You can refer to LPCXpresso5536_EVK-DESIGN-FILES.

You can measure JP77(1) or JP77(2).
(2) SCL SIGNAL
You can measure JP7(1).
Hope this will help you.

		Hi @luna_liang
I can reproduce this error message, and the reason for this error is that you directly clicked on Start debugging project.
The I3C's pin is reused with SWD, which makes it impossible to debug SWD when using I3C.
So please use ISP mode to download image.
For specific operating steps, please refer to read me.
Hope this will help you.
