CCS/TMS320F28035: Errors running c2000ware sample codes.

Part Number: TMS320F28035
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hello,

I'm trying to create a pwm with a duty cycle controlled by the adc output. After struggling with this, I decided to check the c2000ware examples. Specifically, the Adcsoc and AdcTempSensor. While running either of these examples, i get the following set of errors. Until i can get these examples working, I am a bit stuck on how to get my own code working. I will also include the sample files. Thanks for any help I can get.
