Hi guys,
I've been following this tutorial (http://shakithweblog.blogspot.com/2012/12/getting-sobel-filter-application.html) and everything worked great. In the tutorial they give you the BOOT.BIN file ready, so now I'm trying to generate the BOOT.BIN file by myself and I've got some errors :/
To generate the BOOT.BIN file I'm using Xilinx SDK and three files: zynq_fsbl.elf, system.bit and u-boot.elf. These three files are the same as used to generate the original BOOT.BIN file. The Zedboard boots properly, but there is no video output (the HDMI monitor shows no display at all). Here are the two boot logs, one with the original project working properly and the second one where the video output fails.
boot log good (http://pastebin.com/2mR4va5r)
boot log hdmi problem (http://pastebin.com/kebAVeir)
The mayor difference between the 2 boots is this one:
GOOD ONE (lines 292 to 303):

HDMI PROBLEM (lines 309 to 319)

As you can see one is using YCbCr color space and the other one is using RGB, why do you think this is happening?
Hope you can help me on this one!
Thanks!
Nicolas
