FutureBit Apollo III - Next Gen Home Mining

[huntingthesnark]

Right, so my node is finally synched and looks like it's running fine, and the solo pool is live to other devices on the network.

But no standalone mining is happening, indeed, there's no miner mention anywhere on the UI - I can't even access logs for the miner, it's like it doesn't exist.

The only reference I can find is in system logs:

How do I bring the miner online? Board error doesn't look good...

If you updated via command line this will downgrade your unit to pre-apollo 3 support and will cause this error.

For anyone that received their unit before this week you need to flash your SD card to the image linked below to make sure you are on the latest bug fix release.

All units that shipped this week will have this latest image installed so you should be good to go.

OTA updater wont work for Apollo III until we merge 3 support into mainline in a week or two.

Ah, I did wonder if I'd ended up with an older OS - I did update via command line, so that explains that. Will flash and re-setup - thanks!

<edit: Miner is now hashing! Huzzah>

I  have a question my RMA comes to my house sometime today.

I have the Nvme.2  ssd from the last unit (my Nvme.2 is my own)

   it has up to block 960,000 if I put it in the new Apollo III will it work easy peasy?

or must I add codes on the command line to accept it.

gear came

I used a blank Nvme.2 ssd

You should just be able to put in the synced nvme and away it goes

yeah I did that rather then load a second NVME.2 ssd

and we are mining yeah baby

it needs to settle a bit to get power use on eco but it seems pretty good

maybe 12-13watts
