Debug interfaces

JTAG

The ConnectCore 8X SBC Pro provides a Tag Connect footprint for accessing the i.MX 8X JTAG debug
port. This footprint is located on the bottom side of the board.

SWD

The ConnectCore 8X SBC Pro provides two options for programming and debugging the
Microcontroller Assist carried by the ConnectCore 8X SOM:
The first option is a 2x5, 1.27 mm pitch pin header (J9) on the top side of the board that, by default, is
not populated. The following table shows the pinout of the SWD connector:
Pin Schematic signal name Description
1 VCC_MCA
2 SWD_DIO/PWR_IO
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 side of
the board.

Console port

As the debug console port, the ConnectCore 8X SBC Pro provides a 4-pin, 1.25 mm pitch connector
(J11). The UART2 port of the ConnectCore 8X module is used for this purpose. The console signals is a
serial TTL, which travels through the console connector directly to the i.MX8X 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:
