[yocto] [meta-raspberrypi] enable serial communication pi 3

[yahia farghaly]

I have bitbaked rpi-hwup-image for raspberry pi 3 on sd card and connected
the serial ports to *usb to ttl device* . i have set the minicom to
port: /dev/ttyUSB0
baud rate: 115200
the image is booting fine and i can see the prompt on the screen but cannot
see in my serial console using minicom.
*is serial enabled by default for this image ? *
i also tried ENABLE_UART = "1" in local.conf but doesn't help.

how to enable it ? and what the serial device name with respect to
raspberry pi

thanks,
