CC1350: coprocessor crashes (RTOS ASSERT) taking collector app with it

Marijn Achterkamp
Expert 1460 points
Part Number: CC1350
Other Parts Discussed in Thread: SIMPLELINK-CC13X0-SDK

We have a setup using the TI 15.4 stack with the coprocessor on a CC1350 and the collector app on a BBB acting as gateway.

We have some 20 sensor/actuators in the network and the coprocessor now often crashes when sending messages to all devices

The coprocessor reaches the assert handler and resets. After rebooting it sends the message:

503196.377: Reset Indication: reason: 4 (rtos-assert) version: 3/1/2/3/2
503196.377: reset-indication msg(57800a) nbytes=11 len=6 [ 0xfe 0x06 0x41 0x80 0x04 0x03 0x01 0x02]

While the coprocessor resets and is up and running again after the crash, the collector app (also default TI 15.4 stack) cannot seem to handle this and does not respond anymore after the coprocessor reset.

Of course we want to find the cause of the reet issue on the coprocessor but also I think the collector app should be able to cope with the reset.
any ideas on this issue?

    Although there was no response to my message, it seems from the changelog in SDK3.2 that the issue is fixed (TI154STACK-2859).

    However I cannot find the Linux SDK anywhere. The latest version still shows 2.09 from march 28 2019.

    Where Can we download the latest version of the linux SDK with this fix applied?

    best,

    Hi Marjin,

    I apologize that this thread has been left unaddressed.  I am glad to hear that you discovered the TI 15.4-Stack JIRA ticket which resolves the issue for the SIMPLELINK-CC13X0-SDK v3.20.  The TI-15.4-STACK-GATEWAY-LINUX-SDK v2.10 will be released around the same time that the SIMPLELINK-CC13X2-CC26X2-SDK is updated, planned for sometime in the upcoming week.  You can select the "Alert Me" button on the SDK tool page to be notified of when this occurs.  Meanwhile, the following E2E thread may provide a temporary workaround: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/796810

    Regards,

    Hi Ryan,

    Thanks for your reply and good to hear that the update is coming soon. I subscribed with the Alert me button and hope get it as soon as possible.

    I already applied the item you mentioned however our coprocessor still crashes. It is not quite the same issue as in our case the coprocessor randomly crashes (mostly after handling a lot of traffic) and not every second run.

    Regards,
