Hello guys I had time to dig into the kernel code and I discovered the origin of my problem. As I said in a previous post, we use a custom processor card based on a mpc8270. In the initialisation of our board was missing the following line :
conswitchp = &dummy_con; That's all ! Now it works fine. I still have a little problem : video output signals seems to be very low. I have to set the maximum contrast and luminosity to see something. I tried on different monitors, the problem is the same. The board is configured to use the rgb analog signals from the coral, not from the dac. Are there any jumpers or register to tweak the video signal levels ? I can't find it in the hardware manual...
