Hi Everyone, I am beginner with MINI2440 board and would like to know how to disable remote console on ttySAC0 so that i can use that port with RS232 device. I cannot find file /etc/inittab as mentioned in one of the posts http://www.linuxquestions.org/questions/linux-embedded-78/busybox-serial...
Hi Place the switch in the NOR mode and boot your mini2440 board. In the bootloader menu you will get an option to change the boot parameters. In that settings you will see the default option is "console= /dev/ttySAC0" . change that to the other serial ports that you are not using. Otherwise you can remove that entry in the boot parameters and see what happens. I am not sure what will happen if you remove that entry.

Thank you so much for your reply! Actually i want to use all 3 serial ports in my application. So i will try removing the entry and see what happens. Thank You again!
OK! I tried to remove the entry "console= /dev/ttySAC0" from linux_cmd_line parameter but device hung up after booting. It seems it must have some console defined to output kernel massages. But i need RS232 port just to write data to the device and i dont want to read in. and by surprise it works for me!..I am able to send data out through ttySAC0. is that correct behavior? Thanks for your inputs!
Hi, I need to disable remote console on ttySAC0 in the new version of nanopc but I can't find the file to modify this feature. Thanks in advance.
