I found that the code always gets stuck at lv_event_send(obj, LV_EVENT_DRAW_MAIN, draw_ctx), and ultimately, it gets stuck at lv_draw_sw_rect. The call process of lv_draw_sw_rect is as follows:The program stuck in vg_lite_finish() in the functio...

如果没有使用硬件GPU的话,会被默认初始化成“lv_draw_sw_init_ctx”函数,这个函数中会将“draw_ctx”字段中的所有绘制回调函数都初始化成软绘(软件绘制)函数,软绘函数都是使用CPU进行绘制处理,如果有GPU的话,可以使用GPU绘制函数初始化“draw_ctx”。
