描述

In the 2020.2 and 2021.1 releases, the Device Tree fails to build when ILA is added to a Versal AXI Stream Interface IP. The below errors are returned:

解决方案

This is a known issue in the 2020.2 and 2021.1 release of the Device Tree Generator (DTG) for Versal devices.

To fix this issue, you will need to apply the attached patch.

Note: In order to apply this patch on top of the 2020.2 release, you will need to first apply the patches from (Xilinx Answer 76440) in sequence.

Root Cause:

The Device Tree Generator does not support Versal ILA with the AXI4 Stream Interface.

PetaLinux:

The patch should be applied to <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/device-tree_%.bbappend recipes

Note: For information on how to apply a patch to recipes in PetaLinux, please refer to (UG1144) or https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842475/PetaLinux+Yocto+Tips

1) Copy the attached patch from the Attachments section to the device-tree directory as shown below.

If these directory and recipes do not exist then manually create <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/files/

$ mkdir -p <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/files
$ cp 0001-common_proc-Add-support-for-Versal-ILA-with-AXI4-Str.patch <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/files

2) Modify the device-tree.bbappend file with the below content using a text editor:

$ vim <plnx-proj-root>/project-spec/meta-user/recipes-bsp/device-tree/device-tree.bbappend
  
# device-tree.bbappend content
# Note: system-user.dtsi is autogenerated from petalinux tool.
SRC_URI += " \
    file://system-user.dtsi \
    file://0001-common_proc-Add-support-for-Versal-ILA-with-AXI4-Str.patch \
"
 
FILESEXTRAPATHS_prepend := "${THISDIR}/files:

3) Clean the device-tree sstate cache and rebuild the device-tree recipes:

$ petalinux-build -c device-tree -x cleansstate
$ petalinux-build -c device-tree

Yocto:

The patch should be applied to <yocto-proj-root>/sources/meta-xilinx-tools/recipes-bsp/device-tree/device-tree.bbappend recipes

1) Copy the attached patch from the Attachments section to the device-tree directory as shown below.

If these directory and recipes do not exist then manually create <yocto-proj-root>/sources/meta-xilinx-tools/recipes-bsp/device-tree/files

$ mkdir -p <yocto-proj-root>/sources/meta-xilinx-tools/recipes-bsp/device-tree/files
$ cp 0001-common_proc-Add-support-for-Versal-ILA-with-AXI4-Str.patch <yocto-proj-root>/sources/meta-xilinx-tools/recipes-bsp/device-tree/files

2) Modify the device-tree.bbappend file with the below content using a text editor:

$ vim <yocto-proj-root>/sources/meta-xilinx-tools/recipes-bsp/device-tree/device-tree.bbappend
  
# device-tree.bbappend content
SRC_URI_append = " \
    file://0001-common_proc-Add-support-for-Versal-ILA-with-AXI4-Str.patch \
"
 
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

3) Clean the device-tree sstate cache and rebuild the device-tree recipes:

$ bitbake device-tree -c cleansstate
$ bitbake device-tree
