mkdir %CSS_WORKSPACE%

C:\ti\ccsv6\eclipse\eclipsec -noSplash -data %CSS_WORKSPACE% -application com.ti.ccstudio.apps.projectImport -ccs.location %DIR%\ > %LOG%
if %errorlevel% neq 0 exit /b %errorlevel%

C:\ti\ccsv6\eclipse\eclipsec -noSplash -data %CSS_WORKSPACE% -application com.ti.ccstudio.apps.projectBuild -ccs.projects %PROJECT% -ccs.configuration %TARGET% -ccs.autoOpen -ccs.buildType incremental >> %LOG%
