Hi @sukyeong ,

What is your board, EVK or EVKB?

Hi @sukyeong ,

By default, the RT1170 silicon can use both SWD and JTAG modes using the Arm stitching sequence. For the RT1170EVK board, it defaults to use the SWD debug without any board modification. If you want to use the JTAG debug, solder out R187, R208, R195, and R78, because some JTAG signals are multiplexed with other functions.

Regards,

Jing
