Antminer T15 Issues: Connection Refused

Hey, I'm new to mining and my antminer T15 isn't hashing at all. I've got the latest firmware and the pings are fine with no packet loss. Do I need to tweak anything in network settings or do port forwarding? Logs are attached. Thanks.

Can you edit your post and wrap the logs in the insert tag? Hit the # button when you edit your post and separate the logs.

I just updated via the GUI. Is flashing with an SD card really different?

Flashing with an SD card is a totally different process. It wipes the firmware and installs a fresh one. Updating is more like patching what's already there. You might wanna unplug Chain[2] and check the two hashboards. If that doesn't work, test them one by one. Check the guide for "Test hashboard one by one".

I bought an SD card and formatted it to FAT32. Downloaded the tarball too. Do I just extract everything and put it on the card? There's another tar file, do I need to mess with that too? Thanks man, but these YouTube videos are all over the place.

The SD card image isn't compressed with.tar. Just download the SD card image straight from Bitmain's page under "Flashing SD card with image". The T15 image is in a zip file; extract it and paste it onto the SD card.

I can't find that link, only the tarball download.

I might’ve found it on the Chinese Bitmain site. Let me know if you get a better link. By the way, here are my updated logs.

Here’s the logs with board 2 unplugged.

Finding it is tough due to the layout changes on the Bitmain download page. Try checking under the drop-down options for your model and look for "flash SD card with image". If you can't find it, here's a direct link.

Thanks, I found it. Still having the same issue though. Tried unplugging board 2 as well but no luck. Any insights from the logs I posted?

Did you look at the new logs I shared?

Checked it out, but it shows both hashboards with 0 ASIC counts. You might need to check the hashboard physically. Grab a multimeter and check the resistance at the test point. Also, look at your PSU voltage and maybe try mining on different pools.

Here’s another kernel log after I cleaned all the connections. I’ll go test the boards too.
