TMS320F280025C: C2000™ microcontrollers forum

Akash Wali

Hi I'm working and new to F280025C controller.

I've dumped the code in the flash of controller for first time in debug it works, but if I restart the board i.e. plug OFF & plug ON the supply the program does not run, needs to be flash again.

I think the issue is with codestart.

As I'm having a Launchpad of F280049C, while flashing the code there is message like shown in below image where it shows codestart while loading program

But while flashing into the F280025C my personal customized board the message is as below, i.e. while programing it doesn't start with codestart where actual Flash Begin address is mentioned

Akash,

Do you have codestartbranch asm file included in your project?

Can you share your project snapshots for 3(b), 3(c) and 3(d) described in the FAQ?

Thanks and regards,

Hello Vamsi,

Thank for your support.

The issue was in hardware as the Two GPIO's which where supposed to be pulled-up for booting from Flash where not in the circuit, so needed to do this changes.

And also even after that the POR circuit capacitor value was to small that the controller was not having proper POR.

Akash,

Glad it is clear now.

I did not bring up the boot GPIOs concern since you said you cleared all the suggestions in the FAQ (Boot mode GPIO check is suggested in the FAQ). Anyways, glad your application is working now.

I am closing this post.

Thanks and regards,

Vamsi
