f1c100s+rtt+lvgl8.0出现了诡异的问题,之前用lv6.1的时候一切正常,然后因为要用到旋转功能,就用了8.0,结果发现一个诡异的问题
static void thrd_LVGL_Loop(void *parameter)
{
    while (1)
    {
        //rt_kprintf("thrd_LVGL_Loop1\n");
        lv_task_handler();
        rt_thread_delay(10);
        //rt_kprintf("AutoIncData=%d\n", AutoIncData);
    }
}

在rtt任务中,只要调用rt_thread_delay(x)就会出错,把tr_thread_delay注释掉就一切正常,报错的串口输出如下
