Rasbian Serial Console Configuration
By default the base MyPi Raspbian images have the serial console enabled on UART1 (ttyS0), these are pins 8 & 10 of the Raspberry Pi HAT connector
To use the console cables purchased from the eshop you first need to install the Prolific 2303 driver
After downloading and installing this driver software you should plug in your cable, you can verify this has been detected and which COM port has been assigned by looked through the Windows device manager
If all has been installed correctly then you should see an item like the below appear :
This tells us that the device has been installed correctly and is active on COM18, if you do not see this message try reinstalling the driver with the cable plugged in.
The next step is to connect up the cable to the board, it's important that the Red +5V wire is never connected to the MyPi board, so take a moment to snip this wire off to avoid any mistakes.
Noting that Pin 1 is show in top left (next to the ASIO connector) here's the wiring order to follow:
With that all connected up start up a serial terminal program like Putty or similar
The serial port configuration to use is baud 115200 with 8N1 data/parity/stop bits - this can be altered by changing the boot config setting in /boot/cmdline.txt
Start up the board and the following will appear, followed by the login prompt
To disable the serial console you should remove the below from /boot/cmdline.txt
dwc_otg.lpm_enable=0 console=serial1,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait
And then run :
# systemctl disable serial-getty@ttyS0.service
