[etherlab-dev] "Failed to read number of assigned PDOs for SM2" error occurs.

[권태영]

Hello.

 

I am testing the EtherLab with the MicroChip EVB-LAN9252-ADD-ON board.

The EVB-LAN9252-ADD-ON board is connected to ODROID-C1 and is used as an
EtherCAT slave as SOES(SPI communication).

Kernel version is using version 3.10.

 

I tested the ported SOES with OMRON-NJ501-1500 PLC and Sysmac Studio.

I have compiled EtherLab to do the same EtherCAT Master operation.(etherlab-
bundle-2.1)

 

I tried to control it with the ethercat command.

However, the following error message appears.

 

===================================================================

EtherCAT WARNING 0-0: Received mailbox protocol 0x08 as response.

EtherCAT ERROR 0-0: Failed to read number of assigned PDOs for SM2.

EtherCAT WARNING 0-0: Received mailbox protocol 0x08 as response.

EtherCAT ERROR 0-0: Failed to read number of assigned PDOs for SM3.

EtherCAT 0: Bus scanning completed in 90 ms.

EtherCAT 0: Using slave 0 as DC reference clock.

EtherCAT 0: Slave states on main device: PREOP.

EtherCAT ERROR 0-0: Received mailbox protocol 0x08 as response.

===================================================================

 

On the EVB-LAN9252-ADD-ON board, only the Run LED is blinking.(PEROP)

 

How can I tell if I can solve this problem?

Why does this error occur?

I am EtherCAT Newbi.... :(

 

The attached log.txt is all the commands and logs I have run.

The attached kty.xml file is the ESI file currently being used by the
EtherCAT Slave.

The attached 2.jpg is the current status of my board.

 

Regards 

Kwon
