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.
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,

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
I have connected SWDIO,SWCLK and GND from LPC-Link-2 board to my custom board as suggested, Still same error.
plz. suggest.
