Hi!
I follow the use guide (HOWTO_Install_IAR_Eclipse_plugin_into_S32_Design_Studio_for_ARM.pdf) as attached file to install the IAR plug on s32 design studio.
1. Install IAR Plugin manager

When asking to enter the path to the IAR Embedded Workbench SDI, those selected by default appear.

I select the path C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.4, and give it "apply" and "ok".

it does not save the changes, I open the preference window again and it keeps the default.

It's a problem because without this, I can't debug with the IAR.
