AM3517EVM Rotation + Resize issue

Information is very limited to conclude anything, Do you have any other symptoms? What do you mean, freezing occurs? Is it only console freeze OR whole system got frozen?

What is this patch you are referring to?

Also, there are various fixes we have done on top of PSP 04.02.00.7 release, I recommend you to migrate the kernel to -

http://arago-project.org/git/projects/?p=linux-omap3.git;a=shortlog;h=refs/heads/OMAPPSP_04.02.00.07

Can you check with above kernel?

Thanks,

Vaibhav

Thank you for your reply.
Here is additional information.

It is whole system freezing, because it cannot recover
without the power restart or H/W reset.

And the patch means exactly the kernel you recommended.
My customer uses this kernel.
http://arago-project.org/git/projects/?p=linux-omap3.git;a=shortlog;h=refs/heads/OMAPPSP_04.02.00.07
I am sorry my explanation made you confused.

Sample code: "saUserPtrLoopBack.c"  in SDK 05.03.02
Command:     ./saUserPtrLoopback -i 0 -l 1000 -x 0 -y 0 -X 456 -Y 342 -a 0 -b 0 -c 720 -d 480 -r 270

If you need more infomation, please let me know.

I appreciate your help in advance.

Dear All,

I am working on AM3517 omap3 controller. Problem is with display. Display is getting rotated in 180 degrees  and from 180  to 0 degrees without any problem but when i tried to rotate display either to 90 or 270 degrees following is the error.

"detected fb_set_par error, error code: -22"

  Rotation commands are in following site: http://omappedia.org/wiki/Bootargs_for_enabling_display

I tried rotating display in all directions i mean 90, 180, 270 degree rotation.
Display is getting rotated in 180 degrees but i am unable to rotate to 90 & 270 degrees
when i dig through kernel code i came to know that this is because of overlay failure
    
    ovl->setup_overlay_info failed
     setup_overlay failed
     apply_changes failed
     detected fb_set_par error, error code: -22


 Default rotation applied to all framebuffers.
      0 - 0 degree rotation
      1 - 90 degree rotation
      2 - 180 degree rotation
      3 - 270 degree rotation
