USB ports[edit | edit source]
Description[edit | edit source]
SBCX provides two USB ports, one Host and one device:
- J17 is a standard USB Host 2.0 Type A connector
- J18 is a micro-AB type receptacle for a USB device connection: this interface can operate in Device (peripheral) mode and - optionally - in Host mode
Signals[edit | edit source]
The following table describes the interface signals

Device usage[edit | edit source]
The USB Host port can be used under Linux for connecting USB peripheral devices: the related peripheral driver has to be integrated into the Linux kernel.
The USB Device feature can be easily tested using the Mass Storage Gadget driver. (*) This port can operate in Host mode using a proper BOM mount option. See the EVK schematics for more info
