[Petalinux zybo z7 HDMI no output]

I want to boot petalinux with linaro on my Zybo Z7-10 board, First I tested with the tutorial : https://github.com/Digilent/Petalinux-Zybo-Z7-10 . I got the hdmi output but with wrong colors and graphics rendering. I found a post with the same issue, then I changed the block design, I did the following steps,

Made a block diagram in vivado 2017.4 as given in 1.png

Inside the hdmi block is in 2.png

Both images attached herewith.

I got this HDMI project from here (https://wiki.york.ac.uk/display/RTS/Zybo+Z7+HDMI+Output with https://github.com/RTSYork/zybo-z7-hdmi)

 

I generated the bitstream and exported the hardware (with include bitstream selected) to get the .hdf file, I tested this design I am getting the HDMI output ok on my HDMI TV

 

Now I goto petalinux 2017.4 and did initial settings,

 

source /opt/pkg/petalinux/settings.sh

echo $PETALINUX

petalinux-util --webtalk off

 

Created new project, and add my hardware to it,

petalinux-create --type project --template zynq --name zyboz7

cd zyboz7/

petalinux-config --get-hw-description=/home/aashish/peta/LINUX/linux/linux.sdk

 

the changes I made are,

Linux Components Selection --->u-boot (ext-local-src) --->

  ( ) u-boot-plnx                      

  ( ) remote                             

  (X) ext-local-src 

 

External u-boot local source settings --->(/home/aashish/peta/zyboz7/components/u-boot-digilent) EXternal u-boot local source path

 

DTG Settings --->Kernel Bootargs --->(console=ttyPS0,115200 earlyprintk root=/dev/mmcblk0p2 rw rootwait) Auto generated bootargs (NO EDIT!)

 

Image Packaging Configuration --->

 ( ) INITRAMFS                        

 ( ) INITRD                           

  ( ) JFFS2                            

  ( ) NFS                              

 (X) SD card                          

 ( ) other

 

Now I build the project successfully,  

petalinux-build

 

Generated the boot files,

petalinux-package --boot --force --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/design_1_wrapper.bit --u-boot

 

Now I Format an 16GB SD card with two partitions: The first 600 MB and be FAT32 formatted. The second partition has remaining space and formatted as ext4.

 

Copied images/linux/BOOT.BIN and images/linux/image.ub to the first partition of SD card. and  linaro to the second partition of SD card,

 

lsblk

cd /media/aashish

ls

cd Downloads/

ls

sudo tar -xzvf linaro-precise-ubuntu-desktop-20120923-436.tar.gz -C /media/aashish/1f3b4346-f0a4-444f-9e1b-86d3c6ca226e

mkdir -p /tmp/linaro

sudo cp linaro-precise-ubuntu-desktop-20120923-436.tar.gz /tmp/linaro/fs.tar.gz

cd /tmp/linaro

sudo tar zxf fs.tar.gz

cd binary/boot/filesystem.dir

mkdir -p /tmp/sd_ext4

sudo mount /dev/sdb2 /tmp/sd_ext4

cd /tmp/linaro/binary/boot/filesystem.dir

sudo rsync –a ./ /tmp/sd_ext4

sudo rsync -a ./ /tmp/sd_ext4

sudo umount /tmp/sd_ext4

 

But after spending whole night at the end I got no output on my HDMI tv. I also noticed that my system-user.dtsi is empty after building my petalinux

Please help me to solve this problem.
