I have flashed Pico Plus Buildroot image to my Mini B. I have ran rknn-st7789 releated examples that provided by luckfox-github team and it worked! But there is a catch: my screen is 240x135 BUT presets are 240x320 and i have not managed to change it by any chance. Can you help me?

Note: Changing fbtft pins on "rv1103-luckfox-pico-ipc.dtsi" did the trick (since two boards runs on a same chip)

Hello, the screen resolution used in the source code of the luckfox_pico_rknn_example repository is the resolution of the framebuffer registered by the driver. Modifying the resolution can be done by directly modifying the driver source code or the disp_width or disp_height in luckfox_pico_rknn_example. For details on the modifications, please test and determine on your own.

By default in driver, how can i change resulution system widely with compiling buildroot again? Which source should i tweak

The resolution setting is handled by the kernel driver and has nothing to do with Buildroot. Without modifying the driver, what you need to change is the disp_height and disp_width in the source code of the program you are running.
