Compulsive modification of HDMI output resolution
the final solution of compulsive modification of HDMI output resolution.
As you may have discovered the common configuration method in raspberry pi (such as alteration of /boot/config.txt) does
not work on BPI, neither does the modification of cmdline.txt and uEnv.txt especially for some display with converter(HDMI-
>VGA or HDMI ->IDVI) or some old display devices.
Today,we are introducing a new solution to modify the resolution of HDMI, no other risks if you do it according to this
document step by step:
1,install compile sunxi-tools depended-upon packages
sudo apt-get install libusb-1.0-0-dev
2,get sunxi-tools new code from github:
git clone https://github.com/linux-sunxi/sunxi-tools.git
3,compile sunxi-tools
cd sunxi-tools
make
4,backup script.bin
sudo cp /boot/bananapi/script.bin /boot/bananapi/script.bak
5,copy script.bin to current dir
cp /boot/bananapi/script.bin ./
6,use bin2fex change bin to fex
bin2fex ./script.bin ./script.fex
7,edit script.fex file:
nano script.fex
