What is Elelabs EZSP Firmware Update Utility?

The Elelabs EZSP Firmware Update Utility is a basic Python3 script to update the firmware inside a range of Elelabs Zigbee products to a newer version.

Supported products:

• Elelabs Zigbee Raspberry Pi Shield ELR023 (EFR32MG13P Silicon Labs MCU inside)
• Elelabs Zigbee USB Adapter ELU013 (EFR32MG13P Silicon Labs MCU inside)
• Elelabs Zigbee Raspberry Pi Shield ELR022 (EFR32MG1B Silicon Labs MCU inside)
• Elelabs Zigbee USB Adapter ELU012 (EFR32MG1B Silicon Labs MCU inside)
• Elelabs Zigbee Raspberry Pi Shield EZBPIS (EM357 Silicon Labs MCU inside) TODO
• Elelabs Zigbee USB Adapter EZBUSBA (EM357 Silicon Labs MCU inside) TODO

The utility as well supports other generic EZSP adapters from other vendors. But the update firmwares are not provided and there is no warranty that it will work.

Getting Started

• Download or clone the repository
• Get your Python3 ready
• Install the required packages using the pip utility

pip3 install -r requirements.txt

• Connect your Elelabs Zigbee EZSP Product to your PC or Raspberry Pi

• Find out the Serial port number of the Elelabs Zigbee EZSP Product

  • For Raspberry Pi Shield it is probably /dev/ttyAMA0
  • For USB Adapter on a Linux PC or Raspberry Pi it is probably /dev/ttyUSB0 (the number 0 may be different)
  • For USB Adapter on a Windows PC it is probably COM1 (the number 1 may be different)

• Launch the probe command to check if everything is working as expected

python3 Elelabs_EzspFwUtility.py probe -p /dev/ttyUSB0

How to

ele_update – Switch Elelabs Zigbee Products between EZSP v6 and v8

only for Elelabs products

The ele_update is the easiest way of updating Elelabs Zigbee EZSP Products to a newer version of the EZSP protocol. The firmware update files are stored in the same repository and are automatically selected by the utility itself.

Switch to EZSP v8

python3 Elelabs_EzspFwUtility.py ele_update -v v8 -p /dev/ttyS6

Switch to EZSP v6

python3 Elelabs_EzspFwUtility.py ele_update -v v6 -p /dev/ttyS6

probe – Check the version of the connected generic EZSP product

for any EZSP product

The probe is used to detect the version of the connected EZSP product or to detect if the product is in bootloader mode.

python3 Elelabs_EzspFwUtility.py probe -p /dev/ttyS6

Product in normal EZSP mode

Product in bootloader mode

restart – Restart the connected generic EZSP product in Normal EZSP mode or in Bootloader mode

for any EZSP product

The restart is used to probe the connected EZSP product and restart it in normal or in bootloader mode. The normal mode is regular EZSP operation. The bootloader mode is used only for the firmware update.

Switch from Normal mode to Bootloader mode

python3 Elelabs_EzspFwUtility.py restart -m btl -p /dev/ttyS6

Switch from Bootloader mode to Normal mode

python3 Elelabs_EzspFwUtility.py restart -m nrml -p /dev/ttyS6

flash – Perform Firmware Update on the generic EZSP product

for any EZSP product

The flash is used to restart the connected EZSP product in bootloader mode and perform Firmware Update using XMODEM protocol. You need to provide an actual file for this utility. !!BE CAREFULL!! as this might damage or 'brick' your product.

python3 Elelabs_EzspFwUtility.py flash -f YOUR_NEW_EZSP_FIRMWARE_FILE.gbl -p /dev/ttyS6

Recover

If for some reason the update or flash utility failed and your product is no longer responding.

1. probe the EZSP adapter as described. Most probably it is now in the Bootloader mode
2. try to restart the EZSP adapter in nrml mode. If success -> your product is working now
3. try to flash the EZSP adapter with the firmware file. If the product is in btl mode it will probably work
4. contact Elelabs: info at elelabs.com
