PetaLinux 2014.2 - Device Tree Generator Does Not Generate Device Nodes for All IP

Description

When generating the device tree for my system with PetaLinux 2014.2, some IP are missing from the generated device tree DTS file. 

Is this expected behavior?

Solution

Yes, this is expected behavior.  

Currently, the PetaLinux 2014.2 device tree generator cannot generate device tree nodes for the following IP blocks:

  • AXI VDMA
  • AXI CDMA
  • AXI Timebase WDT
  • Mailbox
  • AXI-PLB Bridge
  • AXI-to-AXI Bridge
  • AXI EPC

For future support, please reference the Xilinx Git repository located here: https://github.com/Xilinx/device-tree-xlnx

To use a device tree generator from the Xilinx Git repository, download the Git archive and then use the --searchpath option with the petalinux-config command to use it during project initialization.
