2026.06.04: Firmware update safety mechanism in FOTA Web

We would like to inform you about an upcoming improvement in the FOTA WEB system, designed to enhance the safety and reliability of firmware updates for the devices.


Change description
Change type	Firmware update safety mechanism
Detailed description	We are introducing a new safety mechanism in FOTA WEB that prevents firmware updates from being executed on devices running an outdated bootloader version and in this case the firmware update task won’t be possible. This helps eliminate the risk of device malfunction during update procedures.
Detailed description	Required bootloader version: Minimum required: 65.0E (displayed as 101.14 in FOTA Web). Devices with an older version must first apply a bootloader patch before updating to newer firmware.	Recommended update path: Any firmware → FM65.Ver.03.01.00.Rev.28 → (if required) FM65.Ver.03.01.00.Rev.34_1666 → FM65.Ver.03.01.01.Rev.15 or newer
Change reasons	Certain newer firmware versions, such as FM65.Ver.03.01.01.Rev.15 and later, exceed 1 MB in size. Devices with older bootloader versions may not support these updates safely. The new mechanism ensures that such updates are only performed when the device meets the required bootloader conditions.
Safety mechanism launch date	Jun 15, 2026

Change impact
Risk assessment	The bootloader patch firmware (Rev.34_1666) is an intermediate step and not a full firmware version. Using it as a standalone firmware may lead to limited functionality or unexpected behavior. Starting from version 03.01.00.Rev.28, devices automatically block firmware updates if the bootloader is too old. This protection significantly reduces the risk of bricking.
Suggested implementation plan	Only a limited number of devices require a bootloader update. We recommend avoiding unnecessary bootloader updates. To ensure a smooth and safe firmware update process, please follow the recommended update path sequence provided in the Change description.
