Hi All.

I try build system i.MX53 ( qsb-board) with GPU.

I build BSP with Yocto - Rocko , Sumo , Thud , Warrior , Zeus.

I see GPU does not work.

 

After that I build kernel 5.4 with Yocto - Rocko , Sumo , Thud , Warrior , Zeus.

GPU does not work.

In addition, I see , we have problem with  X11.

I see xorg.conf file ,

 

Section "Device"
Identifier "i.MX Accelerated Framebuffer Device"
Driver "imx"
Option "fbdev" "/dev/fb0"
# This option only recognized when "mxc_epdc_fb" frame buffer driver in
# use. Values are "RGB565" (default, 16-bit RGB), "Y8" (8-bit gray),
# and "Y8INV" (8-bit gray inverted).
Option "FormatEPDC" "Y8INV"
EndSection
 

, we have problem.

 

If we change  : Driver "imx" to Driver "fbdev" , Xort is working.

I think no work GPU accelerator.

Maybe someone launched the GPU on i.MX53.

Best regards.
