Stand alone code execution

Other Parts Discussed in Thread: MOTORWARE

I have a project that is based off of lab 7a running on the DRV-8301-69M-KIT. It runs fine when it is connected to CCS and even when I stop the debugger and disconnect it from the computer it continues to run fine. However if I cycle the power supply it won't run. I'm thinking that it probably gets stuck at the breakpoint that CCS puts at the start of main() for debugging but I have no idea how to fix this. I'm sure it's probably something simple but I've never used CCS before (or any other TI products for that matter) and I'm not sure how to fix it. I'm using this on an electric vehicle so being tethered to the computer doesn't let me test it out very well.

Are you using the FLASH example instead of the RAM (default) build? Do you have the controlCARD switches set correctly to allow boot from Flash?

are you using MotorWare _12?

Previous versions may not have included the CodeStartBranch.asm in the Flash project that is required for boot from flash.

I had the controlCARD setup for flash but I was still using the RAM build. Got it running now, thanks.

Also, for anyone else with the same problem, with the FLASH build you still have to #define FLASH in the project. It's not automatically defined when you change the configuration.

Thanks for reporting. I haven't run a 6x from Flash in quite some time, I'll file this as a bug and see if we duplicate.
