Machine: Avalon 4.1.
Issue: This machine is sometimes able to run at the advertised speed (~1100 gh/s). Other times when cgminer starts, it runs at either 200 gh/s or 0 gh/s. But this appears to be setup and/or pool dependent.
Setup: Running via a raspberry pi with openwrt. No AUC. Instead, connected directly to the pi headers with command line option --avalon4-iic-detect.
Works: Previously, when using an AUC connection and connected to a Linux machine running cgminer built with --enable-avalon4. The machine worked at full speed. But in order to get this, it's necessary to restart cgminer about 10 times. With 9/10 tries, the machine runs at 200 gh/s, or worse, at 0 gh/s. Another variation is that during this setup, the machine would only be able to mine at full speed when connected to eligius pool (and that is after restarting cgminer about 10 times). F2pool or slushpool would not ever go above 200 gh/s.
Here is the log (
https://pastebin.com/embed_js/MiVCQDSj) from running the command:
cgminer --lowmem --avalon4-fan 20 -o stratum+tcp://stratum.mining.eligius.st:3334 -O <hidden>:anything --avalon4-iic-detect --avalon4-freq 420:390:360 -l 1 --avalon4-voltage 7625 -D --verbose 2>output.log
Any help is greatly appreciated!
