Environment:
- IDE: Atmel Studio 7.0
- Visual Micro: extension for Atmel Studio 7
- Platform: MegaCoreX v1.1.5 (ATmega4809)
- Board ID: 4809 (runtime.vm.boardinfo.id=MegaCoreX_4809)
- OS: Windows 11 ARM running in Parallels virtual machine on macOS
- Build configuration: Release

Problem:

Custom recipe.hooks.* entries defined in the project-level board.txt are completely ignored during the build. They do not appear in the resolved Board Properties and are never executed.

Hardware property overrides in the same board.txt file (bootloader fuses, build.f_cpu, etc.) work correctly - only recipe.hooks.* entries are affected.

This setup worked without any issues on a previous installation (Windows 11 x86 on Parallels). The current environment is a fresh install on Windows 11 ARM on Parallels. Drive G: is a network-mapped drive (mapped from macOS host), same as on the previous installation where it worked fine.

I need to run a post-build step that calls an external tool on the output .hex file.

Project board.txt (simplified):

nona4809.build.f_cpu=20000000L
nona4809.build.text_section_start=.text=0x0800
recipe.hooks.postbuild.preupload.pattern.windows=cmd.exe /c "G:\MyProject\PostBuild.bat" "{build.mcu}" "{build.path}\{build.project_name}.hex"

The nona4809.* lines above are applied correctly. The recipe.hooks.* line is silently ignored.

What I've tried:

- recipe.hooks.postbuild.preupload.pattern.windows=...
- recipe.hooks.savehex.presavehex.3.pattern.windows=...
- recipe.hooks.savehex.postsavehex.1.pattern.windows=...
- 4809.recipe.hooks.savehex.presavehex.3.pattern.windows=...
- nona4809.recipe.hooks.savehex.presavehex.3.pattern.windows=...
- MSBuild AfterBuild target in .cppproj (gets overwritten when Visual Micro regenerates the project file)

None of the above appeared in Board Properties or executed.

What DOES work:

Hooks defined in platform.txt (MegaCoreX) execute correctly. presavehex.1 and presavehex.2 from platform.txt appear in Board Properties and run during the build. Only hooks from project-level board.txt are ignored.

Current workaround:

Patching platform.txt directly to add a presavehex.3 hook. This works but affects all MegaCoreX projects globally and will be lost on platform updates.

Questions:

1. Is this expected behavior - that recipe.hooks.* in project board.txt are not supported in Visual Micro for Atmel Studio 7?
2. Is there a recommended way to add per-project post-build steps that persist?
3. Could running Windows 11 ARM under Parallels be a factor?

Visual Micro is updated to the latest release. Build output with "vMicro > Compiler > Show Build Properties" enabled is attached as a .txt file.

Thank you.

In the log the hooks were prefixed with the board id, which means they wont be picked up.  If the hook is shortened to just recipe.hooks.postbuild.preupload.pattern then it should work as expected.

Does that solve the issue?
