Hope to adding the naive RTL8125BG drive to support the HW IEEE1588v2 feature

[Vega Sun]

Hi there,

I'm using the latest version of armbian to run the linuxptp for the ieee1588v2 clock. When I check the timestamp status, the 1Gbps port which is the RTL8122 is no problem, but the 2.5G ports RTL8125BG are only supporting the software timestamp.

However, when I checked the Realtek website, it says that the 8125BG also supports the IEEE1588 clock. I tried to install the driver, but it did not work.

As a beginner in Linux, I probably don't have the knowledge to compile drivers, in this case I sincerely hope that armbian could officially support the hw ptp timestamp in 8125 NIC.

Thank you very much!

I run Armbian Bookworm on a Orange Pi 5+ (with dual Realtek 8125).  As far as I can tell, out-of-the-box, Armbian only includes the mainstream r8169 driver which does not support HW PTP.  You will need to compile the Realtek 8125 driver (version 9.014.01) using the Armbian build system.  Armbian did an outstanding job on their build system making it really simple to generate e.g. new kernel packages (e.g. image, headers, etc.) for any giving Armbian config, but it has a bit of a learning curve... 

On my board, with this driver:

Capabilities:
	hardware-transmit
	software-transmit
	hardware-receive
	software-receive
	software-system-clock
	hardware-raw-clock
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes:
	off
	on

	ptpv2-l4-sync
	ptpv2-l4-delay-req

	ptpv2-delay-req

 

However, I am not knowledgeable enough in PTP to test it properly.   See my experience here
