Hi Vignesh,

is this the green OpenSDA LED? If it blinks, then it is either in bootloader mode or blinks an error code.

In both cases it means you cannot debug it because there is no debug application.

Are you using Windows 10? In that case there is a known problem where Windows 10 can erase the debug application or even the bootloader itself. See https://mcuoneclipse.com/2016/08/01/bricking_and_recovering_opensda_boards_in_windows_8_and_10/ . The article includes a table of error codes too.

I hope this helps,

Erich
