I have a board with MIMXRT1062DVL6A and I've stuck with USB. It has to work as a simple virtual COM port.
USB is connected this way. Connection is almost the same as EVK board. The only difference is that OTG is not routed to pin H10 and VBUS is not routed to pin N6 and they are left floating.
I try to run evkmimxrt1060_dev_cdc_vcom_bm or evkmimxrt1060_dev_cdc_vcom_lite_bm or any USB examples from SDK. After uploading program I got a message from Windows that says "USB device not recognized".
I've checked what's on DP and DM at the time of connecting device to the computer - see the attachment. It's strange that max voltage of DP/DM line during connection is 880mv instead of 3.3V. No idea why.
