Debug USB 

For the output of debug messages of the TQMa8Xx the MBa8Xx can be connected as USB device via X13 to a host. 
A total of four UART interfaces are provided via the USB interface, which are converted to USB with the 4-port bridge FT4232. 
Available UART interfaces: 

 

UART1 for the Cortex-A35-Core 

 

SCU_UART for the SCU 

 

2 × UART at pin header X4 (freely usable, e.g. for additional multiplexed UARTs or SCU-UARTs) 

 
 
The interface is powered from the external USB host, independent of the MBa8Xx supply.
