SWD

The ConnectCore 8X SBC Express provides two options for programming and debugging the
Microcontroller Assist of the ConnectCore 8X system-on-module.
The first option is a 2x5, 1.27 mm pitch pin header footprint on the top side of the board that,
n
by default, is not populated. The following table shows the pinout of the SWD connector:
Pin Signal name
1 VCC_MCA
2 SWD_DIO/MCA_IO21 SWD bidirectional data pin
3 GND
4 SWD_CLK/PWR_IO
5 GND
6 NC
7 NC
8 NC
9 GND
10 SYS_RESET
The second option is the ARM 10-pin standard-compliant Tag Connect footprint on the bottom
n
side of the board.

Console port

The ConnectCore 8X SBC Express provides a 4-pin, 1.25 mm pitch connector (J5) as its debug console
port. The UART2 port of the ConnectCore 8X system-on-module is used for this purpose. The console
signal is a serial TTL, which travels through the console connector directly to the i.MX 8X processor. A
TTL-to-USB cable can be used for accessing this console port from a host PC USB port.
The following table shows the pinout of this console connector:
