Hi Ian,
1. check the power supply, J38 should be set to 3-4 for power from USB
2. check the switches to set the board to ISP mode: SW1: 0001 (to run the application, change the switch to 0010)
Here is the photo of RT1170-EVK, where the jumpers are located and where the cable should be connected. RT1160-EVK should be similar.

Regards,
Marek
