Hello!

Thank you for coming to E2E with your question!

The GUI will return this status if SW21 (button) has not been pressed.

The EVM returns connected because the USB communication is active after SW28 has been switched on but the controller itself DLPC3479 is not powered on yet.

Best,

Aaron

Hi Aaron,
Thank you for your reply! We found out that the EVM status will be powered off if there's an error when we are developing our software. So, I guess it's not a hardware issue.
Thanks,
Yi Tian

Hello Yi Tian,

Are you saying that the status "EVM Status: Connected, Powered Off" will be seen even after the SW28 is pressed - initializing the controller?

Best,

Aaron
