Radxa - SD Images

SD Images

SD images for the rock are images booting and running on the uSD card completely. This is good when you want to try different OS or new version of the firmware without touching the nand flash.

Downloading SD Images

Check your hardware revision (Pro or Full/Lite), then download image "for SD card" from here

Writing SD image to SD card

Windows

See the readme in the individual image zip file for additional information on which tool to use.
Before beginning, you will need to prepare a high quality SD card of at least 8GB. A poor quality SD card will result in boot failures.

• Download the Win32DiskImager from here.
• Download the image from above link.
• Use the Win32DiskImager to Write the image into SD card

 

Linux

We use dd in Linux to write the image:

   sudo dd if=radxa_rock_xxxx_sdcard.img of=/dev/sdx              # x is the disk name of your uSD card on your PC

Mac OS X

We use dd and Apple's diskutil utility to write the image:

1. Run diskutil list to determine the drive associated the SD card (ex: /dev/disk4)
2. Unmount the existing disk sudo diskutil unmountDisk /dev/diskX where X is the disk name of your uSD card on your PC
3. Write the image file to the uSD card sudo dd if=radxa_rock_xxxx_sdcard.img of=/dev/diskX where X is the disk name of your uSD card on your PC

Booting to SD Card

1. Power off the Rock
2. Insert the SD card
3. Power on the Rock and it will boot to the SD card
