How to implement gPTP on ls1028ardb

[HingWong]

I want to implement gPTP function on LS1028ARDB, I use flexbuild_lsdk_2108 to generate the image file, which does not have linuxptp, how should I install linuxptp on LS1028ARDB? Or, is there any other way to implement gPTP functionality?

If linuxptp has not been installed in ubuntu, install it on the target board as the following. And make sure stop and disable the default ptp4l service which may be using wrong configuration.
# apt update
# apt install linuxptp
# systemctl stop ptp4l.service
# systemctl disable ptp4l.service

Thank you for your reply! Does LS1028RDB need to connect to the Internet? It seems that apt install linuxptp is not available in tinydistro.

LS1028RDB needs to connect to the Internet.

Please use Ubuntu main rootfs.
