@ andre.m “restarting the process at the position where it fails…”
There’s no reason that restarting will change anything unless knowing why exceptions are thrown. Therefore I would expect a little bit more details about these exceptions.
"If you have a problem “during or after “InFieldUpdate.FlashAndReset()””, manually update the board.
I assume that if files are loaded properly and that the files are the good one, and no mistake on power line the process is 100% reliable. Manually update when the board is in the middle of nowhere is not an option.
In the previous version (4.2) canupdate was telling if something went wrong and if not the update was started and I only observed one mistake (that we can not still identify see my post on partial IFU that fails).
