OPTIONAL—Only required if you have problems or want to see the boot console output.
Connect the micro-B end of the USB cable into debug port J17. Connect the other end of the cable to a PC acting as a host terminal. Three UART connections will appear on the PC. On a Linux host for example:
ls -l /dev/serial/by-id/ otal 0 rwxrwxrwx 1 root root 13 Feb 13 12:59 usb-0403_FT4232H_9266A2-if00-port0 -> ../../ttyUSB0 rwxrwxrwx 1 root root 13 Feb 13 12:59 usb-0403_FT4232H_9266A2-if02-port0 -> ../../ttyUSB2 rwxrwxrwx 1 root root 13 Feb 13 12:59 usb-0403_FT4232H_9266A2-if03-port0 -> ../../ttyUSB3
Using a serial terminal program like minicom, connect to the port with
if02in the name (in this example
ttyUSB2) and apply the following configuration:
- Baud rate: 115200
- Data bits: 8
- Stop bit: 1
- Parity: None
- Flow control: None
Ensure that the power is off (SW10)
