This article describes how to make Linux SD card which can boot system.


  • ROC-RK3328-CC Development board

  • Firmware

  • Linux Host Computer

Please refer to 《Build Kernel》 and 《Build Ubuntu Rfs》 instructions to compile partition images, or you can download here to obtain a unified firmware.

Process of Making Linux Boot Card

using SDCard Installer tools for windows

For windows users, you can select SDCard Installer tool ,to Download the tool:SDCard Installer

The SDCard Installer tool will be able to download ,burn and write the fireware in place,and the operation is simple and straightforward.

1、After inserting the SD card into the computer, open SDCard Installer.

2、Click the "Choose an OS"button, After selecting ROC-RK3328-CC,display the figure.


3、As shown in the figure, there are five choices:
    1) if there is no demand operating system in the local area, you need to download and select the operating  system you need. Click OK.
    2) if there is a local operating system with requirements, after clicking Browse image, select the system and click OK.

4、After completing the above steps, the computer also recognizes the SD card, clicks FLASH, and waits for completion.


Note: when the burn is completed to 99% or 100%, the following picture is presented, which can be ignored, and does not affect the firmware burning on the SD card.


5、After finishing the burn, the SD card will be removed from the computer and inserted into the TF card slot of rk3328,restart rk3328 is OK.

using scripts to make

you need to use Linux dd command to write the startup files into the SD card, the steps  are as follows:

  • Compile the kernel ,and u-boot:

see 《Build Kernel》

  • Make Ubuntu rootfs

see 《Build Ubuntu Rfs》

  • Synthesis system.img file for the production of the boot card  in the next step

build/ -c rk3328 -t system -r rk-rootfs-build/linaro-rootfs.img

Run the following command to write the unified firmware system.img generated above into the SD card:

build/ -c rk3328 -d /dev/sdb -p system -i out/system.img

using dd command to make

Here you also need to insert  the SD card to the computer

Run the following command to write the unified firmware system.img into the SD card:

pv -tpreb out/system.img | sudo dd of=/dev/sdb seek=0 conv=notrunc && sync

You can also run  the following commands to write a partitioned image into an SD card

sudo dd if=./out/u-boot/idbloader.img of=/dev/sdb seek=64      conv=sync,fsync 
sudo dd if=./out/u-boot/uboot.img     of=/dev/sdb seek=16384   conv=sync,fsync
sudo dd if=./out/u-boot/trust.img     of=/dev/sdb seek=24576   conv=sync,fsync
sudo dd if=./out/boot.img             of=/dev/sdb seek=32768   conv=sync,fsync
sudo dd if=./out/linaro-rootfs.img    of=/dev/sdb seek=262144  conv=sync,fsync
