Flashing the CC2531 Z-stack firmware

It’s assumed you already have an Operating System running on the Raspberry Pi and know your way around the command line.
Connecting the dongle to the Pi
With the Raspberry Pi turned off, plug the Dongle into an available USB port. Connect the Zigbee USB stick to the Raspberry PI GPIO:
|ZigBee USB stick pin||Raspberry Pi GPIO pin|
Once everything is connected up, you can power on the Raspberry Pi. Hopefully you won’t see any magic smoke escaping.
Flashing the firmware
The next step is to flash the Z-stack firmware to the dongle.
Sudo to root:
Install some dependencies:
apt-get install wiringpi git unzip
Change into the opt directory:
Clone the repo:
git clone https://github.com/jmichault/flash_cc2531.git
Change into the new directory:
Check the dongle is properly connected, by running the command below. It should return the ID as b524. If there is an error, check the connections!
In my case, I got ID 000. Problem was not caused by the connections, but by an outdated Raspbian and wiringpi library. Updating/upgrading solved it.
Download the latest firmware and unzip it:
wget https://github.com/Koenkk/Z-Stack-firmware/raw/master/coordinator/Z-Stack_Home_1.2/bin/default/CC2531_DEFAULT_20190608.zip unzip CC2531_DEFAULT_20190608.zip
Erase and flash the firmware. It should take around 3 minutes:
./cc_erase ./cc_write CC2531ZNP-Prod.hex
Once you see “Flash Ok” you’ve finished flashing the firmware and can start using the dongle.
