    Is it not direct now? My situation is always direct. I'd like to know how to set this function to set/cancel "login".

    I believe that you have to "login" to Linux to use it, but not for it to boot up.

    If you are referring to the system not booting till you log in through the terminal. There is a way around that. Simply remove the jtag serial device from you design in Quartus SOPC builder. Recompile, and remove the JTAG serial driver from the Linux kernel, it will boot up without login. Make sure you setup your rc file to either get or set the IP so you can telnet in if need be. Otherwise you will be good to go.

    Hi supercjb,

    If you want to go directly to the shell (without the login prompt), you need to

    change your console inittab entry:

    From something like this:

    ttys0:vt100:/bin/agetty 115200 ttys0

    To something like this:

    ttys0:vt100:/bin/sh

    Regards,

    --Scott

    I yet have to see a first good reason why one should not login and just get a shell after powerup. Be very carefull when you do this, these are the type of blunders that tend to get in the final (released) product.
