Other Parts Discussed in Thread: HALCOGEN
Hello,
Currently working with a TMS 470 evaluation kit which has an on board XDS100V2 emulator probe.
I am able to create project shells with HALCOGEN but I am unable load the FlashEABI_Flash example code, here is my process:
First importing the project from the .pjt file:
in this case I trying to use the 'FlashEABI_Flash.pjt:
Following the instructions from the 'TMS470/570 Platform F035 Flash API Reference
Guide v1.09' use the following configuration settings (I have tried all three libraries):
When I try to debug the code I get the following list of errors:
coming from my boot.asm file:

My hunch is a simple configuration change or a compiler issue (tried the most current version as well as 5.1.6 as referenced in the API document).
As I am sure you can tell - I am quite the rookie in the embedded system world! I will keep plugging away and look forward to any feed back!
Best,
Chris
