Problems with HDMI output (ti8148)

Hi,

I have a problem regarding HDMI with my ti8148 eval board using the EZSDK 5.02. Currently, I can boot the Linux
system over TFTP and NFS, but when I try to start Qt applications I get the following error:
QLinuxFbScreen::connect: Inappropriate ioctl for device
Error reading fixed information
The standard UI application does not start either (but it is Qt, too, so this should be "normal"). I
have changed the video mode to HDMI and I have also tried to set different resolutions (and I did the
reboot step, too). The screen is connected with an HDMI-to-DVI-cable and it behaves as if no signal
is coming to it. Since I could not figure out what the Qt message means I checked
the dmesg output (see below). The reason seems to be that the ti81xxhdmi-driver crashes (at the end
of the log). What is the reason? Is it necessary to debug the driver? How can I get the output
working? Please do not say that I need to debug the driver.
Best regards,
Markus
