I built the rootfs based on Jagan's instructions at https://openedev.amarulasolutions.com/display/ODWIKI/i.CoreM6+1.5 I tried building both the 4.15-RC6 kernel, a 4.19 kernel and a 4.14 LTS kernel. Using the suggested method of generating the graphical display of the pipeline options, I am able to enable various pipeline options connecting different /dev/videoX options tot he camera. I have tried both the suggested method above as well as the instructions found in Documentation/media/v4l-drivers/imx.rst for their respective kernels, and I have tried multiple options to capture through ipu1_csi1_capture, ipu2_csi1_capture, and ip1_ic_prepenc capture, and all yield a broken pipe. libv4l2: error turning on stream: Broken pipe ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could not read from resource. Additional debug info: gstv4l2bufferpool.c(1064): gst_v4l2_buffer_pool_poll (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: poll error 1: Broken pipe (32) I can hear the camera click when I start gstreamer and click again when it stops trying to stream. dmesg indicates a broken pipe as well.. [ 2419.851502] ipu2_csi1: pipeline start failed with -32 might you have any suggestions? thanks, adam
