No update possible from v24.5.6

[luminatedhorizons]

Hi,

I am running v24.5.6 (on a "Diamex DX-DTU"). When uploading via firmware updater in the opendtu-webinterface the binary opendtu-generic_esp32.bin e.g. from current v24.8.1, the update is confirmed after this upload. The device restarts. After that restart, still the original v24.5.6 is booted, according to status info in the webinterface.

Are there any hints for getting further debug info, to understand why the update seems not to work?
