How to configure and test the Ethercat Master and slave in nxp imx8mm-lpddr4-evm

[santhana_kumar]

Hi,

I'm using the imx8mm-lpddr4-evk board and following the "NXP Real Time Edge" Yocto build procedure

We are going to test the ethercat protocol for imx8mm board , so we followed the procedures from the "NXP Real Time Software user guide" to setup the master in the EVK board.

Following steps :

1. I've added the MAC address of the slave device to the /etc/ethercat.conf file in the master board. 

   However, the output of the ethercat master command shows that it's stuck at the "Waiting for device(s).." phase. How can I resolve this issue? We are only know the ethercat master seup but don't have the Slave setup.

When I run the command: $ ethercat master

The output I get is:

Master0

  Phase: Waiting for device(s)..

  Active: no

  Slaves: 0

  Ethernet devices:

    Main: 00:1f:7b:1e:30:38 (waiting...)

      Link: DOWN

      Tx frames:   0

      Tx bytes:    0

      Rx frames:   0

      Rx bytes:    0

      Tx errors:   0

      Tx frame rate [1/s]:      0      0      0

      Tx rate [KByte/s]:      0.0    0.0    0.0

      Rx frame rate [1/s]:      0      0      0

      Rx rate [KByte/s]:      0.0    0.0    0.0

    Common:

      Tx frames:   0

      Tx bytes:    0

      Rx frames:   0

      Rx bytes:    0

      Lost frames: 0

      Tx frame rate [1/s]:      0      0      0

      Tx rate [KByte/s]:      0.0    0.0    0.0

      Rx frame rate [1/s]:      0      0      0

      Rx rate [KByte/s]:      0.0    0.0    0.0

      Loss rate [1/s]:          0      0      0

      Frame loss [%]:         0.0    0.0    0.0

  Distributed clocks:

    Reference clock: None

    Application time: 0

Can you please help us to resolve the issue?

Hi @santhana_kumar ,

I hope you're doing well! What version of RTES are you using?

Please review section 7.1.3.3 The 'real-time-edge-servo' stack from the Real Time Edge Software User Guide (https://www.nxp.com/docs/en/user-guide/REALTIMEEDGEUG.pdf ). 

Section 7.1.3.3.3 Xml configuration for real-time-edge-servo goes into great detail regarding master and slave configurations for the xml file using real-time-servo framework.

Let me know if this was of any help.

Best regards,
Hector.

Hi,

Using the Real Time Edge software guide version 2.7.

"real-time-edge-servo" stack needs the hardware component to test the slave from the imx8mm board (Which act as a master)

Can you please tell without using the "real-time-edge-servo" stack & only can we use the normal server & client application to send and receive the ECAT frame between the Ubuntu PC and the imx8mm board?

If the above is possible to send & receive the ECAT frame between the ubuntu PC & imx8mm board, then please share the sample code for this.
