I'm trying to send the "hello world" demo that I got from the SDK I built on the MCUXpresso SDK Builder, and it builds fine. When I go to test the debugger, however, the debugger gets to about 97%, and then sends me an error message saying "02. Failed On Connect: Wire ACK Fault in DAP Access" I downloaded this MBED serial port driver: Windows serial configuration - Handbook | Mbed for my TWR_K65F180M MCU. Why does this error message come up and how can I fix it?
Solved! Go to Solution.
Your method did not work for me, but just drop-and-dragging a led_blinky.bin example from the online compiler (ide.mbed.com) did fix the board. Also my board (FRDM-K66F) had a red light on by the usb port.
