structure

The second chip of PHY Etnernet can be attached on an external baseboard, connected via  RMII interface. Distinctive feature of this SOM is possibility of installation a e-MMC chip memory with a maximum capacity up to 16 Gbytes. It allows to use ready file systems, such as Debian directly in memory of the module. For applications not demanding large volume of memory the SLC NAND Flash installation with a capacity up to 512 Mb is provided. All signals and processor interfaces, such as UART, I2C, CAN, GPMI, RMII, SSP, LCD, ADC connected to 200-pin SODIMM connector. Working temperature range of the module  -40... + 85C.

For Quick Start  Evodbg provide a EV-iMX287-SODIMM-MB baseboard with SODIMM socket and other connectors and components installed:

  • 5V Power Connector (5.5/2.1 mm)
  • 2 USB-A Connectors
  • 2 Ethernet RJ-45 connectors
  • 2 CAN connectors
  • 2 RS-485 connectors
  • One DUART (RS-232) for console and debug
  • Standart 20-pin JTAG connector
  • 2 UEXT connectors
  • DIP switch for source boot select
  • PLD40 for TFT displays connect
  • SODIMM 1V8 for EV-iMX287-SODIMM module
  • Dimension 100*100 mm
  • 4 layers
For building of u-boot, a Linux kernel and rootfs  the adjusted virtual computer with the Ubuntu operating system is provided.The following components are installed in the virtual machine:
