Hi,
How are you?
I am getting this error.
[15:06:42] Started sgminer 5.5.5-aeris
[15:06:42] * using Jansson 2.11
[15:06:42] Loaded configuration file sgminer.conf
[15:06:42] Specified platform that does not exist
[15:06:42] clDevicesNum returned error, no GPUs usable
[15:06:42] All devices disabled, cannot mine!
Try with
"gpu-platform" : "0"
Also, I recommend intensity 21 instead 22 for your RX 480
