I finally figure it out why Analog Devices reference design create/generated in Vivado 2014 by script(obviously updated to use new IP's, otherwise it didn't assemble 'Block Design' at all) didn't work. Reason is changes in Xilinx Concat IP, which used in reference design to concatenate interrupt signals from VDMA and I2C IP blocks to Zynq's F2S interrupt bus.
So, now in 2014.1, we got version 2.0 of it and it preserve the order of input signals on the output. Which means we must either change inputs order or change interrupt numbers in DTS.
So, for AD reference design generated in Vivado2014.1 interrupts are:
As of today, 25 May 2014, to create HDL design for ADV7511 from scratch, we have to use Vivado 2013.4, even though Vivado 2014.1 is already available. The reason is some changes in a Xilinx IP's (which I didn't had a chance to figure out yet) prevent HDL design from build/work properly.
First step is to download HDL libraries and projects from AnalogDevices repositories on a github: https://github.com/analogdevicesinc/hdl. You can clone it or download a ZIP. I will download a ZIP and extract 'hdl-master' in my Projects/FPGA/ folder on Windows7 machine.
Second step is to build a few Analog Devices IP required to create ZedBoard HDMI design. Run Xilinx Vivado 2013.4, open a TCL console, change directories and 'source' a .tcl scripts. For example, to build AXI_CLKGEN IP:
After script finish, close created project and build the next. For ZedBoard we have build the next IP's:
After we done with all required IP's, we can build ADV7511 reference design for ZedBoard. In a Tcl Console change directory to ADV7511 and run 'system_project' script.
Script will create block design, run synthesis and implementation, generate bitstream and even export software to SDK(without opening it). This was the case on my system - everything went smoothly. We are done with Vivado and can close it.
We have to create HDL in Vivado 2013.4, but later we can import created project into Vivado 2014.1 and update it to use latest Xilinx IP's.
Let's build a FSBL. We need very typical Zynq first stage boot loader and I covered creation of it before, so now just a short description:
Create new 'Hardware Platform Specification' project (I named it 'ZedBoard-HDMI-HW') and specify HW created in a previous step.
Create Application project (named 'ZedBoard-HDMI-FSBL') using our new 'Hardware Platform' and select to create new BSP for it. Don't forget to use 'Zynq FSBL' template. Build it if this not done automatically.
Next step is to create PetaLinux BSP. This is also very typical PetaLinux BSP, just don't forget to change 'Configuration' to reflect ZedBoard configuration and name it 'ZedBoard-HDMI-petalinux_bsp'.
We are done with Xilinx SDK. You can close it.
Next step is to create PetaLinux project and set 'hardware description'. I will call it 'ZedBoard-HDMI' Petalinux project:
petalinux-create -t project -n ZedBoard-HDMI
petalinux-config --get-hw-description -p ../ZedBoard-HDMI/
rm -r hw-description
Now, as of today, ADV7511 Linux driver not in a mainstream kernel. So, we need to get Kernel from Analog Devices repository with appropriate patches. Current version is 3.14.0. Let's clone it, and checkout 'xcomm_zynq' branch.
git clone https://github.com/analogdevicesinc/linux.git analogdevices-kernel
git checkout xcomm_zynq
Create necessary directories and copy 'xcomm_zynq' branch to our PetaLinux project directory.
cp -a analogdevices-kernel ~/Projects/ZedBoard-HDMI/components/linux-kernel/
Run 'petalinux-config' and change kernel to 'analogdevices-kernel' and system boot device to 'SD card'.
Next we need to configure Linux kernel for PetaLinux and we need to enable all options required by ADV7511. AnalogDevices kernel support special configuration option 'zynq_xcomm_adv7511_defconfig', but we cannot run it with PetaLinux. So, we have to pre-configure kernel separately ('make ARCH=arm zynq_xcomm_adv7511_defconfig') and just copy resulted config into 'ZedBoard-HDMI/subsystems/linux/configs/kernel'. So, I did it and also copied it into PetaLinux Kernel configs directory '/opt/petalinux-v2013.10-final/etc/template/project/template-zynq/subsystems/linux/configs/kernel'. So, I can later reuse it. Also notice that kernel default config file have dot in the front and PetaLinux files don't.
Anyway, here is link to my resulted kernel config file: https://blog.idv-tech.com/wp-content/uploads/2014/05/config_hdmi_3_14.config
We also, have to modify 'devices tree' generated by PetaLinux for our project. AnalogDecices Linux kernel have template for ZedBoard which you can find in 'arch/arm/boot/dts/zynq-zed-adv7511.dts', so we basically have to copy missing devices from AD into our tree.
Link to my resulted DTS file for ZedBoard: https://blog.idv-tech.com/wp-content/uploads/2014/05/adv7511_dts.config.
We are basically done. At this point you my want to modify PetaLinux project, for example, include Qt5 library and test app to check frame buffer device later. I covered this topics in my previous post, so I wont repeat it here.
Build Petalinux project, create BOOT.BIN and copy it together with Linux image file 'image.ub' on SD card:
This is basically it - once you have a framebuffer device you can start using it. So I ran my Qt5 test app and it worked. We obviously don't have any hardware acceleration with this HDL design, but we got basic FB device and HDMI output. Congratulations!
