Interfacing emulator xds100v2 with tms320F28027 flash memory

Other Parts Discussed in Thread: TMS320F28027

Part1

I want to download program code into flash memory of TMS320F28027. I believe the xds100v2 emulator can do that. After program code is downloaded into flash memory. Does the emulator have to be keep on plugged in to the DSP, where DSP is now connected to the main circuit and program boots from flash memory (I am assuming this happens).

Part2

My second part of the question is  when XRS (Reset) is toggled from 0 to 1 does the program counter return to the first memory address of the flash memory? where the program code stored in flash memory ( from part 1) can boot ?

    If you want to debug the code while running from flash you need to connect the debugger after flashing else you can very well remove the debugger. The code will boot from flash after a power reset.

    Yes. You're very right.
