Rock Pi 4 Tutorials : ROCK Pi 4 Backup and Restore uSD card or eMMC module

Using Windows

One of the best tools to backup and restore SD cards is Win32 Disk Imager. Download it from SourceForge and install it. BEFORE starting the software, insert your SD card into the SD card reader on your PC. Often this will open the file explorer showing you the contents of part of your SD card, which should look something like this:

This is not the whole of the contents of your SD card – only part of the card contents is readable by Windows. The rest is not readable by your PC.

Once you open Win32 Disk Imager, use the blue folder icon to choose the location and the name of the backup you want to take, and then choose the drive letter for your SD card.

Click on the Read button. The card will then be backed up to your PC.

If you have a problem with your SD card and it becomes unreadable for any reason (e.g. it becomes corrupted), just follow the above instructions, choosing the image you created as the image file, and click on Write to write it back to the SD card. In fact, you can write it back to another SD card of the same size, giving you an exact duplicate.

Using OSX

Insert the SD Card into a card reader on your Mac. Open Terminal and enter the following command to locate your SD Card:

diskutil list

All your disks will be listed, and will look something like below:

Look for your SD card by looking for a disk of the right size and name. In the above example, the SD Card is /dev/disk1.

Next, in Terminal, enter the following command to create a disc image (.dmg) of your SD Card in your home directory.

sudo dd if=/dev/disk1 of=~/SDCardBackup.dmg

Wait until the SD card has been completely read; the command does not show any feedback, so wait for the command prompt to reappear in the terminal window once it is complete.

Again, if you corrupt your SD card or need to make a copy at any time, you can restore it by following the same approach as above to locate your SD card. Before you can write to the card you have to ‘unmount’ it so that the operating system does not try to write to it at the same time. Use the following in the Terminal:

diskutil unmountDisk /dev/disk1

Then use the this to write the image back to the SD card:

sudo dd if=~/SDCardBackup.dmg of=/dev/disk1

Once it has finished writing the image to the SD card, you can remove it from your Mac using:

sudo diskutil eject /dev/rdisk3

Using Linux

Before inserting the SD card into the reader on your Linux PC, run the following command to find out which devices are currently available:

df -h

Which will return something like this:

Filesystem 1K-blocks Used Available Use% Mounted on rootfs 29834204 15679020 12892692 55% / /dev/root 29834204 15679020 12892692 55% / devtmpfs 437856 0 437856 0% /dev tmpfs 88432 284 88148 1% /run tmpfs 5120 0 5120 0% /run/lock tmpfs 176860 0 176860 0% /run/shm /dev/mmcblk0p1 57288 14752 42536 26% /boot Insert the SD card into a card reader and use the same df -h command to find out what is now available: Filesystem 1K-blocks Used Available Use% Mounted on rootfs 29834204 15679020 12892692 55% / /dev/root 29834204 15679020 12892692 55% / devtmpfs 437856 0 437856 0% /dev tmpfs 88432 284 88148 1% /run tmpfs 5120 0 5120 0% /run/lock tmpfs 176860 0 176860 0% /run/shm /dev/mmcblk0p1 57288 14752 42536 26% /boot /dev/sda5 57288 9920 47368 18% /media/boot /dev/sda6 6420000 2549088 3526652 42% /media/41cd5baa-7a62-4706-b8e8-02c43ccee8d9

The new device that wasn’t there last time is your SD card.

The left column gives the device name of your SD card, and will look like ‘/dev/mmcblk0p1’ or ‘/dev/sdb1’. The last part (‘p1’ or ‘1’) is the partition number, but you want to use the whole SD card, so you need to remove that part from the name leaving ‘/dev/mmcblk0’ or ‘/dev/sdb’ as the disk you want to read from.

Open a terminal window and use the following to backup your SD card:

sudo dd if=/dev/sdb of=~/SDCardBackup.img status=progress

The dd command will show the progress, you just need to wait until the command prompt re-appears.

To restore the image, do exactly the same again to discover which device is your SD card. As with the Mac, you need to unmount it first, but this time you need to use the partition number as well (the ‘p1’ or ‘1’ after the device name). If there is more than one partition on the device, you will need to repeat the umount command for all partition numbers. For example, if the df -h shows that there are two partitions on the SD card, you will need to unmount both of them:

sudo umount /dev/sdb1 sudo umount /dev/sdb2

Now you are able to write the original image to the SD drive:

sudo dd bs=4M if=~/SDCardBackup.img of=/dev/sdb status=progress

The bs=4M option sets the ‘block size’ on the SD card to 4Meg. If you get any warnings, then change this to 1M instead, but that will take a little longer to write.

Again, wait while it completes. Before ejecting the SD card, make sure that your Linux PC has completed writing to it using the command:

sudo sync

Rock Pi 4 Tutorials : ROCK Pi 4 Linux system runs on M.2 NVME SSD

Prerequisites

To follow this tutorial, you will need:

A well-running ROCK Pi with eMMC or Micro SD Card

Linux system image for ROCK Pi 4

SPI Flash image (ROCK Pi 4 u-boot image)

SPI Flash IC on ROCK Pi 4 Single power supply voltage range: 2.7~3.6V Space: at least 4MB



M.2 NVME SSD with M.2 NVMe SSD Reader Adapter Support brand: HP, Intel, MaxMemory, KingSpec, etc



Step 1 Install ROCK Pi 4 u-boot image to SPI Flash

There are two methods for installing u-boot image to SPI Flash.

