The hummingboard edge has a RS485 port on UART2? What would it take to get to get this running? The latest build does not have ttymxc1 enabled. And I think the driver for the RS485 is different than the normal RS232 Driver. thanks

Thanks, That helps. I was hoping to find a solution that did not require a change to the kernel to avoid some pain; but that may not be the case. I have asked solidrun for there opionon on this issue and will get back with you once I hear back from them.

The Hummingboard-Edge uses UART2 for the RS485 port. This port is actually tied to a RS485 chip on the board. So it is unusable without the Kernel being modified so I am surprised it is not on the Debian "build". Do you know if there is a plan to add drivers to Debian to support the new hummingboard-edge and hummingboard-gate board?

I am using your Debian (jessie) on the new SolidRun Hummingboard-Edge board. [Linux cubox-i 3.14.14-cubox-i #8 SMP Sun Jul 12 19:03:09 CEST 2015 armv7l GNU/Linux] I am planning on using the RS-485 on the board that is tied to UART2. But I noticed that ttymxc0 (UART1) and ttymc3 (UART4) are the only tty ports that have drivers associated with them. [ "dmesg | grep tty" ] How can I turn on the driver that is associated with UART2 (ttymxc1)? Thanks,
