Framebuffer display problem
I use an Angstrom kernel 2.6.32 build with openembedded on a DM6446 processor.
When I write an RGB565 bitmap image to the framebuffer (OSD0 layer) than the displayed
image is somehow distorted. You can see this especially in the text. It looks like if there is some
uncorrect offset when the driver displayes the second frame of the image.
I use the following bootparameters to initialize the framebuffer driver:
The displaying of images works perfectly with an old Montavista kernel. I have looked for
specific driver options but didn't find nothing which did really help. Any suggestions where I
could look or what could be wrong?
The issue was caused by the hardware bug 1.3.8 in the TMS320DM6446 of revision 1.1. The bug fix
was not merged in the current driver of the Angstrom kernel 2.6.32.
