用ucos建立了五个任务，运行都正常，可是我加入了音乐播放，第五个任务就不运行了。

为什么我一加入了音乐播放的任务，屏幕的任务就不运行了呢？

zuozhongkai

MainTask();是哪个函数？

回复【2楼】zuozhongkai:
---------------------------------
是显示函数。

回复【2楼】zuozhongkai:
---------------------------------
我之前用的是4.5的一个SDIO然后加入mp3的话 是可以的，但是有的时候会卡在DMA里面，然后我又换成了4.4 的

注意SD卡读取数据的任务，我之前也是卡在这里

---------------------------------
读取数据的任务？能说具体一点吗|？

检查创建5th任务的状态返回值，再看OS配置文件。
