Carrier Board PCB Designing Tips for SoM FETMX6UL-C Users
All 24 data lanes of the LCD are for booting configuration, please do not do pulling up or down operation to them, otherwise, it may cause the SoM boot failure(SoM voltages are normal and LED lighten up, but no serial port printing information output).
When working with USB, please circuit USB_OTG1_VBUS and USB_OTG2_VBUS to 5V power, otherwise, you may get errors. I f to connect USB_OTG1 to HUB chip, please pull-down ID pin.
