How do I login to linux on the board?

  • You can connect a keyboard (if you have a display but no windowing software installed on the board).

    • OR

  • You can connect a null modem cable from a terminal to the linux board.

    If you are using a Linux machine for the terminal, you can use minicom to connect. To setup minicom for your machine use minicom -s to configure minicom, go to 'serial port setup' and try setting the port like this:

      A - Serial Device : /dev/cua0
      B - Lockfile Location : /var/lock
      C - Callin Program :
      D - Callout Program :
      E - Bps/Par/Bits : 38400 8N1
      F - Hardware Flow Control : No
      G - Software Flow Control : No

    Depending on your machine you may need to use /dev/tty1 or /dev/ttyS1 instead of /dev/cua0.

    • OR

  • You can use ethernet to telent to the board. (You have to know the IP address of the board to do this).

Now type 'root' at the prompt and press enter.

Depending on the root file system you are using, you can login (as root) either without a password or with the 'rootme' password.

To change this you can put an encrypted password in the /etc/shadows file by using the 'passwd' command. If you are using a ramdisk root file system, this will be lost when the power is removed. To make the password change permanent on a ramdisk, change the password with the passwd command and cp or ftp the /etc/shadows file from the board back to your development machine. Update the ramdisk as described in this topic, replacing the original /etc/shadows file in the ramdisk with the new one. Download the modified ramdisk (with the password now in place) back to the flash memory of the board and reboot.
