Create a Device Tree Binary (DTB) File
Use the createdts command in XSCT tool to
generate a 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_v202X.X -board zcu104-revc -compile-
-platform-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: option to compile the device tree.
The system.dtb file is created in the
<mydevice>/psu_cortexaXX_0/device_tree_domain/bsp
folder.
