Any idea about this error ?

[ToTo]

Fatal error: C3906U: Malformed via file '._build\dfu_ble_svc.__i'.

maybe u forgot semicolon ; somwehere?

I find the problem. It is confusing because it didn't show up before... The problem was in the nomination, the project is under a directory having the special character " ' " in its name.

Thanks for your reaction @Wojtek
