Our customer is using our official Android 2.3 BSP for iMX53QSB provided by Adeneo.
They are porting this BSP to their hardware, the work is almost done, but there are some issues on the video playback, it seems the framebuffer overlay is not working as expected.
- They start video reproduction - works fine
- At the end of the playback, the screen turns dark and the system seems to Freeze for the user.
- Doing tests, we found out that running the command echo 0 > /sys/class/graphics/fbX/blank in order to unblank the screen works fine.
So it looks like some driver is forcing a blank on the frame buffer after playback and no other driver unblanks it.
We did this exact same test with the QSB board, and the issue does not happen, it must be something on the porting.
The display in use is connected on the DI1 interface (not the LVDS or TVE).
Do you have an idea how to solve this?
I attach the code that was ported, note that the video_mode "QUANTA" was created for the new board.
