Hi Michael,

You can also try to move your TF-M project close to the root (C:\) folder.

It works for me in “C:\projects\trusted-firmware-m” in Windows build.

Hope that helps,

Anton

Hi Michael,

I am not an expert on make but it looks like it's hitting some corner case on the size of the file being processed? I'd suggest to use as a workaround ninja, if possible, instead of make, and use -GNinja in the CMake config options when configuring the project.

Thanks, Antonio

Subject: [TF-M] Windows 10 error file name or extension too long

Hi all

I am new to TF-M and want to know if there is a public forum to post questions or search for answers? I am getting this error under Windows 10 when making clean:

make (e=206): The filename or extension is too long

Thank you

Michael
