Hello All!

I use i.MX6UL Evk + LCD8000-43T.


If I load Yocto Linux, which was on microSD shipped with the EVK, everything is fine. First, i see on the LCD monitor a Uboot screen saver, then LInux Logo, then the Linux Graphical Shell.

Later I created an BuildRoot based Linux image - freescale_imx6ulevk_defconfig. But when it loading, on the LCD monitor  Uboot screen is displayed first, then LInux Logo and the blinking cursor and that's it. Further nothing changes and I do not see process of loading Linux on the LCD monitor.

I do not see an Linux Welcome after Linux is loaded on the LCD monitor. I can not enter commands from the keyboard.


But in the console I see that the Linux boot is proceeding normally.


My version of Linux does not have X11.


Note: via the console, I can display information on the monitor using the command
cat /dev/urandom > /dev/fb0
