Hi akspatel23,
basically, it should be possible to build the Embedded Wizard examples using version 8.22.1 also.
However, as already mentioned the IAR project file is prepared for 9.10.1 and above and I assume, that IAR workbench is not able to convert project files created with newer IAR versions.
Therefore, I think to build the Embedded Wizard examples with IAR 8.22.1, a new IAR project has to be created. Maybe, the makefile contained in the Build Environment can be helpful.
Regards,
Martin
