4.2.1. J7200 EVM Hardware Setup¶
4.2.1.1. Description¶
The J7200 Evaluation Module provides an affordable platform to quickly start evaluation of Jacinto™ DRA8xx Processors and accelerate development for ADAS, Gateway and many other automotive applications.
The J7200 Evaluation Module consists of a SoM(System on Module) and a common processor board.
4.2.1.2. J7VCL SOM¶
System on Module is a small board which has the SoC specific socket and other important platform specific hardware like PMIC, DDR memory, etc
There are 2 variants. Following are the images of EVMs with different versions of SoM:
1. Alpha board (Note: these images show a J721E SOM, but the J7200 SOM will look identical with the exception of the SOM label)
Note
Alpha EVMs have “Interim PMIC” sticker on the SoM board.
Beta board
Note
Beta EVMs don’t have a “Interim PMIC” sticker on the SoM board.
Contents of the board
J7200 SoC
Power controller
4 GiB DDR RAM
OSPI NOR flash
Hyperflash
4.2.1.3. Common Processor Board¶
Common Processor Board is the main board which has peripherals to provide most common functionality. It allows to connect to different adapter cards.
Common Processor Board with ALPHA-SOM
Common Processor Board with BETA-SOM (Note: this shows a J721E SOM, but the Common Processor Board labeling is the same as if it was a J7200 SOM)
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
2x FPDlink display connectors
7x 3.5mm audio jacks
2x PCIe connectors
SD card slot
8GiB eMMC
4.2.1.4. 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
4.2.1.5. 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 headers
4.2.1.6. 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.
4.2.1.7. EVM connections¶
Connect Following peripherals for working with processor SDK Linux
MAIN_UART is a USB connector to connect 4x main UART devices, this will register /dev/ttyUSB[0-3] in your Linux machine.
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.
Connect a Display Port 1080p monitor to the Display0 port of the commonProcBoard.
Note
Only the monitor with preferred resolution as 1080p shall be used, any other resolution is not supported.
Connect ethernet at the RJ45 connector[4] in the commonProcBoard as shown.
Insert micro SD card at the slot shown in ][5]
Connect the XDS110 connector[6] if you want to run RTOS demos or use CCS.
Connect a 1080p HDMI monitor to the HDMI port[7] port on the Infotainment daughter card.
Note
For Linux demos, keep the bootswitch settings in SD mode For Gateway demos, keep the bootswitch settings in noboot mode
Connect a 12V power supply
