Hi all,

I posted on the mining forum about a problem I had and it got deleted (I must be new...). Anyway, the info was helpful and relevant so I'm going to tack it on here so it can help the next person.

I was using an SD card to attempt to boot a number of used Antminer S9's that I purchased used. The unit appeared to boot but all I got was a solid red status LED light and no network. I tried booting the stock firmware from NAND and resetting the network there and then booting from SD again. No luck.

It was recommended that I add

Code:

cfg_override=no

to the uEnv.txt file. I did that and it worked! The unit was given a proper IP address and I was able to get in to the Braiins OS web interface to configure the miner.

I don't remember the poster who helped me out now, since the original post is missing... but thank you!

I have a similar issue to this where I was using the beta version (braiins-os_am2-s17_sd_2020-11-05-0-7f7650dc-20.11-plus-nightly) on SD and was all fine and dandy but when I went to flash it to the NAND now it will no longer boot up and only gives the RED light. I've tried resetting and also boot from the factory SD image with no luck.
