IMX6 Custom baudrate 10000

firassobaid — Thu, 06 Mar 2014 07:58:23 GMT

Hello,

I have IMX6 chip and I am trying to use RS232 with baudrate 10000 (custom)

but I cannot implement it.

Can anyone please tell me how to achieve this goal?

I am using IMX6 with Android OS (C coding using NDK)

Thank you

That is not a standard baud rate.

yeah, i am looking for Custom baud rate 10000
Is it possible in IMX6 ?

Please try to add your custom baud rate into drivers/tty/serial/serial_core.c

and drivers/char/tty_ioctl.c source files prior to OS compilation.

Victor Linnik, I did not find drivers/char/tty_ioctl.c , I did find drivers/tty/tty_ioctl.c

but when I compile I get this error:

CC	drivers/tty/n_tty.o
CC	drivers/tty/tty_ioctl.o

drivers/tty/tty_ioctl.c:213:36: error: 'B10000' undeclared here (not in a function)

make[2]: *** [drivers/tty/tty_ioctl.o] Error 1

make[1]: *** [drivers/tty] Error 2

make: *** [drivers] Error 2

How did you configure it? I wanna use a custom baudrate too but I dont know how to do it.

Please check the formular in 64.5 Binary Rate Multiplier (BRM) to set the baud rate.

Could you write it clearly? I am just a newbie.
