If you mean which version of RPi OS I was using, I was using the latest lite version
I'm pretty sure all of us here are using the standard Raspbian OS. Why not just give that a try?
Edit: Or was the Lite version working for you initially?
I just read your original message. You may have a bad or corrupted SD Card. Have you tried reformatting it and reloading? Or may try a different SD Card.
SD card is nor corrupted at all. Also checked the other 4 SD cards that came in the package and they're all fine. The Lite version works great, it's just that the cgminer directory disappears when I restart PuTTY on my laptop (using for SSH into the Pi). No idea how to even find or open a directory in Linux, as I main Windows 7 and newer.
At this point, I wouldn't mind working with the creator of this version of cgminer to make a Linux based OS that has cgminer preinstalled and just needs you to put in the mining pool, username, password, and frequency for the miners to run at.
Also, if it helps at all, I'm using 2 NewPac USB stick miners, a small USB fan, and a Sabrent 14 port powered USB 2.0 hub.
