I have purchased a new TMS320C6474 EVM. After I received the product, I pluged in the power supply, and tried to connect via USB. But I saw that the RED configuration LED which is named as DS3 on the board is not turned off. It stays in RED. To make this LED to turn off, I tried to push the button named SW1 which resets the board. And I observed that at some times, after we reset the CPU, the red LED turned off. So I predicted that there is a problem with my reset configuration at some times. Do you have any idea about this issue?
