Paul, thanks a lot. What type of developer board do you use?
Which type of electrical interfaces do you provide for controlling CNC
(servo, stepper, field-bus, real-time Ethernet)?
Do you have some results of latency tests available?

Our company is also working in the motion control section for over 20
years now.
We mostly build "intelligent" controller cards (for example
http://www.rw-gmbh.de/gallery/3-mcu3100/detail/4-mcu3100).
Up to now we have built our CNC firmware based on an own built minimal
RTOS with very low latency (some few microseconds).
We currently check the possibility to switch over to an generic
available OS with real-time support.
The i.mx6 series processor has been selected because of scalability,
long term availability and PCIE root complex end endpoint support.
Our plan is to develop an intelligent PCIe card based on the i.mx6S/D/Q
for Linux and Windows hosts and also working as a standalone controller.
