Hi,
Our coustom board is based on i.mx53 & we are using linux 2.6.35.
We are using mxc_v4l2_overlay.out application to capture & display.
Everything works fine, but sometimes there is no data on display.
We found that when there is no data on display, there is no ipu interrupt generated.
In working/non-working case, the code flow is same & there is no error.
I am not sure why the ipu interrupt is not getting generated sometimes?
Please help us to understand the problem.
Thanks,
Praveen
Hi praveen,
If there is any issue, you should see some error/warning messages in your console, also make sure to enable the camera input modprobe mxc_v4l2_capture. I suggest to read Chapter 11 of you MX53 BSP documentation linux reference manual in order to check all options and usage of the ipu unit test codes.
Regards
