Debug Serial UART over USB J800
Figure 3-9 Debug UART over USB J800
The UART connection used on the Open-X 8M is a USB micro B connector (J800). The debug
UART is available over USB via the SILICON LABS CP2105 chip on the carrier board.
UART1_TXD and UART1_RXD are used to output serial debugging information for A53-core.
UART2_TXD and UART2_RXD are used to output serial debugging information for M4-core. No
RTS or CTS signals are sent from the Processor to the Debug connector as these signals are typically
ignored by most applications. To get the serial terminal working with a PC, user needs to ensure that
the appropriate SILICON LABS drivers are installed.
The terminal settings are as follows:
