AM3359: EtherCAT Slave input data size

Juan Gonzales
Mastermind 37340 points

Part Number: AM3359

My system:

I am using EtherCAT stack (v5.12 from ETG) along with the full slave project (PRU EtherCATsoftware v 1.0.6); per corresponding release notes, these versions are compatible.  Using AM3359 ICE eval kit.

question:

EtherCAT full slave example uses 7 bytes for input process.  I added 64 bytes, total of 71 bytes. I always get 7 bytes regardless. Can you help resolving this issue. I hit some places where the debugger can’t find the source code. I believe its part of the PRU code. Is PRU source code available? Or it’s just binary?

Thank you in advance,

Juan

    Hi Juan, please see attached files from my reply to a similar question in bellow's E2E link (refer Jul 24 2018 post). Mainly you need to change XML, tiescappl.c, and tiescappl.h). In that post I attached the original files and the ones with my changes so you can compare them.

    Just for your background, I tried to get this source code changes automatically with SCC tool, but it didn't work for me, so I decided to do it manually. I hope this helps. 

    thank you,

    Paula
