Just got a s9 batch-17 and... Bitmain has changed the firmware, is now BMminer v2.0. I will post in detail tomorrow but for a summary of changes:
- They have changed the hash board channels and therefore die temp reporting channels. Now using channels 6, 7, and 8. Might need to come up with a routine to scan the die temp channels and only use ones reporting something...
- Looks like changing the frequency may be gone. In the Bitmain GUI that choice is gone. On startup, the firmware goes through several checks per-board and sets the best freq and possibly Vcore as well. When all is done, the boards report different frequencies.
Looking at the Kernel Log it shows several lists of freq and voltage it tries for each board. A note at the beginning of each list says that freq is now stored in the PIC. Now does that mean that a warm boot bypasses the testing -- dunna know but hope so. I'll post the Kernel Log tomorrow. Also fan speed no longer has a setting on the BMminer GUI. Log says is set as needed starting at 40% Oh, the fans are on different channels as well. Think fans are now reported in positions
Due to the time it takes for the new rebooting process -- around 4 min -- better set dead miner/offline/etc to wait at least that 4 maybe even 5 min before trying to issue another reboot call to the miner...
Other than that, everything else works fine inc the Web access and info to it.
