When I use the LVGL example with fb0, the fb0 device is found and initialized in /dev, but the error mentioned above occurs. I checked with dis and found that the specific address is 0x802d6e6c and the function is lv_timer_resume, but the error message is a data abort. How should I locate and resolve this issue?
