USB2UART Bridge
There are plenty types of usb to uart bridge in the market . Most of them use the following chip :
Hardware PIN define
RSB4680 debug port pin define :
PIN | PIN Name |
1 | NC |
2 | TX |
3 | RX |
4 | GND |
Note :
Please connect device's TX to usb2uart adapter's RX and device's RX to usb2uart adapter's TX .
UART parameter
- BaudRate:115200
- DataBits :8
- StopBits :1
- Parity :None
- FlowControl:None or XON/XOFF
Debug on windows
Install usb2uart adapter's driver. Connect adapter to PC , you will find COM port like :
Putty is very populate tool on Windows. Download putty here.
Run PUTTY.exe, select Connection type of "Serial" , input COM port found in Device Manager.
Set Parameter like :
Then Click "Open" to start debug console.
Debug on Ubuntu
"Kermit" and "MiniCom" are very famous tools on Ubuntu.
Connect adapter to PC , find COM port :
$ ls /dev/ttyUSB* /dev/ttyUSB0
Kermit
Install Kermit :
sudo apt-get update sudo apt-get install ckermit
Config Kermit :
vi $HOME/.kermrc;
Input the following content :
set line /dev/ttyUSB0 set speed 115200 set carrier-watch off set handshake none set flow-control none robust set file type bin set file name lit set rec pack 1000 set send pack 1000 set window 5
Note :
Change "/dev/ttyUSB0" according your system, Use Command "ls /dev/ttyUSB*" .
Run kermit
sudo kermit
MiniCom
Install MiniCom:
sudo apt-get update sudo apt-get install minicom
Run kermit
$ sudo minicom Welcome to minicom 2.7 OPTIONS: I18n Compiled on Jan 1 2014, 17:13:19. Port /dev/ttyUSB0, 15:57:00 Press CTRL-A Z for help on special keys
According the tips, press CTRL-A, then press Z to show help.

Press "↓", move cursor to "Serial port setup" to Config parameter.
Then press "A"-"G" to set relative content as following :
+-----------------------------------------------------------------------+ | A - Serial Device : /dev/ttyUSB0 | | B - Lockfile Location : /var/lock | | C - Callin Program : | | D - Callout Program : | | E - Bps/Par/Bits : 115200 8N1 | | F - Hardware Flow Control : No | | G - Software Flow Control : No | | | | Change which setting? | +-----------------------------------------------------------------------+
When configuration is done, back to choose "Save setup as dfl" to save as default configuration.
