	Hi. (AVR, Visual Studio) I observed a strange behaviour in this hook. I have BAT file what takes actual HEX file and merge it with my bootloader. But, the hex file what is merged with bl. is always one version older than actual. I tried disclose it, so in a BAT file I added TIME >c:\temp\time.txt to check what time is when hook starts. I can see a console window on a screen (with my BAT file runnig) first and AFTER that I can see updated HEX on the disk. (my burning software gongs after updating HEX) It seems the hook is started in time, when the HEX file is NOT already fully updated or closed/released. (Maybe is already updated, but not CLOSED in VMicro/Visual Studio ???) Thank you for every info in advance. Tomas

	For manipulating the resulting HEX files the Postbuild hook can be too early (as the build has finished but the hex may still be being moved to the project folder at this point), so the PostSaveHex hook would be a better option: recipe.hooks.savehex.postsavehex.1.use_shell_execute=true recipe.hooks.savehex.postsavehex.1.working_directory={build.project_path}\.. recipe.hooks.savehex.postsavehex.1.create_no_window=false recipe.hooks.savehex.postsavehex.1.pattern=cmd.exe /c mergeAppAndBootload.bat Does this help to resolve the issue?

	Apologies, if you also enable vMicro > Compiler > Always Export Binary this will ensure the hook runs.
