Hi Ashok Ra,
Please check the following configuration, do you use the adesto_AT25SFxxxA flash?

After you modify the SW8 -> OFF OFF OFF ON, please also press the reset button, then try to connect your board.
Please also check whether your COM8 is really your on board virtual COM port.
BTW, I am will on our Chinese Spring festival from tomorrow, and will back on Feb. 3.
Then, if you have any updated information, I will reply you after I am back to works.
If you are in hurry, you also can create the new case, then our colleague will help you.
Have a great day,
Kerry
