The SmartLynq+ can also be used as a serial terminal to remotely view the UART output from the VCK190. This feature is useful when physical access to the remote setup is not available. The SmartLynq+ module has the minicom application pre-installed, which can be used to connect directly to the UART on the VCK190.
Using an SSH client such as PuTTY on Windows or ssh on Unix-based systems, connect using SSH to the IP address shown on the SmartLynq+ display.
Username: xilinx
Password: xilinx
For example, if your SmartLynq+ displays an IP address 192.168.0.10, you should issue the following command: ssh xilinx@192.168.0.10.
By default, the minicom application uses the hardware flow control. To successfully connect to the UART on AMD boards, hardware flow control should be disabled as it is not used on the VCK190 UART. To do this, enter the minicom setup mode by issuing sudo minicom -s and disabling the feature. Alternatively, issue the following command as root to modify the minicom default configuration:
echo "pu rtscts No" | sudo tee -a /etc/minicom/minirc.dfl
Finally, to connect to the VCK190/VMK180 serial terminal output do the following:
sudo minicom --device /dev/ttyUSB1
Leave this terminal open and proceed to the next section.
