I am working with a custom board with LPC812. I am getting following issues while connecting it with LPCexpresso:

1- In the debugger option it is showing only SWD mode not JTAG.

2- I am not able to connect in SWD mode. Error is " cannot connect to core"

plz. suggest a solution.

1. The is no JTAG debug on LPC812 it is SWD only for debug

2. Check your debug circuit: https://community.nxp.com/message/630601

There's a power problem, or there's something wrong with your debug circuit. Pay attention to the debug circuit design recommentations, and sharing GND.

Thanks and regards,
