with HDMI work not propber. HDMI does not work
Product: buildroot
Version: 2015.11
Hardware: PC

Building embedded Linux for Atmel SAMA5D4_Xplained with HDMI work not proper. HDMI does not work.
When I build with buildroot the images for the Atme SASMA5D4_Xaplined Board. inkl HDMI and fb0 HDMI will not work.
A already change the device tree to the correct dts file. However the fb0 is present in the rootfs under /dev.
I make a double check. I use the linux4sam demo Image 4.7 and flash it tto my EvalBoard. HDMI Works perfect. After this i build with buildroot. Board is booting everthing works but not HDMI.
And no the strange thing. I have replaced file for file from the demo linux4sam demo Image 4.7. Firts when i take from linux4sam demo Image 4.7 the at91bootstrap.bin the HDMI works.

Ok i habe investigated the problem. It depends on wrong clock. With the new bootloader the CPU clock is set to 600 MHZ. But the kernel does not handle this correct.

I've never had any luck all with linux4sam.com, and have given up using it. Questions are usually completely ignored. If there are any responses, they're usually way off base. You might as well walk down the street and ask panhandlers: it appears to be the clueless leading the incompetent. You might try contacting your Atmel FAE to see if he can help. There also used to be one or two knowlegable Atmel employees who participated in comp.arch.embedded, but that was several years ago.

The best way to contact kernel developers is to use the kernel mailing lists. For AT91, this is the linux arm kernel mailing list (lakml):
