My customer is trying to display with overlay, but it does not go as expected.
The customer is using i.MX6Q-SDB board, and they are using LinuxBSP(Yocto3.14.28).
They are using HDMI display port and decoded 1920x1080 video is flow out.
They want to overlay graphical data image which was drawn on fb1 to the HDMI output. When the resolution of fb1 is 1280x720, the overlaying goes as expected.
But when the resolution of fb1 was 1920x1080, then the overlaying did not work.
And the following warning messages were seen.
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x08000000
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000
BTW, fb0 has the same resolution(1920x1080) as fb1.
The information of fb0 is as below.
root@imx6qsabresd:/mnt/work# fbset -fb /dev/fb0 mode "1920x1080-60"
# D: 148.500 MHz, H: 67.500 kHz, V: 60.000 Hz
geometry 1920 1080 1920 3240 16
timings 6734 148 88 36 4 44 5
Could you show me how to achieve that?
