Thank you so much for the time you've invested to make the S4 more funtional, ckolivas. I'm going to send you a donation tomorrow morning.
I'd like to try ck's new version tomorrow, but I have no idea how to go about updating cgminer. Can anyone shed some light, or point me towards a guide?
Assuming your S4's IP address was say 192.168.1.99:
ssh -l root 192.168.1.99 (or equivalent with putty)
wget http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer
mv /usr/bin/cgminer /usr/bin/cgminer.bak
chmod +x cgminer
mv cgminer /usr/bin/cgminer
/etc/init.d/cgminer.sh restart
I think that might not keep across a power cycle though.
You were right, the changes don't stick across a power cycle. Is there any way to make them permanent?
