How to Connect a Debug UART
The debug UART port on the
Open-Q™ 605 SBC
can be found on the Expansion Connector
(J3600) (for Expansion Connector pinout information, please refer to section 3.11). To access the
debug UART, follow the pinouts in Table 3-2 below. Note that the UART interface voltage level
is 1.8V.
It is recommended to use a serial-USB adapter cable such as the TTL-232RG-VREG1V8-WE
from FTDI. Available here:
