Error occured when testing g2d on ubuntu imx6dl

[franklee19731]

Hi All,

  I tested g2d blitting on Ubuntu imx6DL, but there is an error as follows:

g2d_blit_2d: fail with status -20

I do not know what "status -20" means, so I have no idea how to do next.

The C program and Makefile is in the attachment.

thanks

Frank

Qiang Li,

I need this test program for IMX6SL which does not have IPU.

Is there a program to verify this ?

Hi Fetch, it can be supported on iMX6SL too, this is 2D feature and the iMX6SL has the GPU 2D too.

Hi Frank, you should not use malloc to prepare the G2D buffer, it needs physical continued memory.

Please reference to attached sample code.

Thanks! You are right, g2d should use physical address.
