Hi Miroslav,

Thanks for your fast reply.

As said in that link if i give "console=null" in bootargs it wont print the log till booting. Actually i need to see the logs till booting and then want to disable console.

Thanks

Hi Shinu,

What I understand is that you wish to disable the linux shell console after the kernel has finished booting.

This can be achieved by modifying the /etc/inittab file on your root file system. Find this line:

S:2345:respawn:/sbin/getty 115200 ttyO0

and comment it out:

#S:2345:respawn:/sbin/getty 115200 ttyO0

Then type in the following command if you are doing the modification at run time:

init q

Best regards,
Miroslav

Hello Miroslav, Shinu,

Can you please let me know what modifications I need to make in order to use it as a port that can be used to send and receive binary data?
