Hi,
Normally, the IAR should work out-of-the-box and modifying the Makefile should not be necessary.
Please double-check whether the IAR toolchain appears on the Toolchain Selection page of the VisualGDB Embedded Project wizard:
- When creating a new project from scratch
- When trying to import a project
If the toolchain appears while creating a new project and doesn’t appear while importing it, would you be able to send us the .ewp file so that we could check what is going on?
