4.2.1. J7200 EVM Hardware Setup

Description

The J7200 Evaluation Module provides an affordable platform to quickly start evaluation of Jacinto™ DRA8xx Processors and accelerate development for Infotainment, ADAS, Gateway and many other automotive applications.

The J7200 Evaluation Module consists of a SoM(System on Module) and a common processor board.

J7VCL SOM

The J7200 Evaluation Module consists of a SOM (System on Module), shown in the red box below, fitted to a common processor board or base EVM.

Contents of the board

  • J7200 SoC
  • Power controller
  • 4 GiB DDR RAM
  • OSPI NOR flash
  • Hyperflash

Common Processor Board

The Common Processor Board is the main board which has peripherals to provide most common functionality. It provides connections to different adapter cards.

This board is used across multiple Jacinto 7 variants. Therefore, not all the functionality provided by the Common Processor Board will necessarily be available for use with J7VCL.

Contents of the board

Refer to EVM connections for detail information regarding connecting peripherals to Common Processor Board

  • 12V Power input
  • 4xUART to USB port for Main uarts
  • 2xUART to USB port MCU domain uarts
  • 5x Ethernet ports
  • 2x Display ports (Not applicable to J7200)
  • 2x FPDlink display connectors (Not applicable to J7200)
  • 7x 3.5mm audio jacks
  • 2x PCIe connectors
  • SD card slot
  • 8GiB eMMC

Quad Port Ethernet daughter card

Quad Port Ethernet (QPENet) board is an adapter board which offers additional Ethernet port capabilities to the Jacinto7 EVM.

Contents of the board:

  • Quad-SGMII PHY
  • 4x Ethernet ports
  • EEPROM with flashed MAC addresses

GESI daughter card

GESI(Gateway/Ethernet Switch/ Industrial) daughter card is adapter board which has additional peripherals for gateway and industrial use cases. This has support for extra ethernet ports and CAN ports, etc

Contents of the board

  • 5x ethernet ports (NOT CONNECTED IN J7200, use QPENet daughter card for Ethernet)
  • Profinet connector
  • Motor control headers
  • Additional CAN Transceivers/headers

Switch settings

Most common boot method is to use SD card. Following are the switch settings to set the boot mode to SD for common processor board.

When you want the binaries to be loaded from a debugger like CCS, the common processor boards has to be set in the NO boot mode. Following are the switch settings to do the same.

EVM connections

Connect Following peripherals for working with processor SDK Linux

  1. MAIN_UART is a USB connector to connect 4x main UART devices, this will register /dev/ttyUSB[0-3] in your Linux machine.
  2. MCU_UART is a USB connector to connect 2x mcu UART devices. this will register /dev/ttyUSB[4-5] in your Linux machine.

Note

Connect the MAIN_UART and MCU_UART in order so that the device numbers are assigned correctly.

  1. Connect ethernet at the RJ45 connector[4] in the commonProcBoard as shown.
  2. Insert micro SD card at the slot shown in [5]
  3. Connect the XDS110 connector[6] if you want to run RTOS demos or use CCS.

Note

For Linux demos, keep the bootswitch settings in SD mode For Gateway demos, keep the bootswitch settings in noboot mode

  1. Connect a 12V power supply that outputs a minimum of 5A
  2. Power on the board
