I’m developing a custom baseboard for imx6rex, I need a couple of additional serial port and I want to connect directly a dual port ftdi chip to the rex module without any USB hub chip. Where I have to connect it directly if possible?
you can connect it to any of the two USB ports. It is good to leave the OTG port available for debugging if needed.
If you have a development board of your FTDI chip, you can test it on the Rex first. USB1 is available on header J20. You will need to swap the optional routing resistors R64, R66, R68, R69.
