AM2434: LRW Access to Non-Interleaved Input and Output Process Data

Sergei Pilipenko

Part Number: AM2434

Tool/software:

Hello,

There are a known issue with "LRW access to non interleaved input and output process data of multiple slaves does not work" - described in the Errata attached.

a month ago we received a fix for this issue from the TI support team (the attached ZIP file), it looks like it solved the issue but created anew ones.

Now with Beckhoff controller CX502D only one slave is working, when we connect a second slave the slaves state jumps between INIT and PREOP and doesn't get to OP.

When we revert the suggested fix, we can connect multiple slaves to Beckhoff controller.

thanks,

Sergei.

Is it possible to share the wireshark logs for the failing scenario along with the error message (if any) ?

We have shared an updated firmware with few fixes. Do test it and let us know if that resolves the current error scenario.

Regards,
Aaron

Hello,

The updated firmware solves the error scenario.
We are continue to testing the new FW, but it already looks much better than previous one.

thanks,
Sergei
