how to start program from flash memory for PICCOLO F28069 device.

What do you mean with debug mode? The program is in the flash and the program counter is at your init function? Try to reset and start it without Run->Restart before. Does this work?

If not: I think you forgot to initialize the flash start vector. You will need a "lb _c_int00" instruction at the flash reset vector.

Dipankar,

Is your code in RAM (or) FLASH? If you trying to execute an application from flash standalone, this document (Running an Application from Flash (spra958)) should help you.

Thanks Edwin,

Hi,

I am not familiar with the piccolo devices (but with all other c2000 devices), but I suggest that you follow the instructions of spra958. And check the examples.

Best regards and good luck

Dipankar,

This warning is fine and can be ignored. It is just telling you that the entry point for the program is set to code_start instead of the default _c_int00 which is what we need in these examples. Other Peripheral Examples provided by TI will also generate this warning.
