'''Note&nbsp;:&nbsp;'''

Please connect device's TX to usb2uart adapter's RX and&nbsp;device's RX to usb2uart adapter's TX .







= UART parameter =

*BaudRate：115200
*DataBits&nbsp; ：8
*StopBits&nbsp; ：1
*Parity&nbsp; &nbsp; &nbsp; ：None
*FlowControl：None or XON/XOFF



= Debug on windows =

Install usb2uart adapter's driver. Connect adapter to PC , you will find COM port like&nbsp;:

Then Click "Open" to start debug console.



= Debug on Ubuntu =

"Kermit" and "MiniCom" are very famous tools on Ubuntu.

&nbsp;Connect adapter to PC , find COM port&nbsp;:
<pre>$ ls /dev/ttyUSB*
/dev/ttyUSB0
</pre>





== Kermit ==

'''Install Kermit&nbsp;:&nbsp;'''
<pre>sudo apt-get update
sudo apt-get install ckermit
</pre>

'''Config Kermit&nbsp;:&nbsp;'''
<pre>vi $HOME/.kermrc;

set handshake none
set flow-control none
robust
set file type bin
set file name lit
set rec &nbsp;pack 1000
set send pack 1000
set window 5

</pre>

'''Note&nbsp;:&nbsp;'''

Change "/dev/ttyUSB0" according your system, Use Command "ls /dev/ttyUSB*" .

'''Run kermit'''
<pre>sudo kermit
</pre>



= MiniCom =

'''Install MiniCom:&nbsp;'''
<pre>sudo apt-get update
sudo apt-get install minicom
</pre>
