v4.0.4

v4.0.4 is a maintenance release that refreshes the bundled OpenMV firmware to 4.4.3, improves error reporting during camera registration, and updates the RT1060 flash loader. It is based on Qt Creator 10.0.1, and there are no breaking changes.

Highlights

  • Bundled firmware updated to 4.4.3 for all OpenMV Cam boards and the supported Arduino targets.

  • Clearer camera-registration errors now surface explicit dialogs when the form_key registration flow fails instead of failing silently.

  • Updated RT1060 flash loader for the OpenMV RT1060 board.

Other changes and improvements

  • Updated the bundled bootloader/flash-loader binary for the OpenMV RT1060 board (cfa6b2cd1).

Bug fixes

  • When the camera-registration form_key option is set, connecting now surfaces explicit error dialogs (Database Error, network/GET errors, or a non-affirmative server response) instead of silently failing (c3f1f46e6).

Platform and tool support

  • Qt Creator base: 10.0.1.

  • Bundled OpenMV firmware: updated to 4.4.3 for all OpenMV Cam boards (OPENMV2/3/4/4P/PT and RT1060) and the Arduino Nano RP2040 Connect, Nicla Vision, Portenta H7, and Nano 33 BLE Sense (8195c94b0).

Breaking changes

None. Existing projects and workflows continue to work unchanged.
