Over-The-Air Device Firmware Upgrade (Alpha)#
Wi-SUN Over-The-Air Device Firmware Upgrade (OTA DFU) service is implemented for updating Wi-SUN device's firmware. The component uses the Gecko Bootloader API to perform firmware write, verify, and set to bootload operations.
A Trivial File Transfer Protocol (TFTP) client provides downloader solution to obtain a new Gecko Bootloader File (GBL) file from remote host Over-The-Air, using the Wi-SUN network. The connection to the TFTP remote host can be configured in component configuration file. The entire firmware upgrade session can be managed over CoAP. The service includes notification and status request capabilities.
The Wi-SUN Over-The-Air Device Firmware Upgrade (OTA DFU) service is implemented to facilitate the updating of Wi-SUN device firmware. This component requires the Gecko Bootloader API to execute firmware writing, verification, and boot-load operations.
To obtain a new Gecko Bootloader File (GBL) file from a remote host Over-The-Air, a Trivial File Transfer Protocol (TFTP) client is employed, leveraging the Wi-SUN network. The entire firmware upgrade session is manageable over CoAP, with the service offering remote host connection settings, firmware file selection, notification and status request capabilities. Configuration of the connection to the TFTP remote host can be accomplished even within the component configuration file. To utilize this component, a bootloader must be flashed onto the device. The component relies on functions that reside within the bootloader. To choose the appropriate bootloader, consider factors such as flash location (internal or external) and size. If necessary, apply compression.
