To be pedantic, is this the board?

https://www.digikey.com/eewiki/display/LOGIC/Digilent+Arty+A7+with+Xilinx+Artix-7+Implementing+SiFive+FE310+RISC-V

Are there any accessories or JTAG you need? If you have a JTAG adapter you
know works,
please pass that along.

How different are the instructions there from what would be required when
using RTEMS?

I don't recall. Did you post test results?

Did you look at the performance at all? There are no known performance
issues but
always worth asking.

I'm thrilled to see this merged and available. Just wanting to ease the
startup for using
RTEMS on it.

Thanks
