2008-04-24 06:21:21 disable console on ttyBF0

I want to have a console on ttyBF0, and disable the console while starting my application.
My application uses ttyBF0 for communication with another device, so at the start of my application I want to detach the console functionality.
I do not want to disable the console by compiling the kernel or by passing an argument with u-boot!
hope someone can help.

There are a few things that are being mixed up (I think):
- uart as /dev/console (where kernel prints out messages)
- uart as /dev/ttyBF0 (shell interface)
- uart as /dev/ttyBF0 (application interface)
If you can describe what you are trying to do to all three different use cases, I think we can help.

I have the same problem. My application is lunched from rc. In the previous version of uboot I wrote in bf537-stamp.h something like
bootargs=root=/dev/mtdblock0 rw console=NULL
Than, in my application, I wrote
fd = open("/dev/ttyBF0", O_RDWR);
and worked with another controller or computer through the serial port. What should I do now, with last versions of uboot and uClinux?
