Yo guys,

I just now flashed my HK v2.1 board with xcopter, there was lights on my avrusb programmer but is there any way to check where it was programmed if yes then how??

There is no way to check which firmware currently loaded. You can check eeprom values in lazyzero tool.

If you are using KKmulticopter flash tool by lazy zero then you get message in console by avrdude that firmware is flashed and verified.
