LCD4 (on BeagleBone) - ti-sdk-am335x-evm-5.6.0.0: display stays black

Hi

I've successfully installed the SDK on my Ubuntu, and created a SD card for my BeagleBone.

The BeagleBone has attached an LCD4 cape; it works fine if I use the included Angstrom SD card, booting up Gnome without problems.

But when I boot TI SDK, the screen stays black.

Matrix-gui is launched correctly at startup, altho the screen stays dark; while the manual says that the GUI demo should start at boot. I've tried to run the matrix-browser to see if anything would happen but the screen stay black, and I get an error :

QscreenLinuxFb::connect: No such file or directory

Error opening framebuffer device ./dev/fb0

Which makes me think that in fact, the LCD device was never found or initialized at boot (missing drivers?).

I've seen demo pictures of the TISDK running on BeagleBone with lcd cape, so I am not sure if I am missing something or did something wrong.

Any pointer would be really appreciate; thanks in advance.
