Part Number: TMDSECATCNCD379D
Tool/software: Code Composer Studio
The customer have an EtherCAT ring with 2 boards connected like this:
TwinCAT NIC -> (IN port) Ecat board 1 (OUT port) -> (IN port) TMDSECATCNCD379D
The problem with TMDSECATCNCD379D is TwinCAT shows the error with its state: ERR SAFEOP INIT_ERR
I also have a TI AM335X ICE Rev 2.1A board and it doesn’t have this problem.
The state of TMDSECATCNCD379D was supposed to be OP.
He uses TI Code Composer Studio V9.0.1 for TMDSECATCNCD379D.
TMDSECATCNCD379D uses SPI mode to talk to ESC(ET1100).
Maybe he have some incorrect settings either on TwinCAT or TMDSECATCNCD379D?
AM335X ICE uses uP interface. Maybe SPI needs some different settings?
Is it a known problem? Did you have a fix for it?
Hi, I asked Gui Kang this question. The 2 EtherCAT boards were actually in a daisy chain topology, not ring. I used the TI provided SSC for the TMDSECATCNCD379D eval board with SPI interface to the ET1100.
Update: If I put an AM335X ICE board as the first node, the TMDSECATCNCD379D status was correct(OP). It seems to be a problem with the previous Ecat board on the first location.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to user6065946:
If the 379D board is the only ECAT slave in the network, does it go to OP?
We've tested multiple 379D ECAT slaves together we no issue going to OP. Make sure you are following all steps in the user guides.

Thanks for your reply. If the 379D board is the only ECAT slave, it goes to OP.
It seems to be a problem with my old ECAT board. Please mark it as solved.
