[PSA] Recommend upgrading Z-Stack 3 Coordinator firmware based on Texas Instruments Z-Stack 4.40.00.44 SDK? about zigpy-znp

[MattWestb]

Best is putting on matrix in the Zigpy Wiki https://github.com/zigpy/zigpy/wiki/Coordinator-Firmware-Updates#instructions-for-znp-radios like i have doing for the EZSP coordinators that is known and on the zigpy and zigpy-znp referring to the wiki for the recommended / working firmware in the Wiki.

Yes, it is very much recommended. I have been reliably able to trigger Z-Stack crashes on older firmwares in about 3-4 hours (by sending requests as fast as possible) that are impossible to reset remotely on both the LAUNCHXL boards and on the ZZH. Slaesh's stick should in theory be able to recover from any lockup with the unreleased reconnect watchdog in the dev branch. New firmware has been running for over 36 hours now without issues.

Hardware requirements

USB-adapters, GPIO-modules, and development-boards running TI's Z-Stack are supported. Reference hardware for this project includes:

• (STABLE) TI LAUNCHXL-CC26X2R1 running Z-Stack 3 firmware (based on version 4.40.00.44). You can flash CC2652R_20210120.hex using TI's UNIFLASH.
• (STABLE) Electrolama zzh CC2652R and Slaesh CC2652R sticks running Z-Stack 3 firmware (based on version 4.40.00.44). You can flash CC2652R_20210120.hex or CC2652RB_20210120.hex respectively using cc2538-bsl.
• (BETA) CC2531 running Z-Stack 3.0.1. You can flash CC2531ZNP-without-SBL.bin to your stick directly with zigpy_znp: python -m zigpy_znp.tools.flash_write -i /path/to/CC2531ZNP-without-SBL.bin /dev/serial/by-id/YOUR-CC2531 if your stick already has a serial bootloader.
• (ALPHA) CC2531 running Z-Stack Home 1.2. You can flash CC2531ZNP-Prod.bin to your stick directly with zigpy_znp: python -m zigpy_znp.tools.flash_write -i /path/to/CC2531ZNP-Prod.bin /dev/serial/by-id/YOUR-CC2531 if your stick already has a serial bootloader.
