Running the Player Demo Application on iMX6 Linux

iMX6 System Preparation

For instructions how to install the toolchain please refer to the Yocto Project's Quickstart and Application Developer's Guide.

Executing Target Player from the SD Card

The application and asset can be copied into the folder /root on the SD-Card with the target root file system, and executed like this:

# Connect TeraTerm to COM1 at
# bits per second: 115200 
# data bits: 8
# parity: none
# stop bits: 1
# flow control: none 
# load the GPU Driver
modprobe galcore.ko
cd /root
# run CGIApplication
./CGIApplication_ARM_Linux_iMX6_Target_GCC <AssetLibrary> 

Both applications use a target asset file.

Additional Steps for Frame Buffer Blending

If two display planes shall be blended on the iMX6 target, using Candera with the frame-bufffer implementation of the iMX6 drivers, following code can be used to resize and unblank the overlay plane. This is not avaliable if X11 is used.
