Hello
I am using the LPC Link as a standalone device with my board that has LPC1114/202 MCU. I am trying to run the blinky example available for LPC1114/302 by modifying the LED port and bit number.
The problem is that the IDE doesnt go into debug mode as it returns an error saying " Failure to connect: Bad ACK returned..wire error" .
When i ground the ISP pin through a connector, then it doesnt give this error but then u cant use LPCXpresso IDE for debugging in this mode.
Can you please give me some ideas, whta could be going wrong?
Thanks.
Seems you are using customized target board.
Please Check:
1) Does your customized target board powered properly?
2) Do you release the ISP pin?(If ISP always grounded, it will return this error message)
3) Check you debugger connection.
Most likely is reason 1) or 2)
