AM62x EVM set up as PTP4l follower connected to another device setup as grandmaster results in seeing many "received PDELAY_REQ without timestamp" messages if in P2P mode (TI was able to replicate) and "DELAY_REQ without timestamp messages" if in E2E mode (customer reported). This shows up for SDK 11.0 and SDK 11.1

Could be related to and issue on errata i2401 workaround where NOT every ptp4l message is being timestamped?

--> AM62Px doesn't show the "without timestamp" messages at least for the length of time that I ran for in the logs

--> AM62x shows "PDELAY_REQ without timestamp" message
