Because the Banana Pi comes with a SATA connector it offers you the possibility to hook up an SSD or other hard drive. In that context it even provides a 5V power connector allowing you to power an SDD right from the board. Just be cautious with the power connector’s polarity, I had to switch the wires of my SATA power cable to get things right!
Move the rootfs to a SATA Drive
Currently it’s impossible to boot from a SATA drive without a SD card. You will still need a small SD card for the bootloader. However, it is possible to adjust the bootscript (which is similar to a bootloader) on the SD card so that it points directly to your SATA drive. This way your system will boot the OS right from the SATA drive.
Here’s what you have to do:
Note: all this commands require root privileges.
- Connect your SSD (of course :-) )
fdisk -land identify your SATA drive. In this example
/dev/sdarepresents the SSD disk.
Prepare your disk
- Delete all partitions using the “d” option
- Create a new primary partition using the “n” option (you can accept all the defaults)
- Use the “w” option the apply the changes.
Format the partition for rootfs with EXT4 filesystem
I still assume that
/dev/sda represent the SATA drive
mkdir /tmp/1 /tmp/target mount /dev/mmcblk0p2 /tmp/1 mount /dev/sda1 /tmp/target (cd /tmp/1; tar --backup -c *) |tar -C /tmp/target -xv
Change the kernel parameters in order to boot from the SSD drive
mkdir /tmp/boot mount /dev/mmcblk0p1 /tmp/boot vim /tmp/boot/uEnv.txt
Change the last line to:
.. root=/dev/sda1 ...
Sync to disk and reboot to your hard drive
You can test the result with:
