I have a Zynq Ultrascale+ MPSoc Development Board(ZCU106). I applied HD-SDI Video Capture and Display Project on it and it works fine. Now I have a custom board and I'm trying to apply HD-SDI Video Capture project on it but I have a DDR3 instead of DDR4 and also my FPGA is different. Therefore I changed FPGA type and DDR configurations and left the other settings same as the reference design when I created the Vivado Project. I generated bitstream, exported hardware and launched SDK.
Xilinx supplies the BSP File for the specific boards and in the reference design they creating petalinux project with BSP:
% cd $TRD_HOME/apu/vcu_petalinux_bsp
% petalinux-create -t project -s xilinx-vcu-trd-zcu106-v2019.1-final.bsp
Then configure the petalinux project with HDF File:
% cd xilinx-vcu-trd-zcu106-v2019.1-final
% petalinux-config --get-hw-description=<Path to prebuilt HDF>

Same tears here. The key is in the device tree hack. Xilinx, of course, don't teach about this, is not their business. And unfortunately there isn't much material to learn, and if there is, too shallow. I found lots, really lots of deceiving posts kind of "build petalinux for a custom board in a few minutes" but isn't that easy. Is not good allowing so many information that is simply not true. Even if it is desirable it was easy. A pleasant lie harms more than a painful truth.
Update: unless success is to get the board to boot and login, even if devices don't work and that 'thing' as an OS is probably useless. That's really easy to achieve.
