Atmel AVR2070 User Manual

 

8240B-AVR-06/09 

the source code and precompiled code have USB disabled. Due to limitations on the 
SAM7X board, if a reset is necessary, the USB cable must be removed and any open 
USB terminal sessions closed and then the board can be reconnected and the USB 
terminal session restarted. 

uTasker also supports a telnet interface through the RJ45 network connector. The 
telnet interface is nearly identical to the serial interface. It offers the same menu 
selections and utilizes the default IP address of 192.168.1.125. This address can be 
changed with the “I” menu selection. The network interface also provides the 
connection for the on board simple web server.  

Figure 4-4-1 shows an example menu interface. The complete menu commands are 
fully described in Table 5-1. 

To access the telnet interface, the RJ45 cable can be connected directly to the PC's 
network interface card or to a hub/router. 

Note: 
If connecting a PC directly to the SAM7X, the Network Interface Card 
(NIC) on the computer will need to be configured to communicate on 
the same IP subnet as the SAM7X. 
 

To start the telnet session simply type “telnet 192.168.1.125” at the DOS prompt and 
press enter. Alternately, on a Linux machine, type “telnet -e / 192.168.1.125” at the 
terminal prompt and press enter. The “-e /” defines the escape character. Once the 
telnet session is started, type “/” and a telnet prompt will appear “telnet>”. Type “mode 
line” and press enter twice to return to the SAM7X telnet session. The “mode line” 
command forces the Linux telnet session to echo characters typed by the user to the 
telnet screen.
