SolidRun Hummingboard Usage
The HummingBoard has a 3.3V serial port accessible on the 26 pin header.You can use this port to run a serial console, allowing you to view boot/kernel messages and also log in.
The serial port settings for the terminal emulator are 115200/8N1, no handshaking.
Configure the Debug Buddy for 3.3V RS232 mode by removing both sets of jumper wires. Then connect the HummingBoard to the Debug Buddy using three wires, as follows:
Connections
