Hello,

Please try to restart the matrix GUI and weston:
#/etc/init.d/matrix-gui-2.0 stop
#/etc/init.d/weston stop
#/etc/init.d/weston start
#/etc/init.d/matrix-gui-2.0 start

Check this chapter in the guide:
processors.wiki.ti.com/.../Processor_Linux_SDK_Graphics_and_Display

You could add these lines in weston.ini also:

[core]
require-input=false

Hope this helps.

BR
Margarita

You need to connect an USB pointing device.

Hi Biser,thanks for you input here,we insert one mouse with usb, but there's nothing to change. we fond that if we boot the kernel from sd card ,the matrix will be opened automatically,if we boot from the emmc,it always display "Please wait ....".how this happened?

Hi Biser,we made the emmc filesystem used the filesystem in SD card, the matrix display work well now,we guess the filesystem in emmc is broken somewhere. thanks.
