February 27, 20233 yr I'm looking for information about the Ethernet chip on the Orange Pi 5. I need an SBC that has PTP hardware timestamp support (IEEE 1588). According to OrangePi.org, the Orange Pi 5 has the Motorcomm YT8531C, but I have not been able to find documentation that provides the answer about hardware PTP support. Most likely it does not, but I'd like to confirm on an actual device before purchasing one. If you have an Orange Pi 5, you can test this with this command: ls /sys/class/net |xargs -n1 ethtool -T If there is someone that is willing to run this command and post the output, I would appreciate it very much. Note: This is a cross-post from iot.stackexchange. The only response I got there after three days was to check here on Armbian. So here goes.

February 28, 20233 yr Author Fantastic. Thanks @royk! So it looks like the answer is, Yes, the Orange Pi 5 board does have PTP hardware timestamping support. I can only make one post per day, so asking additional questions if you don't mind. What OS and version are you running? I'm guessing armbian, but just want to make sure.
February 28, 20233 yr No problem, I know after a few posts this restriction is gone. Armbian 23.02.2 with the legacy Rockchip kernel.
September 13, 20233 yr I am not sure if things have changed. I bought a new Orange Pi 5 plus, tried both Armbian_23.8.2_Orangepi5-plus_bookworm_legacy_5.10.160.img.xz and Armbian_23.8.2_Orangepi5-plus_jammy_legacy_5.10.160.img.xz from https://mirror-us-phx1.armbian.airframes.io/dl/orangepi5-plus/archive/ but it doesn't show hardware ptp: Capabilities: software-transmit software-receive software-system-clock PTP Hardware Clock: none Hardware Transmit Timestamp Modes: none Hardware Receive Filter Modes: none I am wondering if the Realtek driver included in legacy kernel 5.10.160 has disabled hardware PTP like mentioned in this post: https://serverfault.com/questions/1078760/ptp-support-for-rtl8125b-cg-nic-in-ubuntu-20-04 @royk is this something you could try with the latest Armbian_23.8.x and legacy kernel 5.10.160? If the hardware ptp disappears, we know it is the kernel Realtek driver issue. Otherwise, it may be because Orange Pi changed the underline NIC hardware for the latest production batch.
September 14, 20233 yr @koi It's disabled in the driver https://github.com/armbian/linux-rockchip/blob/rk-5.10-rkr5.1/drivers/net/ethernet/realtek/r8125/Makefile ENABLE_PTP_SUPPORT = n ENABLE_PTP_MASTER_MODE = n
September 15, 20233 yr Thanks for checking! Earlier posts in this thread showed PTP was enabled. Does anybody know why it got disabled now? Is that an oversight during kernel upgrade?
