Is there any difference between the USB1 and USB2 ports on the i.MX 8M PLUS?

Hi all,

Q1) According to the documentation provided by NXP, the two USB ports on the i.MX8MPLUS appear to have the same functionality. Is our understanding correct?

Q2) Does the USB Serial download mode work on either port?
       *Is there a setting to prioritize one port over the other?

Thanks,
George

Hello @Bio_TICFSL,

Thank you for your answer.

I have confirmed that Serial-Download mode does indeed work on both USB ports using the IMX8MP-EVK.
It seems that which port is used for Serial Download is determined by USBx_VBUS.

Thanks,
George
