Debugging or bringing up the card required the use of a USB-to-UART cable that is included in the package contents. Upon inspection, there is a USB connector with USB 2.0 full speed compatibility and 3 single pole 0.1m pitch header that connects to a serial port on the Controller Card. The following figure shows an example of a USB-to-UART Cable, and the table provides the cable signal description.
UART Cable Color Legend and Description
Color | Signal | Description |
Black | GND | Device ground supply pin. Connects to the Controller Card ground pin |
Yellow | RXD | Receive Asynchronous Data input. Connects to TXD output on Controller Card |
Orange | TXD | Transmit Asynchronous Data output. Connects to RXD input on Controller Card |
UART Cable Connected to BF1600 Card
Debugging and loading new versions of the operating systems and firmware requires the use of Type A to Type B USB 2.0 Cable. The following figure shows an example of Type A to Type V USB Cable.
