XU5 reference design and v1.8.2

[gtortone]

Hi, I'm evaluating Enclustra XU5 module on PE1-300 carrier board. To do this activity I'm using these software releases:

• Vivado/SDK 2018.3
• Mercury XU5 Reference Design for Mercury PE1 V6.2 (from https://download.enclustra.com/)
• Xilinx Linux device tree generator for the Xilinx SDK (from https://github.com/Xilinx/device-tree-xlnx)

The problem is that latest Mercury XU5 reference design (6.2) are based on Vivado 2019.1 as reported in MercuryXU5_bd_PE1.tcl and when I use Xilinx Linux device tree generator on hdf file it produces a devicetree.dtb not compatible with Linux kernel 4.14.0 (your v1.8.2 tag) and at boot Linux hangs...

Can you report this problem to people that are in charge of Mercury XU5 reference design ?

A simple solution could be to align Mercury XU5 reference design on 2018.3...

Thanks and sorry for this off-topic request.

Hi Gennaro

The XU5 reference design can be opened and generated with Vivado 2018.3 without any modifications (there might be a warning when you regenerate the project, but you can ignore it). We never used the Xilinx device tree generator, therefore, I don't know if the generated devicetree works out of the box. Probably some modifications are needed (e.g. disable 1.8V support for SD card controller).
