what's your detail kernel version and configuration?

Not a bug we can fix in the driver:

Fix Your application – This is a RGB24 BGR24 issue.

The driver only supports one color format.

 

Any applications should retrieve the available color format from the driver and

then use the offsets accordingly.

Hi,

 

ok, you were right.

Qt-embedded doesn;t handle the offset for RGB.

Instead, the color permutation is handled at the application level by calling

QImage swapRGB() function which performs the swap.

It is not really efficient but the bug can be closed

 

 

David.
