When MFG_NC1 and MFG_NC2 signals are not routed to connector CN41 (i.e., jumpers JP20 and JP21 are set to position 2-3), then it is
possible to have a debug USB port on mini-B USB connector CN42
This debug USB port is realised converting the Debug UART signals to USB by using a Silicon Labs
®
By using Silicon Labs
VCP drivers on the PC connected to this USB port (drivers available at
uart-bridge.aspx), the debug USB port will be exploitable by any COM port application, exactly like if it were a standard serial port. Please remember that Qseven
module will have to work in device (i.e. client) mode.
