RT1176 MCU First Bring Up

[Wobaffet]

Hello, 

We have a design for the RT1176 MCU, Our board is not recognized by the PC, but all of the necessary voltages seems to be fine. For the USB Connection we only have, USB_D_N and USB_D_P, and GND. Is VBUS required for a PC to recognize our board as a USB device?

Thank you in advance!

Best Regards.

Hi @Wobaffet ，

   Do you enter the serial download mode, and want the USB be recognized by the PC?

  If yes, I suggest you add the VBUS to 5V, as the MIMXRT1170-EVK also add this VBUS:

  If it is the new board, I suggest you also use the JLINK with JLINK commander to check your board through the SWD or JTAG interface, just make sure your ARM core can be found.

  If the ARM core even can't be found, it means your hardware still have issues.

  You need to refer to the MIMXRT1170HDUG:

make sure the power on sequence is correct.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Best Regards,
