Hi Freesacle

 

In android 6.0.1, I try to open camera app and test camera function.

Cpu is MX6Q.Our camera is ov5640.  That is the same with demo board.

We are not used front end camera. So I disable front camera in "init.i.MX6Q.rc".

 

[Question 1]

step1

Our uboot setting: 

--------------------------------------------------------------------------------------------------------------------------------------------------------

setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=256M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M

--------------------------------------------------------------------------------------------------------------------------------------------------------

When I open camera, system always show IPU Warning in debug port.

The system can not preview from camera.

-------------------------------------------------------------------------------------------

imx-ipuv3 2800000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x00800000

imx-ipuv3 2800000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00100000

imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000

imx-ipuv3 2800000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x00800000

imx-ipuv3 2800000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00100000

imx-ipuv3 2800000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x00800000

imx-ipuv3 2800000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00100000

imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000

imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x00800000

-----------------------------------------------------------------------------------------------

And HDMI port is on / off.

 

 

step 2

If I change frame buffer output to LVDS, system show IPU Warning in debug port.

--------------------------------------------------------------------------------------------------------------------------------------------------------

setenv bootargs console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,800x480M@60,bpp=32,if=RGB24 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=256M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M

--------------------------------------------------------------------------------------------------------------------------------------------------------

The system can preview from camera.

 

After 30 sec, system can not preview from camera.

system always show IPU Warning in debug port.

imx-ipuv3 2800000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x00800000
