Hi, you are using an IMX8 QM board with imx-yocto-L4.14.78_1.0.0_ga release, right? I am trying to boot an image on my IMX8qmlpddr4arm2 board with sumo but this image can't boot. I have reproduced the steps on the yocto manual but I do not know why it fails Did you have this kind of problems?
Sorry for this out of topic question but I have not found tellthebell informations that could help me yet.
Thank you, and sorry for bad english.
hello,
When I changed to gst-launch-1.0 below error:
Setting pipeline to PAUSED ...
Caught SIGSEGV
exec gdb failed: No such file or directory
Spinning. Please run 'gdb gst-launch-1.0 4092' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
Thanks
pls run "gdb gst-launch-1.0 4092", then debug the issue, if you just want to test camera, you can use unit test, under /unit_test/V4L2, then use the mxc_v4l2_overlay.out, then pls ensure you connect hdmi to your board already
