Issues with U-Boot 2014.01 Splashscreen/Linux Framebuffer

Hi,

 

i have some problems with enabling framebuffer support at the kernel command line with U-Boot 2014.01 (with the nice splash screen) on an i.MX6Q Sabre SD board with yocto Linux.

 

When changing

mmcargs=setenv bootargs console=\${console},\${baudrate} root=\${mmcroot}

to

mmcargs=setenv bootargs console=\${console},\${baudrate} root=\${mmcroot} video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32

the Linux kernel stops at "Starting kernel..." if a monitor is connected to HDMI.

If the HDMI is unconnected, the kernel starts without problems.

 

By now I use a patch to remove the framebuffer related defines from [u-boot-dir]/include/configs/mx6sabresd.h, but cannot be the final solution.

 

Does anyone else have similar issues?

 

 

Bye,

Martin
