IAR Project Compatibility Issue[edit]
IAR has recently released a new version of their workbench tool identified as version 5.30. The project files from this version are not backward compatible with older version of the IAR toolset. If you see the following format of error
You are trying to open a project built on the new toolset with an older copy of the IAR Workbench. We have released a set of project files in the older format to support customers with older toolsets.
Option 1:
Locate the file PROJECT NAME.ewp and replace it with the file called "Backup of PROJECT NAME.ewp". The easiest way to accomplish this is to delete the original file and rename the backup file to that of the original file.
As an example using the Basic_MAVRK_MSP430F5438_Template project, you would get rid of "Basic_MAVRK_MSP430F5438_Template.ewp" and rename the file "Backup of Basic_MAVRK_MSP430F5438_Template.ewp".
Option 2:
1. Select OK on the Error Windows.
2. Go to Project->Add Existing Project
3. Select "Backup of PROJECT NAME.ewp"
