Dear all:
In general, we use serial port log to debug some boot issue.
But if the device has not native serial port, such as APL NUC, then we have to use the
USB serial port convertor.
However, you can get log only after the kernel load the USB serial port convertor
driver. If the kernel crash before load the driver, then you have to check log in screen.
In the cel_apl lunch target, default use ttyUSB0, and the other lunch targets are use
ttyS0.
Now support FTDI or PL2303 chip based USB serial port convertor. You can enable others
as you needed.
Some USB serial convertor:
