Hello Satheesh,
Regarding the download.bat, the screenshot you've sent shows that the download has been performed successfully. That is the expected flow.
The tests on various test modes should appear on the UART terminal (not the download terminal). After powering up the board, if you have connected the USB cables to your PC, a new COM port should appear in Device Manager. You should use a terminal client (like Terra Term or Putty) to connect to the new COM (serial) port, with a baud rate of 57600.
Regards,
Adrian
