Prepare Common Image

Download the AMD common image from the AMD download page, extract it, and place it in the project folder.

Create DTB File

Use the "createdts" command in XSCT tool to generate DTB file. The zocl driver interface requires a device tree node to enable the interrupt connection. Add the -zocl option when using this command. The following code shows the usage of this command with its options.

createdts -hw <full path of XSA file> -zocl -platform-name mydevice -git-branch xlnx_rel_v2021.1 -board zcu104-revc -compile

The system.dtb file is located in <mydevice/psu_cortexaXX_0/device_tree_domain/bsp> folder.

  • -name: Platform name
  • -hw: Hardware XSA file with path
  • -git-branch: device tree branch
  • -board: board name of the device. You can check the board name at /device_tree/data/kernel_dtsi.
  • -zocl: enable the zocl driver support
  • -compile: specify the option to compile the device tree

The following is an example of the zocl device node for your reference.

&amba {
	zyxclmm_drm {
		compatible = "xlnx,zocl";
		status = "okay";
		interrupt-parent = <&axi_intc_0>;
		interrupts = <0  4>, <1  4>, <2  4>, <3  4>,
			     <4  4>, <5  4>, <6  4>, <7  4>,
			     <8  4>, <9  4>, <10 4>, <11 4>,
			     <12 4>, <13 4>, <14 4>, <15 4>,
			     <16 4>, <17 4>, <18 4>, <19 4>,
			     <20 4>, <21 4>, <22 4>, <23 4>,
			     <24 4>, <25 4>, <26 4>, <27 4>,
			     <28 4>, <29 4>, <30 4>, <31 4>;
	};
