Is cgminer supposed to be upgraded automatically when the firmware is upgraded? I just performed the firmware upgrade on one of my SP20s and it still shows cgminer 4.7.0 on the dashboard page.
Try a
Reboot from the miner's home page. That's what did it (cgminer 4.8.0) for me.
I've upgraded all my SP20's to firmware 2.6.1 and have done reboots on all of them. The dashboard page still shows cgminer4.7.0 .
I'm running 2.6.9 on all mine and have the same issue, cgminer4.7.0
You will see 4.8 if you set the flag to 2, used to mine on nice/west hash with extranonce.subscribe enabled otherwise you will see 4.7 as you are.
EDIT: Taken from nicehash ASIC guide page:You can also download pre-compiled binaries for Spondoolies SP2x and SP3x with cgminer 4.8 and extranonoce.subscribe patch and replace stock Spondoolies cgminer (instructions included in README file). Please note that this cgminer is already included in latest Spondoolies SP2x and SP3x firmware!
