7 EVM Operation
7.1 Using Telnet
The initialization file (/etc/init.d/rcS) starts a telnet server. If your development host is in the same sub-net
as the EVM, you can telnet to it using the IP address assigned in the U-boot environment. You can use
the "ifconfig" command from the Linux prompt to find out the ip address of the EVM.
$ telnet 192.168.1.10
You will be prompted for a user name and password. The user name should be root and the password
should be left blank (just hit Enter).
7.2 Booting the New Linux Kernel
After building the new kernel, in order to use it to boot the OMAP35x EVM, you must transfer it to the
board via TFTP. Once you transfer the kernel image to the board via TFTP, you could either perform a
TFTP kernel boot or flash the kernel image to the NAND and subsequently use the NAND boot. It is
assumed you have completed the steps in Section 6.2 Rebuilding the Linux Kernel, and the boot file,
uImage has been copied to /tftpboot (or some other site-specific TFTP accessible location).
7.2.1 Checking the TFTP server setup in the Linux development PC
You can check to see if a TFTP server is set up with this command
# rpm -q tftp-server
If it is not set up, you can follow these steps:
1) To install TFTP, use this command, where
# rpm -ivh /db/ztree/useracct/tftp-server-#.#-#.rpm
2) Confirm that TFTP is installed with this command:
# /sbin/chkconfig --list | grep tftp
You should see the following output:
tftp: off
If you need to turn on the TFTP server, use this command:
# /sbin/chkconfig tftp on
The default root location for servicing TFTP files is /tftpboot.
