Hello all, I am currently working on a UART driver for linux. I am developping a new architecture on which I have 3 uart ports. In this architecture, I know that there will be 3 UARTs, and this driver has to be compiled with the kernel, it mustn't be a module driver. The exact thing I want to do is : 1) use the first uart as console for the kernel, and for the shell at the end of the boot process 2) develop a UART driver for the two others UART port so that the user can access them from /dev/ttyS1 and /dev/ttyS2 I am really confused. What need I to do ? I read lots of documentation on both the web and on some books, but I still don't understand what is a uart_driver, a tty_driver, a platform_driver or even a line discipline. How to register the right driver to make it appear on /dev ? When the user will open the file descriptor in /dev and complete some operations like write, read or ioctl on this file, which function will be called in my driver ? Thanks in advance for your help. Best regards. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
