I checked and found HDMI Driver having some issue in kernel version 5.4.51(trunk), which got resolved in the later release.
Now, i migrated to the latest one and having working HDMI.
Thank You @Werner for your support !
Sorry for bothering you guys again -
I have one more query, related to root file system, I am using ubuntu bionic (18.04) root file system.
Installed quagga version 1.2.4_1, It has some bug in this release later they fix this bug and release a latest version i.e 1.2.4_8.
Here my question is, how i update this package to the latest one in Ubuntu Bionic root file system.
Older version of quagga is installed during image creation by putting package name in lib.config file under userpatch dir.
Please guide me or point me to the docs, how i update this during image build.
I appreciate you support here
