LPC55S69 support JLINK ？

[superliyou]

When use GCC development, I can compile and obtain the 'elf'  use ARM GCC tool chain.

How to connect the board with JLINK pod?  

Is there any reference document or configuration(include hardware and software)？

thanks a lot ！

For the hardware, you need to attach the debug pod to the debug pins of the MCU. Either JTAG or the simpler SWD. I suggest to consult some development board schematics as example. Using the same connector and pinout like those eval boards might save you from preparing special adapter cables. The JLink output is the standard ARM 2x10 pin connector, which very few vendors put on their dev boards.

The MCU itself does not care about the brand of the attached debug pod, but your toolchain (debugger) needs to support it.

JLink would be a good choice, and as mentioned, the free MCUxpresso IDE supports it.

thanks a lot !  JLINK have a 20 pin connector with Pin spacing 2mm. and the LPC55S69 SWD interface（P7）is a 10 pin with 1.27mm。 I need an adapter board。Maybe can also be connected by multiple single wires according to the interface definition on both sides。

You might need to make one yourself, which should not be a problem. I have done so more than once.

I think SWD does not support multiple targets or "daisy chaining" like JTAG.

Yea, you can do that. Or there arre lots of companies that sell adapters, such as Olimex. Search for “arm  JTAG 20 10 adapter”

Use MCUXpresso. It uses GCC compiler and has debugger built in, including support for J-Link. And it is free.
