RT1170 with MCU Link debug probe

[Eugene3]

I'm designing a board with i.MX RT1170.

I plan to use MCU Link debug probe for debugging, so I'm preparing 10-pin connector on my board.

I have some question about the pin connection on the board.

Question

1. Regarding Pin10, which should I connect JTAG_nTRST(GPIO_LPSR_10) or POR_B?

2. Regarding Pin6, is it enough to connect only JTAG_MUX_TDO(GPIO_LPSR_11)? 

Could you share if there is a reference design how to implement 10-pin SWD connector on a board with RT1170.

1. Connect it to GPIO_LPSR_10, if connected to POR_B you will need to ensure that POR_B remains asserted during the whole power-up sequence.

2. Yes, you can add pulls but they are not needed. For connection recommendations, I suggest you refer to the hardware development guide as well as the EVK schematic.

Best regards,
Omar

Thank you, I understand.
