UART custom baudrate on Colibri iMX6ULL

Hi

Is it possible to set non-standard UART baudrates on a Colibri iMX6ULL? I tried it the way it is described in documentation UART (Linux) for Vybrid modules, but it does not work.

Thanks

Which rates did you try? And what do you mean saying “but it does not work”?

Baud rate can be non standard but it can’t be any. There is a set of fixed clock frequencies used to set a baud rate. When you trying to set arbitrary baud rate driver choosing an available one most close to required.

Hi

I ask because I could only find information about how to do for a Vybrid module, and nothing about iMX6.
So it should work in general and is not restricted to standard rates?

Thanks

Hi

Did you try the example on iMX6 too?

Settings are same. Just use tty device names for iMX6 as listed here

Hi

I now could try with iMX6ULL at 250 kbaud as described for Vybrid, with the mentioned tty device names, and it works. So finally setting custom baud rates is possible with iMX6ULL.

Thanks

Perfect that it works. Thanks for the feedback.
