Gpu demo crashed under iMX6_SDK with iMX6DL

[laufei]

Hello, Freescale

I am using the iMX6_SDK to test the GPU demo based on the iMX6DL version.

By the way, I run this gpu demo successfully on the iMX6Dual version.

the following log shows the issue:

------------log-----------------------------

Can you help me check this issue?

Thank you very much.

This is "normal behaviour" of the SDK tests after exit,

assuming the GPU test is itself working.

Have a great day,
Yuri

Hi, Muhin

Thank you for your quickly reply.

When running the gpu demo, I didn't press anykey to exit the gpu demo, and the LVDS screen also shows mess info.

While using the iMX6Dual version, it's ok for showing the rolling ball.

I am thinking the SDK for gpu demo is not tested for iMX6DL version?

Thanks.

Best Regards

  The i.MX6 DQ and S/DL have different 3D hardware (Vivante GC2000 and GC880), therefore 

please try to rebuild the GPU test for target = mx6sdl.

Hi, Yuri

yes, I seleted the target is mx6sdl to build the GPU demo test other than  it can't print the console output.

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

make target=mx6sdl board=smart_device boardrev=c

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

can you help me check the sdk codes for this part?

Thanks.

[Yuri]

Sorry, I cannot get information, if the GPU demo was tested for i.MX6 S/DL.

~Yuri.

[Yuri]

  I do not have the i.MX6DL on hands to check the problem, sorry.

Let me try to know if app team tested the i.MX6DL.
I expect it may take a time.
