Hi.

 

The following error occurred when I tried to stream video from two cameras(720p@60fps) with gstreamer.

"mx6s-csi 30a90000.csi1_bridge: mx6s_csi_irq_handler Hresponse error detected"
(BSP : 4.9.51_imx8m_ga)

And the frequency of occurrences is 1-2 in five on average.

 

For this error, I had checked the file that 'drivers/media/platform/mxc/capture/mx6s_capture.c', and I got It occurs when the bit BIT_HRESP_ERR_INT is on.

 

So, I want to know the meaning of this error and the information of CSI_CSISR register or the solution for this error.
(I couldn't found the meaning of this error and information of CSI_CSISR in any manual for i.mx8.)

 

Thanks!
