On the picocom terminal, you can control the counter behaviour to stop it, or let it count backwards, by toggling values of the EMIO pins of the ARM Processing System (PS).

You can control the counter enable signal with:

gpio set 54
gpio clear 54

If GPIO 54 is set, the counter is disabled. It is enabled if the GPIO 54 is cleared. The result should be as follows:

I build the counter test, scp top.bit to the pi, load it:

openFPGALoader -b arty top.bit

The lights blink as expected, so it is loaded. But this doesn't echo anything and I suspect it isn't working:

picocom /dev/ttyUSB1

I type gpio set 54 and nothing echos and the lights keep blinking.
