Create/export application for IAR Embedded Workbench

. At the end of the process, you should see messages in the console. For a PSOC™ Control C3 device, one of the messages should read as follows:

The project is an ARM Trustzone secure project. The following need to be enabled in Embedded Workbench IDE.
Project->Options->General Options->32 bit->TrustZone

In most cases, PSOC™ Control C3 applications are set to Trust Zone Secure by default. For more details about TrustZone technology, refer to the Arm® website:

https://www.arm.com/technologies/trustzone-for-cortex-m.



When you open the application in IAR Embedded Workbench, you need to check the TrustZone setting. Open the Options dialog, go to

General Options > 32-bit

and verify that the TrustZone

Mode

is set to "Secure."



Save the application and select

Project > Make

to build it. The Output should display the progress, ending with text similar to this:

The following sections provide details about working with a device with the default out of the box policy versus a device that has been provisioned.



Note:By default, applications created from code examples default to TrustZone "Secure" mode. For details about PSOC™ Control C3 security, refer to Application Note
