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)
Mini B, framebuffer device, change resulution
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 tweakCrocodile wrote: ↑2025-05-30 1:10 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.

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.
