I will need Linux kernel with SPI support for communication with APA102 LED strips. Also I want to attach a second USB-Ethernet adapter and use bridge-utils to create internal switch between built-in ethernet and the other ethernet port.
I don't have much Linux experience, I'm mostly windows programmer, but I could follow some tutorials to make my prototype working.
Is Linux support for the A20 model reliable enough for production use? Or should I better pick one of earlier Olinuxino models?
Yes Linux is stable for A20. Now it's Debian stable version, also kernel is stable, but It's also a little bit old.
SPI I use in my project and it's working without any problems the same as I2C.
Thanks for the reply, so I guess I'll give A20 a try :)
