Firmware Upgrade Operations for eth-52P/P7 Device

The eth-52P/P7 device includes two application firmwares: the ​​web application firmware​​ (fs.bin) and the ​​ESP SoC application firmware​​ (ota.bin), as well as a ​​full firmware​​ (full.bin) that combines both.

​​1. Full.bin Firmware​​

•​​Upgrade Method​​: Currently, the full.bin firmware can only be upgraded via the flash_download_tool Downloadtool on a local computer.

•​​Note​​: Upgrading full.bin will erase the entire flash memory, restoring all device configurations to factory defaults. This method is generally recommended ​​only when the device malfunctions​​ and cannot operate normally.

​​2. Web-Based Online OTA Upgrade (for ota.bin)​​

•​​Scope​​: This method supports upgrading only the ​​ota.bin firmware​​ (ESP SoC application firmware).

•​​Process​​: The web interface displays all released firmware versions, allowing users to select the latest or a specific version for upgrade.

•​​Recommendation​​: This is the preferred method for most users, as the web application firmware (fs.bin) is stable and rarely modified after release.

​​3. Web-Based Local Upgrade (for ota.bin and fs.bin)​​

•​​Scope​​: This method supports upgrading both ​​ota.bin​​ (ESP SoC application firmware) and ​​fs.bin​​ (web application firmware).

•​​Process​​: Users can download desired firmware versions (e.g., from Releases) to their local computer and perform the upgrade via the web interface.

•​​Advantage​​: Local upgrades are faster than online OTA upgrades.

•​​Recommendation​​: This method is recommended when the web-based online OTA service is unavailable (e.g., due to network issues or server unavailability).

​​4. Summary​​:

•Use flash_download_toolfor full.bin upgrades (factory reset required, last resort).

•Use web-based online OTA for ota.bin upgrades (recommended for routine updates).

•Use web-based local upgrades for ota.bin/fs.bin when online services are inaccessible (faster alternative).

​​5. Firmware Upgrade Operation Guide​​:

5.​​1 Full.bin Upgrade ​​

The latest full.bin firmware can be downloaded from the esp32-ETH-52 directory within the inswift-eth GitHub repository, or from released firmware tags.
