IMX6DUAL IPU ERROR

[alessandroinnoc]

Hi to all !

I got a strange behavior on my IMX6D using kernel 3.14.38;. The main application generates a rtp stream using  imxvpuenc_h264 element of gstreamer-1.0 framework. Once this application started, any access to the IPU, for istance using the imxipuvideosink element, is not possible.

The kernel's log shows the following messages:

[  433.836103] imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x02000000

Does any one faced (and possibly solved) such error ?

Thanks a lot !
