I use the SMARC-sXAL (E2) SMARC 2.0 module https://www.kontron.de/products/boards-and-standard-form-factors/smarc/smarc-sxal-e2-.html with the SMARC Evaluation Carrier 2.0 evaluation system https://www.kontron.de/products/boards-and-standard-form-factors/smarc/smarc-evaluation-carrier-2.0.html.
# cat /proc/cpuinfo | grep "model name" | head -1
model name : Intel(R) Atom(TM) Processor E3930 @ 1.30GHz
Do you need more information about the hardware?
The operating system is Linux with kernel 4.12.14.
The mcp251x driver can be loaded
