Hi Daniel

With the Raspbian OS image, I followed these steps

With the Ubuntu 16.04 OS image, I followed these steps:

List the installed bananapi packages

dpkg -l | grep bananapi

If you don’t see the bpi-tools package then download it from here and then install it as follows

The path shown below is wherever you downloaded the package to

For me, I downloaded the package to this path: /home/pi/Downloads/bananapi-bpi-tools_1.0.3_armhf.deb

sudo dpkg -i /home/pi/Downloads/bananapi-bpi-tools_1.0.3_armhf.deb

List the installed bananapi packages again, if the install was successful, you’ll now see the bpi-tools package

dpkg -l | grep bananapi

Check that you have the following file


To check, run the following command

ls -la /usr/lib/u-boot/bananapi/bpi-m3

Once confirmed that you have the file, then run the following command from the command shell to change resolution to 1080

sudo bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m3/BPI_M3_1080P.img.gz

Once complete then run

sudo reboot now

You should now have 1080 resolution once the Pi boots back up

The steps above were carried out with the Pi plugged into a monitor via HDMI

Hope this helps

thanks for your reply

the steps to change the resolution are helpful. now the bpi runs in 1080p.

but how can i move the root-partition from mmcblk0p2 to sda3?
