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

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

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
