DTG nodes are not created in Petalinux 2020.1

[rfried]

Hi,

We have a working HW design with MRMAC and AXI DMA that works on the device. But I have to write the device tree nodes manually,
The DTG is not generating the nodes automatically, although I see in the device tree repository that the support for these IP's is present.

Tested on: VCK5000 and VCK190.

Hi @rfried 

The release note for the DTG mentions only an initial support for the MRMAC IP:

Thus I am not surprised the DTG is not covering all use cases and you have to write manual entries to the device tree. More will probably be added in future version

Yes, I can see initial support in the DTG. The DTG uses the MDD to see what supported peripherals are found in the XSA

You can check your XSA in XSCT using the command below:

• hsi::open_hw_design test.xsa
• hsi::get_cells *mrmac*

Hi Stephen,
hsi::get_cells doen't list the mrmac or the DMA attached to it.
This is probably the root cause of the problem.
The HW is working with the exported XSA, so I don't understand why it's not shown.
Do you know what could be the reason ?
