petalinux 2019.2 Failed to generate meta-plnx-generated layer

[balaji.g]

Hi all,

 I'm trying to figure out why the petalinux-config step fails to generate meta-plnx-generated layer?

after using  petalinux-config --get-hw-description=/home/user/workspace1/balaji/petalinux_project/dtic command i got the following erro:

INFO: Getting hardware description...
[INFO] generating Kconfig for project
INFO: Updating the flash partition size to 0x960000 bytes, based on the bitstream in the HDF

configuration written to /home/user/workspace1/balaji/petalinux_project/dtic/r4dtic/project-spec/configs/config

*** End of the configuration.
*** Execute 'make' to start the build or try 'make help'.

the config log from vi build/config.log command is as follows:

You had no conf/local.conf file. This configuration file has therefore been
created for you with some default values. You may wish to edit it to, for
example, select a different MACHINE (target hardware). See conf/local.conf
for more information as common configuration options are commented.

You had no conf/bblayers.conf file. This configuration file has therefore been
created for you with some default values. To add additional metadata layers
into your configuration please add entries to conf/bblayers.conf.

So how to fix these issue ?

Thanks.
