i.MX8MP USB Configuration for Serial Download Mode

[Wobaffet]

Hello,

We are working on our prototype board, we pulled the Boot Mode 0 pin to high so MPU should be in Serial Download mode. For the prototype board USB, we only connected power, ground and data +/- . Is this configuration should work or we are missing out on something else?

Thank you in advance!

Hi @Wobaffet,

I hope you are doing well.
Please accept my apologies for the delay in response.

Yes, your understanding is correct. Only four connections are required for the USB Serial Downloader mode.

Thanks & Regards,

Hello, may I ask if VBUS is required for the RT1176 MCU to be in serial download mode or at least to be recognized as a USB device by the PC?
