Configure and build

After creating an application, make a few changes before attempting to build it:

Edit the

Makefile

located in the project folder as follows:

APPNAME=Hello_World 
# Use the same App_Name used to create the project

TOOLCHAIN=IAR

Using your favorite code editor, create a
postbuild.bat
file in the IAR project directory.
Add
SET PATH=%PATH%;"/usr/bin"
at the start of file.
Open a modus-shell terminal from the ModusToolbox™ install directory, navigate to the IAR project directory, and run this command:
```
make build -j8
```

Copy the IAR-related post-build output from the modus-shell terminal. For example:

Paste the post-build output into the

postbuild.bat

file, make the following edits, and save the file:

Change the paths from "build/APP_CYW920829M2EVK-02/Debug/..." to "Debug/Exe/…".
Remove all the semi-colons. We recommend making a line break for each semi-colon.
Delete un-needed commands (e.g., ielfdumparm, rm -rf, and cp).

Example edited file:

PATH=%PATH%;"/usr/bin"

Note:

Make sure to update the paths as needed for your system.

In IAR Embedded Workbench, open the Options dialog, go to
Linker > Output
