Suggestions wanted on IOC hardware

["James P. Withrow via Tech-talk" <tech-talk at aps.anl.gov>]

Hello all-

I'm investigating the eventual migration of our control system to EPICS, and as such, I would like to solicit community input on IOC hardware which I can use as a 'boilerplate' configuration for common tasks like sensor (I2C/SPI) polling, instrumentation (RS232/485), and general IO.

• Ideally runs RTEMS and EPICS easily, with Linux and EPICS as a second choice.
• Supports GPIO and standard peripheral interfaces such as SPI, I2C, and UART.
• Can be initially set up with a standard configuration but be customized as needed.
• Has reliable persistent storage for operating system and configuration data.
• Is slightly more powerful than we think we need at the moment to allow for future-proofing.

Current searching has turned up mostly references to Beaglebone and Zynq hardware, however I'd like to hear from community members as to what's in use 'in the wild' and how well it works - or doesn't - for your applications.

Thanks!
