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
Solved! Go to Solution.
I'll give it a try.
But the linked thread describes a different problem (freeze with HDMI disconnected - in my case the kernel freezes with HDMI connected).
EDIT: Did not work...
EDIT2: It is a known bug: https://bugzilla.yoctoproject.org/show_bug.cgi?id=6703
Hi Marcel,
This is a kernel issue.
Could you please try the proposed fix in this thread?
i.mx6Q custom board, keep interrupt and hang.
Please let us know if this solves the issue.
I'll give it a try.
