  RUNNING THE CODE YOU BUILT ON THE BOARD 

9.0

 

There are three ways to take the image files you built in Section 5.0 and run them on the RPS:   

 

Write image to an SD card 

(1)

 

Copy the SD card image 

(2)

 

Setting up NFS to link to your development PC 

(3)

 

9.1

 

 Method 1:  Write Image to an SD Card 

 

First you must create an SD card image by running the command: 

(1)

sudo bin/z3-create-sdcard-img.sh  

This will create the image file  

images/z3-emmc.img 

 

Obtain a microSD card 4 GB or larger in size. 

(2)

 

You can write to the microSD card using either Linux or Windows. You will need to have an SD card 

(3)

reader to access the SD card. 

(a)

 

Linux method:

 use the install script shown below. 

*Note:

 You need to replace

 

sdd

 with your SD card block device.

 

 

sudo umount /dev 

ssd

* 

sudo bin/z3-install-sdcard-img.sh images/z3-img   

/dev/

sdd

 

 

If you don't know which device to use, this command will list all the removable devices: 
 

 lsblk -d -o NAME,RM | grep '1$' 

  
 
If there is more than one item in the list, then re-run the command with the SD card 
removed, then re-insert the SD card and run the command a second time. Whichever 
device is new the second time will be the SD card device. 

(b)

 

Windows method:

 Review this TI wiki post for instructions on burning the SD card image 

in Windows: 

http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Creating_a_SD_Card_with_
Windows

  

 

9.2

 

 Method 2:  Copy the SD Card Image to Internal eMMC Flash 

 

Follow the steps in Section 9.1 to write the SD card image. 

(1)

 

Power down the Z3-AM572x-RPS.
