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.
