v0.2.3 Firmware Release for Duo
2nd mass production firmware since 2016/04/20
Updating System Firmware
The OTA method (supported since v0.2.0 )
For devices already online and connected to the cloud, the system firmware can be updated OTA using these commands:
If your device is online, you can attempt to OTA (Over The Air) update these system parts as well with the particle-cli:
Note: You must download system binaries to a local directory on your machine for this to work.
particle flash YOUR_DEVICE_NAME duo-system-part1-v0.2.3.bin
particle flash YOUR_DEVICE_NAME duo-system-part2-v0.2.3.bin
The local DFU-UTIL method
- Put your device in DFU mode (flashing yellow LED)
- open a terminal window, change to the directory where you downloaded the files below, and run these commands:
dfu-util -d 2b04:d058 -a 2 -s 0x140000 -D duo-fac-tinker-v0.2.3.bin
dfu-util -d 2b04:d058 -a 0 -s 0x8020000 -D duo-system-part1-v0.2.3.bin
dfu-util -d 2b04:d058 -a 0 -s 0x8040000:leave -D duo-system-part2-v0.2.3.bin
