Texas Instruments

Attaching an optional expansion card

Expansion cards can be added to the common processor board to expand the capabilities  
of the EVM.

• 

Automotive Gateway/Ethernet Switch /Industrial Expansion card

: this card adds ports for  

CAN-FD, Gigibit Ethernet and industrial Ethernet protocols. 

(Installation instructions are covered in the 

Appendix)

Step 2: Experiencing the Out Of Box (OOB) 

demonstration to ensure the EVM hardware is 

functional 

1.

 To turn on the EVM, move the SW2 switch to the ‘ON’ position, as shown in Step 1, #9 above.

2.

 Within seconds, you should see the linux uboot and kernel boot log on the PC terminal application 

you setup in Step 1, #6 above. 

3. 

When the boot completed, type “root” at the prompt to login and have access to the linux 

filesystem. 

Step 3: Download and install Processor SDK  

(software development kit) 

Processor SDK RTOS (PSDK RTOS)

 and 

Processor SDK Linux (PSDK Linux) 

together form a 

multi-processor software development platform for the Texas Instruments Jacinto 7 family of SOCs. 
The SDK provides a comprehensive set of software tools and components to help users develop and 
deploy their applications on supported Jacinto processors.

Processor SDK installation instructions are available online:
  Processor SDK RTOS: 

www.ti.com/DRA821PSDKRTOSInstall

  Processor SDK Linux: 

www.ti.com/DRA821PSDKLinuxInstall

From these links, you can learn how to install the SDK, modify, build, load, and debug the released 
software on the EVM.
