CCS/PROCESSOR-SDK-AM437X: PTPv2

Hello, the usual person to respond to this is out at this time. Please let me see if I can find someone else to help.

Hi,

Thanks, I already checked these topics. Did not help.
My problem is that the board (AM437x) does not respond to the time server (Linux Ubuntu). It turns out that Linux Ubuntu sends PTPV2 packets, and AM437x does not respond to them in any way. But I know for sure that the AM437x accepts these packets.

Hello,

Thank. I am really looking forward to help.

Hello!
I figured out my problem and there are results .....
1. AM437x does not respond to the PTPV2 master because
/ ** PTP State machine. This is a bitmask * /
     / **
      * @brief PTP State machine used internally by driver
      * This is a bitmap
      * Bit 0: Set 1 if First adjustment done
      * Bit 1: Set 1 if delay has been computed
      * Bit 2: Set 1 if sync interval has been computed
      * Bit 3: Set 1 if device is in sync with master
      * if first 3 bits are set then clock adjustment is performed
      * /
     uint8_t stateMachine;

is in state 5, and should be in state 8.

A similar problem is e2e.ti.com/.../751648

2. Some changes are required in the icss_timeSync.c project

Hi Dima,

Good to know you were able to resolve the ptp issue. 

The e2e thread doesn't seem to indicate the state 5/8, would you please post the changes in icss_timeSync.c project as you mentioned above?

Thanks,

Garrett
