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.
Hi,
what is your error log?
Thanks
if you don't define GSTL, try to use gst-launch-1.0 to instead of GSTL
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
hello,
I used the unit test mxc_v4l2_overlay.out,and log shows:
---- Running < ./mxc_v4l2_overlay.out > test ----
g_display_width = 240, g_display_height = 320
g_display_top = 0, g_display_left = 0
sensor chip is imx8_max9286_mipi_0
VIDIOC_S_OUTPUT failed
what is the problem?
if you use 9286, you can refer to the document as below:
yes,I only want to test camera,please give guide about test camera that I used SAS cable with MAX9286 connect four OV10635
Thanks
