Hi, I have a bunch of these BB Black boards extracted from Bitmain Antminers S4/S5/S7
Is there any way that I can reuse them?
thx in advance

Maybe... They are pretty neutered.. No usb power, dc power jack. Power
over header... Looks like a nand flash, we never used that, so the
boot pins are probably different..
What's the used resale market on them?
A BeagleBone Green is around $44 new..

So if you can sell them for more then $44, i'd do that..
If you want to play around, start with this image:
It'll at-least get you into u-boot, so you can read the board eeprom..
(in theory)..
But yeah, no support, i don't have any of these..
Regards,
as long as they respond to ssh is good since i can try what to do afterwards
thanks in advance
soldered a DC power header to turn it on without the secondary controller board that comes with the miner
used the image you recommended without success… it just refuses to boot
flashed the original firmware using hdd raw copy tool and it boots normally
original firmware https://bitmain.zendesk.com/hc/en-us/article_attachments/201659685/S4_Jan_29_Image.imgc
perhaps you can stripe open said image to compare?
I also have a board like this. Going to solder a usb micro-b connector on it to power it. Which is a type that fits well?
Do I also need to add capacitor C34 to the board? I see in photographs versions of 10 V and 6.3 V.
