FIRMWARE UPGRADE REQUIREMENTS AND FLASHING SOFTWARE LINKS

New firmware for all popular CC2652 adapters is released relatively regularly by the community, and each release is based on latest upstream SDK from Texas Instruments and contains loads of bug-fixes.

Dongle firmware upgrade prerequisites key points are:

• Use a USB extension cable (due to USB plug on the dongle being very short it might not be fully inserted physically on some chassis/enclosures unless use USB extension cable with longer plug).
• Install official CP210x USB to UART Bridge VCP Drivers from Silicon Labs if using Windows or Mac → https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
• Get either the correct firmware image with name “CC1352P2_CC2652P_launchpad_.zip*” for Zigbee Coordinator → https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator/Z-Stack_3.x.0/bin or alternatively get the correct firmware image with name “CC1352P2_CC2652P_launchpad_.zip*” for Zigbee Router → https://github.com/Koenkk/Z-Stack-firmware/tree/master/router/Z-Stack_3.x.0/bin

Adapters based on CC1352 or CC2652 chips can be flashed by putting them in the bootloader. After you have done this one of the following tools can be used to flash it. See your adapter manual on how to enable bootloader (boot mode) manually or use software that support automatic BSL mode for it.

Upgrade firmware with one of these (ZigStar GW Multi tool and cc2538-bsl support auto BSL):

• ZigStar GW Multi Tool (multi platform portable GUI tool).
• cc2538-bsl (open source multi-platform Python-based command line tool with auto-BSL trigger).
• llama-bsl (open sou multi-platform Python-based CLI tool, a fork of cc2538-bsl).
• FLASH PROGRAMMER 2 by Texas Instrumens (Windows installer only, with auto-BSL trigger).
