Hi Eric, On the command line arguments I had dmfc=3. That was set to improve the IPU performance as I need to play up to 16 streams simultaneously. When I removed this option the boundary kernel is booting without the horizontal lines problem. HDMI to DVI is still not working.
cat /proc/cmdline console=ttymxc1,115200 video=mxcfb0:dev=hdmi,1920x1080@60 fbmem=24M,10M root=/dev/mmcblk0p1 rootfs=ext2 rw rootwait enable_wait_mode=off consoleblank=0 bpp=32 This is fine for know but it would be nice to understand why dmfc is conflict with boundary kernel. Also I'm not sure how is this going to affect the IPU performance! Hope you have an answer to this question so I can fully test the application. https://lists.yoctoproject.org/pipermail/meta-freescale/2013-December/005854.html Thanks, Tarek The command line argument doesn't help: console=ttymxc1,115200 video=mxcfb0:dev=hdmi,1920x1080@60 fbmem=24M,10M root=/dev/mmcblk0p1 rootfs=ext2 rw rootwait enable_wait_mode=off consoleblank=0 dmfc=3 bpp=32 Also On Tue, Dec 3, 2013 at 4:40 PM, Eric Nelson <[email protected] > wrote: > Hi Tarek, > > > On 12/03/2013 08:12 AM, Tarek El-Sherbiny wrote: > >> Hi Eric, >> >> root@nitrogen6x:~# cat /sys/class/graphics/fb0/modes >> S:720x480p-60 >> S:720x576p-50 >> S:1280x720p-50 >> S:1280x720p-60 >> S:1280x1024p-60 >> V:1024x768p-75 >> V:1024x768p-70 >> V:1024x768p-60 >> V:800x600p-75 >> V:800x600p-72 >> V:800x600p-60 >> V:640x480p-75 >> V:640x480p-72 >> V:640x480p-60 >> U:720x400p-70 >> D:1360x768p-60 >> D:1280x720p-60 >> V:640x480p-60 >> > > This looks like a pretty standard set of modes for a > 4:3 aspect ratio monitor. > > > root@nitrogen6x:~# cat /sys/class/graphics/fb0/mode >> S:1280x1024p-60 >> > > This doesn't match one of the CEA modes: > https://github.com/boundarydevices/linux-imx6/ > blob/boundary-imx_3.0.35_4.1.0/drivers/video/mxc/mxc_edid.c#L41 > > Can you boot with this command-line argument? > mxc_hdmi.only_cea=0 > > I think you'll either need that or you'll need to choose a > display resolution from the list.
