I am using BPI M2-zero with the latest raspbian os available for bpi-M2-zero . I need to connect it to a 3.5 inch display using hdmi cable for which I need a resolution of 480x320 . Also in BPI-M2 I found only one image file under /usr/lib/u-boot/bananapi/bpi-m2z which is BPI-M2Z-720P-linux4.4-8k.img.gz. How can I get other image files to achieve different resolutions on a raspbian os.
Thank you .
