AM335x ISDK EtherCAT full application

Other Parts Discussed in Thread: SYSBIOS

Hello,

I'm trying to run full application of EtherCAT in AM335x ISDKv1.1.0.4. I build and run the out file below. I see "SSC Box 1 (TIESC-001)" in TwinCAT. But I can't control LEDs on ICE2 by TwinCAT v2.11.
C:\ti\am335x_sysbios_ind_sdk_1.1.0.4\sdk\protocols\ethercat_slave\ecat_appl\Debug\ecat_appl.out

I can run demo application which controls LEDs. It's fine. I see "SSC Box 1 (TIESC-001)" in TwinCAT.
C:\ti\am335x_sysbios_ind_sdk_1.1.0.4\sdk\examples\ethercat_slave\Debug\ethercat.out

There is a description of "TI Box 1 (ti-esc)" in TwinCAT for running full application. Is this the reason why full application is not working?
http://processors.wiki.ti.com/index.php/Configuring_TwinCAT_For_AM335x

I have copied TI_ESC.xml and TiEtherCATLib.xml to EtherCAT folder. Please give me advice.

Regards,
Kazu

    Kazu,

    Are you running Free Run mode? Is the slave in OP state? Click Box 1 (ti-esc), and see Online tab.

    Once slave is in OP state, go to Box > DO Outputs > LED N to turn it on or off.

    Thanks,

    Hello Srikant,

    Thank you for your reply. I select Device1 (EtherCAT) and goto Actions > Select Set/Reset TwinCAT to Config Mode. Then I'm asked about Active Free Run, I select Yes. This put "SSC Box 1 (TIESC-001)" into OP state when I run demo application. But not when I run full application. It remains INIT state. I can't change state even though I click Op in State Machine. Is my out file of full application incorrect?

    Regards,
