EBA0 is not 8-byte aligned error on imx6

[alokkumar]

Dear All,

I have been "EBA0 is not 8-byte aligned" error and not sure what it means.

Does this mean my display window should be 8 byte aligned 640x480 etc or size of file should be dividable by 8 ?

That is correct. Non 8 pixel aligned width and height is treated as not supported format in isink plugin. BTW, have you tried this on latest BSP (4.0.0)?

There is another artifact which we are investigating and happens when displaying >1080p images on a HDMI display. Let me know if this is your test case.

Leo

[alokkumar]

Hi Leo,

I think I experience both issues. I noticed a jpeg file of 3264x2448 pixel had issues in display and image was split multiple times on display. When I down sampled to 1080P, it seems to work.

I am using latest from timesys, could you please let me how to check the BSP.

[LeonardoSandova]

Hi Alok,

For the >1080p issue on HDMI, it is a known issue and we are working to fix it. BTW, how did you downscale the image? A pre-processing step?

Last week, a new release for MX6Q SABRE boards was delivered (3.0.35_4.0.0), so let me check with this version these two issues. I will update this thread ASAP.

Leo

[alokkumar]

Hi Leo,

I am surprised to see this error on a 640x480 pixel file and even the display of 640x480.

Please see the gst-launch pipeline below.

[LeonardoSandova]

Interesting. Are you still using HDMI, right? These logs do not show up when displaying on LVDS, so it may be a rescaling issue done on the IPU.

Leo

[alokkumar]

Yes, I am using HDMI output.

I am surprised 640x480 pixel file and hdmi display of 640x480 (part of 1080P window).

Is there any adverse performance impact of this.

Thanks

Alok

[LeonardoSandova]

Alok, Could you try the above patch and let me know if issues (ipu logs and wrong image display) went away?

Hi, i met this issue also, have you fixed this issue with change sets of "LeonardoSandovalGonzalez" ?

thanks

[XXiao1z]

same issue persists with this patch, on 4.1.0 release with all newest patches from git.freescale.com

is this harmless or serious?

keep seeing this on serial console concerns me, but I'm not sure how bad they really are:

why am I seeing ipuv3.0 and ipuv3.1 two versions?

Hi Alok. We are investigating this issue. I will update this thread ASAP.

I get the same warning when I use the v4l2src plugin (not mfw_v4lsrc) when streaming from the ov5642 camera on a sabrelite (using mxc camera interface). I don't get this warning if my sink is a file. I only get it when the sink is mfw_v4lsink (i.e. display). I am running 3.0.35_1.1.0 (yocto dylan). I also don't get this issue when using the mfw_v4lsrc plugin.
