So the errors you have are:

  1. undefined reference to `__OPENAMP_region_start__'
  2. undefined reference to `__OPENAMP_region_end__'

They sound like Linker symbols, which would be defined in the Linker script.

 

Give details of how you created this project; where did you obtain the OpenAmp code?