Method One: Write image to SPI flash from USB OTG port

Fitrstly, Get ROCK Pi 4 u-boot image from here

Select the target files, called uboot-trust-spi.img and rk3399_loader_spinor_v1.15.114.bin .

Then just follow Write image to SPI flash from USB OTG port to flash image.

Method Two: Write image to SPI flash using mtd tool

This method requires a running system on ROCK Pi 4 board. So now power on the ROCK Pi 4. Maybe your ROCK Pi system is running on eMMC module or uSD card. It is OK.

Firstly, add Radxa APT source. The latest version of u-boot and kernel are still in testing.

For Debian stretch

$ export DISTRO=stretch-testing # update more frequently but maybe unstable $ echo "deb http://apt.radxa.com/$DISTRO/ stretch main" | sudo tee /etc/apt/sources.list.d/apt-radxa-com.list

or Ubuntu server

$ export DISTRO=bionic-testing # update more frequently but maybe unstable $ echo "deb http://apt.radxa.com/$DISTRO/ bionic main" | sudo tee /etc/apt/sources.list.d/apt-radxa-com.list

Get the pub key

$ wget -O - apt.radxa.com/$DISTRO/public.key | sudo apt-key add -

Update APT

$ sudo apt-get update && sudo apt-get upgrade

Install necessary packages

$ sudo apt-get install -y rockchip-fstab $ sudo apt-get install -y rockchip-overlay $ sudo apt-get install -y rockpi4-dtbo $ sudo apt-get install -y linux-4.4-latest # Will update kernel $ sudo apt-get install -y rockpi4b-rk-u-boot-latest # Will get the newest version of u-boot package, but not update the u-boot on eMMC or uSD card

Modify file, /boot/hw_intfc.conf. Uncomment these lines.

intfc:uart4=off intfc:spi1=on intfc:dtoverlay=spi1-flash

Reboot the machine.

After login, there is a device /dev/mtd0.

Since we have done a lot of preparation, now it is time to install the image to SPI Flash. Just follow the commands.

$ sudo /usr/local/sbin/rockpi4b_write_spi_flash.sh

After that, something are shown to us.

Doing this will overwrite data stored on SPI Flash and it will require that you use eMMC or SD as your boot device. Type YES to continue or Ctrl-C to abort.

We follow its suggestion and type YES. Now we just wait until the installation job is done.

Step 2 Install ROCK Pi 4 system image to M.2 NVME SSD

It is convenient to install system image to M.2 NVME SSD.

Put the M.2 NVME SSD into M.2 NVMe SSD Reader Adapter, and then insert them to PC.

When they are ready, use tool command dd or APP Etcher to install system image to M.2 NVME SSD.

Step 3 Test M.2 NVME SSD booting from SPI Flash

Power off ROCK Pi 4, remove eMMC module or uSD Card from ROCK Pi 4 since there is system image in eMMC module or uSD Card.

Insert M.2 NVME SSD into ROCK Pi 4.

Power on ROCK Pi 4.

What is Armbian ?

Armbian is a base operating system platform for single board computers that other projects can trust to build upon.

Lightweight Debian or Ubuntu based distribution specialized for ARM developing boards.

Each system is compiled, assembled and optimized by Armbian Build Tools

It has powerful build and software development tools to make custom builds

A vibrant community.

Common features

Debian or Ubuntu based. Compiled from scratch,

Install images are reduced to actual data size and resized at first boot,

Root password is 1234 . You are forced to change this password and create a normal user at first login,

. You are forced to change this password and create a normal user at first login, Ethernet adapter with DHCP and SSH server ready on default port (22)

Wireless adapter with DHCP ready if present but disabled. You can use armbian-config to connect to your router or create AP

NAND, SATA, eMMC and USB install script is included (nand-sata-install)

Upgrades are done via standard apt-get upgrade method

Login script shows: board name with large text, distribution base, kernel version, system load, up time, memory usage, IP address, CPU temp, drive temp, ambient temp from Temper if exits, SD card usage, battery conditions and number of updates to install.

Performance tweaks

/var/log is mounted as compressed device (zram, lzo), log2ram service saves logs to disk daily and on shutdown

half of memory is alocatted/extended for/with compressed swap

/tmp is mounted as tmpfs (optional compressed)

browser profile memory caching

optimized IO scheduler. (check /etc/init.d/armhwinfo)

journal data writeback enabled. (/etc/fstab)

commit=600 to flush data to the disk every 10 minutes (/etc/fstab)

optimized CPU frequency scaling with interactive governor (/etc/init.d/cpufrequtils) 480-1010Mhz @Allwinner A10/A20 480-1260Mhz @Allwinner H3 392-996Mhz @Freescale imx 600-2000Mhz @Exynos & S905

eth0 interrupts are using dedicated core (Allwinner based boards)

How To use Armbian with Rock Pi 4

Check download page for recently released OS images.

Preparation Make sure you have a good & reliable SD card and a proper power supply. Archives can be uncompressed with 7-Zip on Windows, Keka on OS X and 7z on Linux (apt-get install p7zip-full). RAW images can be written with Etcher (all OS). Boot Insert the SD card into the slot, connect a cable to your network if possible or a display and power your board. (First) boot (with DHCP) takes up to 35 seconds with a class 10 SD Card. Login Log in as: root Password: 1234. Then you are prompted to change this password (US-Keyboard setting). When done, you are asked to create a normal user-account for your everyday tasks.
