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
