Correction here for the list archive. I should have put
--sys-clk-freq=55e6 not simply -sys-clk-freq=55... dumb assumption on
my part that the Xe6 was implicit. Thankfully as soon as I tried to
run ./versa_ecp5.py --fpga ulx3s85f --sys-clk-freq=55 --build it
failed with an assertion error because duh 55 isn't above the clock
threshold :)
