How to know it started first time after flash firmware.

[mobi]

I'm actually writing some data to the flash. I'm using pstorage api interface.

But whenever I flash the new firmware, I get some garbage data. in my main function I would like to know that, after flashing a new firmware, it started for the first time, so I clear the garbage data, and want to make sure it is not result of a reset or a manual reset etc.

Thanks

BTW, can you point me where to get some more knowledge about flags? what you have suggested? So, on flashing the firmware if I can set some flag. And when the application runs I can check that flag. Can I also reset that flag from that application again ? Thanks
