Deal NXP :

IMX6 

IPU camera 压力测试,

倒车模拟测试,即不停打开关闭camera, mxc_streamon(cam); 取多帧数据,刷在显示屏上以后, mxc_streamoff(cam);

这样测试下来,一天会出现多次定屏显示,卡在一帧camera图像显示上,很难恢复,内核出现如下LOG 

imx-ipuv3 2400000.ipu: warning: disable ipu dma channel 21 during its busy state

请问这种问题如何修复,期待您的解答,非常感谢。

4.1.15 is very old bsp, do you mind upgrading to the latest version?
