CC2520: Z-Stack versions for MSP430F543x + CC2520 + CC2590

Part Number: CC2520
Other Parts Discussed in Thread: CC2590, MSP430F5438A, Z-STACK, , MSP430F5437A, SIMPLELINK-CC13XX-CC26XX-SDK

Hi,

We have been using Z-Stack core 2.6.0.3 for years with MSP430F5437A/MSP430F5438A + CC2520 radio (+ CC2590) configured as coordinators, routers. and end devices in large volumes. The devices are working for the most part, but randomly we see some anomalies that we cannot explain.

I just found the version history / release notes for the Z-Stack core 2.6.3, and there looks to be multiple bug fixes that could explain the majority of the anomalies we see with the use of the older core stack.

However, it seems to be hard to find a complete Z-Stack core version history, and to determine which version would still support the dual chip system (with CC2520), and where from a newer stack could be obtained. I can find the 3.0.2 from TI, but there's no information about the older versions, nor if the 3.x.x could still be applied somehow to the old dual chip systems etc.

In fact, without some sort of merged version history, it is quite hard to figure out which version is which, what HW is supported etc.

Can you tell where this kind of information + suitable stack could be found?

    Hi Ilkka,

    Z-Stack Core 2.6.2 as part of the Z-Stack Mesh 1.0.0 solution on Z-STACK-ARCHIVE is the latest solution to incorporate the MSP430 + CC2520 solution. Z-Stack Home (Z-Stack Core 2.6.3a) and later only have resources for the CC253X MCUs.  The SIMPLELINK-CC13XX-CC26XX-SDK is the latest solution offering Zigbee 3.0 on the CC13X2 / CC26X2 devices.  Zigbee 3.0 cannot be applied to the CC2520 but it would be possible to use the MSP430 as a host for the Z-Stack 3.0 ZNP software for a two-chip solution.  However, this would require updates to the MSP430 gateway firmware which is not provided by TI.  There is a Linux Gateway solution offered for Zigbee 3.0-compatible MCUs which cannot be applied to the CC2520.

    Regards,

    Thank you for this information.

    I fetched the 2.6.2 and read the release notes. However, I'm still a bit confused, what bugs were found and fixed between the 2.6.0.3 and 2.6.2 cores. Are there any stack release version between these two, and is there somewhere some sort of combined version history that would show all the cumulative changes along with the different stack versions?

    As said, the 2.6.3 release notes mentions a few such bug fixes that we expect to suffer in our currently used 2.6.03. If the 2.6.2 is the last one that supports dual chip configuration, does this mean, that the bug fixes listed in 2.6.3 release notes are not implemented in 2.6.2?

    Thanks in advance!

    BR,

    These stack versions have been deprecated for several years and it would not be possible to obtain more information outside of the Release Notes provided.  You could test and verify whether updating to v2.6.2 resolves the issues, if not then you will need to consider a dual-chip solution using a CC253X MCU instead of the CC2520 transceiver.

    Ok, I understand. Changing the hardware is not an option in this case due to the large amount of manufactured devices.

    Thanks for the quick reply, again.
